Hello to all…

..Convective showers and isolated strong thunderstorms are possible this afternoon and evening across Southern New England this Monday afternoon and evening between around 1-8 PM. Strong winds, small hail, frequent lightning and brief heavy downpours with brief urban/poor drainage flooding are the main threats. While an isolated marginally severe thunderstorm cannot be ruled out completely, sub-severe criteria hail and strong winds are what most likely will occur today..
..SKYWARN Self-Activation will monitor for any hail, strong winds, wind damage, rain gauge reports in the region. This will be the only coordination message for this event. Pictures and videos of storm damage from the events over the next couple days or prior events in the previous two days can be sent as a reply to this message, via our WX1BOX Facebook and Twitter feeds and to the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated. Below is the NWS Boston/Norton Area Forecast Discussion and Enhanced Hazardous Weather Outlook..

Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms remain possible in Western and Central Massachusetts and Western and Central Connecticut as the remnants of Debby passes to the west of the region. Strong to damaging winds, and heavy downpours leading to urban and poor drainage flooding are the main threats with an isolated weak tornado as a secondary threat with the threat timeframe around 3 PM Friday Afternoon through 1 AM Saturday Morning..
..The Storm Prediction Center (SPC) has continued portions of Western/Central Massachusetts and Western/Central Connecticut in a marginal risk for severe weather..
..SKYWARN Self-Activation with Amateur Radio call-up nets will monitor the severe weather potential for late Friday Afternoon and Evening. Pictures and videos of storm damage from the events over the next couple days or prior events in the previous two days can be sent as a reply to this message, via our WX1BOX Facebook and Twitter feeds and to the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated..

The remnants of Debby will pass well to the west of Southern New England Friday through Saturday Morning. This means widespread heavy rainfall and flooding is not expected in the region. That said, it puts Southern New England and in particular Western and Central Massachusetts and Western and Central Connecticut at risk for isolated to scattered strong to severe thunderstorms being on the east side of the remnant circulation of Debby. The headlines depict the current thinking. Key factors include:

1.) The conditional straightline wind damage and isolated tornado threat could affect a very localized, spotty area or areas within the severe weather risk area making any impacts hyper localized. In addition, any tornadic circulations maybe very brief or not detectable by radar so severe thunderstorm warnings with tornado possible tags may be utilized more ubiquitously for this event with tornado warnings issued for circulations that can be radar detected and seen for a period of time.
2.) Any flooding that occurs will be localized and typical of severe weather events we see over the course of the summer with urban and poor drainage areas at greatest risk
3.) There will be some general gusty winds of around 40 MPH in gusts with slightly higher gusts in the higher elevations and possibly at the coast that could cause isolated pockets of wind damage.

Hello to all…

..Additional rounds of isolated to scattered strong to severe thunderstorms are possible to likely Sunday Afternoon and Evening between 12-8 PM and Monday Afternoon and Evening from around 3-11 PM in portions of Southern New England. Strong to damaging winds, hail, frequent lightning and heavy downpours leading to urban and poor drainage flooding to flash flooding are the main threats..
..The Storm Prediction Center (SPC) has placed Southern New England in a marginal risk for severe weather this Sunday Afternoon and Evening. SPC has placed Western, Central and Northeast Massachusetts north of Route 2 in a slight risk of severe weather with a marginal risk of severe weather from South Coastal Connecticut to Central Rhode Island and interior Southeast Massachusetts north up to the slight risk area..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets will monitor the severe weather potential for Sunday Afternoon and evening and Monday Afternoon and Evening. Pictures and videos of storm damage from the events over the next couple days or prior events in the previous two days can be sent as a reply to this message, via our WX1BOX Facebook and Twitter feeds and to the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated..

On Saturday, most of the severe weather occurred across Southern Connecticut and into the Mid-Atlantic states but one severe thunderstorm caused pockets of tree and wire damage in Plainfield, CT and Coventry RI. The WX1BOX Amateur Radio log and NWS Norton Local Storm Report from Saturday are listed below:

NWS Norton Local Storm Report:
https://wx1box.org/wp-content/uploads/2024/08/LSR-8-3-24.pdf

On Friday, severe weather affected portions of Southern New England. Hardest hit was the Simsbury, Granby, West Suffield, CT area along with East Windsor CT. Other isolated damage were reported in parts of Western, Central and Eastern Massachusetts and Northeast Rhode Island. The WX1BOX Amateur Radio log and NWS Norton Local Storm Report are listed below:

https://wx1box.org/wp-content/uploads/2024/08/LSR-8-2-24.pdf

For Sunday and Monday, more severe weather is possible to likely in at least a portion of Southern New England as a cold front slowly moves into the region attempting to bring an end to the heat and humidity in the region. The headlines depict the current thinking. Key factors will be broken out by each day.

Key Factors for Sunday severe weather potential:
1.) Similar to Saturday, marginal wind shear and favorable instability parameters overcoming some unfavorable parameters to produce severe weather.
2.) Amount of heating and destabilization given some cloud cover in the area to allow for the favorable instability parameters to take hold in the region.
3.) Triggering mechanism in the atmosphere lining up with items 1 and 2 for severe weather potential

Key Factors for Monday severe weather potential:
1.) Whether forcing and a triggering mechanism will reach Southern New England near or just past the time of peak heating for severe thunderstorm development
2.) Wind Shear profiles are expected to be quite strong enhancing severe weather potential in the slight risk area if forcing/triggering can move further south in the area
3.) Instability should be sufficient and if forcing and a triggering mechanism can enter the area, it will be an active day especially in the slight risk portion of the severe weather potential

SKYWARN Self-Activation with Amateur Radio Call-Up Nets will monitor the severe weather potential for Sunday Afternoon and evening and Monday Afternoon and Evening. Pictures and videos of storm damage from the events over the next couple days or prior events in the previous two days can be sent as a reply to this message, via our WX1BOX Facebook and Twitter feeds and to the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated.

Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms are possible particularly in Western Massachusetts and Western Connecticut though all interior Southern New England should monitor the potential this Saturday Afternoon and Evening between 4-11 PM. Strong to damaging winds, hail, frequent lightning and heavy downpours leading to urban and poor drainage flooding are the main threats.
..The Storm Prediction Center (SPC) has placed portions of Western Massachusetts and Western Connecticut in a marginal risk for severe weather..
..A Heat Advisory is also in effect until 7 PM Saturday Evening for Northern Connecticut, Providence, Kent Counties of Rhode Island, Southern Worcester, Essex, Central and Southeast Middlesex, Suffolk, Norfolk, Bristol and Plymouth Counties of Massachusetts for hear indices of 95 to 104 degrees. If outdoors, take frequent breaks if working, drink plenty of liquids and find cool areas to rest to avoid heat related illnesses..
..SKYWARN Self-Activation will monitor the severe weather potential for later Saturday PM and evening..

Yesterday, severe weather affected portions of Southern New England. Hardest hit was the Simsbury, Granby, West Suffield, CT area along with East Windsor CT. Other isolated damage were reported in parts of Western, Central and Eastern Massachusetts and Northeast Rhode Island. The WX1BOX Amateur Radio log and NWS Norton Local Storm Report are listed below:

NWS Norton MA Local Storm Report:
https://wx1box.org/wp-content/uploads/2024/08/LSR-8-2-24.pdf

Today could have a similar scenario as Friday though a bit later in the day after 4 PM through 11 PM this Saturday Afternoon and Evening. The headlines depict current thinking. Key factors include:

1.) Ability of heating and destabilization and marginal wind shear to compensate for other marginal instability factors to produce severe weather
2.) Timing of an impulse in atmosphere to trigger the instability and marginal wind shear for strong to severe thunderstorm development

Hello to all…

The 2024 Northeast HamXposition and ARRL New England Division Convention will be held from Thursday Evening 8/22/24-Sunday 8/25/24. There will be many interesting forums at this year’s convention. For complete information on this Amateur Radio Convention, please see the following link:
https://hamxposition.org/

We will have a SKYWARN/ARES/RACES table at the Convention as we have had going back to the late 1990s. In addition, there will be several SKYWARN and weather related topics including SKYWARN Training which will be taught by NWS Boston/Norton by recently named Warning Coordination Meteorologist, Frank Nocera and KD1CY-Rob Macedo, Eastern Mass ARES SEC & SKYWARN Coordinator and a perspective on 30 years of NWS-ARRL ARES partnership with Taunton/Norton Office by retired Warning Coordination Meteorologist, KB1GHX-Glenn Field.

The Convention is also honored and privileged that Matt and Danielle Noyes from their new digital weather venture, 1Degree Outside. They will be presenting about their new venture and the vital role Amateur Radio & non-Amateur Radio SKYWARN Spotters play with surface reporting during severe weather events and immediately following their presentation will be an Advanced Topics in SKYWARN Presentation combining Doppler Radar Fundamentals and understanding with how to gather critical surface and damage reporting via various techniques utilized within the SKYWARN and Amateur Radio communities during severe weather.

A list of the key SKYWARN and weather related presentations for Northeast HamXposition are listed below:

Friday 8/23/24:
100 PM: NWS SKYWARN and ARRL ARES: 30 Years of Support and Partnership in New England by KB1GHX-Glenn Field, retired NWS Boston/Norton WCM
300 PM: SKYWARN Spotter training by NWS Norton Warning Coordination Meteorologist Frank Nocera and KD1CY-Rob Macedo

Saturday 8/24/24:
100 PM: 1DegreeOutside: A Digital-First Weather Approach and the Vital Role of SKYWARN Spotters by Matt & Danielle Noyes
200 PM: Advanced Topics in SKYWARN – Doppler Radar Fundamentals & How You Can Help with Severe Weather Reporting Situational Awareness by KD1CY-Rob Macedo

There are many other topics related to ARES and Emergency Communications at the convention including presentations from the FEMA Region 1 Disaster Communications department. The full schedule of presentations can be seen here:
https://registration.hamxposition.org/Schedule/

The Convention also features a full Amateur Radio Flea Market and Amateur Radio vendors. For those that maybe interested in getting their Amateur Radio license, the convention has a “Tech in a Day” class on Saturday 8/24/24 and several Volunteer Examiner (VE) test sessions as listed on the schedule.

We hope many from the Amateur Radio community and even those outside of the Amateur Radio community can attend and see the SKYWARN/Weather related presentations and for those that might be interested in getting their Amateur Radio license, use the convention as an opportunity to get licensed by preparing ahead of time or take advantage of the Tech-In-A-Day licensing class offered. Thanks to all for their support!

Hello to all…

..Isolated strong to severe thunderstorms and localized flooding of urban and poor drainage areas are possible over Cape Cod and the Islands potentially expanding elsewhere across Southeast New England from roughly Westerly to Providence to Newport and points east for overnight into early to mid Tuesday AM between 4-10 AM. Urban and poor drainage flooding is the primary threat but a secondary threat for localized wind damage or an isolated brief tornado and/or waterspout is a secondary threat..
..The key factors in this event is how far north rain and thunderstorms make it into the region. It could be centered over Cape Cod and the Islands, be further south across the islands or south of the islands or trend further north into the Westerly to Providence through Southeast Mass region. This will be monitored closely as the trend has been further north with this activity..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible early Tuesday AM for wind damage, flooding, rain gauge reports 1″ or more etc. depending on the track of this activity. This will be the only coordination message on this potential system for Southeast New England. Below are the NWS Boston/Norton Area Forecast Discussion and Enhanced Hazardous Weather Outlook..

Hello to all…

Please propagate widely to folks and we have posted this message at the top of our wx1box.org web site.

We have continued to receive a number of questions and problems with regard to our SKYWARN Announcement email list within the last few weeks and we wanted to provide an additional update. As stated previously, over the last year, we have had chronic email server issues with the SKYWARN Announcement list due to new spam prevention techniques launched by some of the larger email providers. At first, it was just Microsoft email addresses but it has now spread to Comcast and some gmail users as well.

Our email administrator, Phil McNamara, is looking to address the issue with a new email server that will have new hardware and software that should fix it completely by the end of September 2024. It has taken longer than expected due to unexpected technical glitches and vacation time of a key professional resource that has been assisting on the new email server software and hardware installation.  We are sorry for the issues this causes you or others that are on the announcement email list that haven’t been receiving messages and how its extended into September. All our coordination messages for severe weather are posted via https://www.wx1box.org and via our Facebook and Twitter feeds under WX1BOX on social media until we address the email issues being seen and this has been a standard protocol for years so please look to these sources if you don’t see emails regarding severe weather potential until this problem is addressed.

We appreciate your understanding during this time and we will send an updated message once the enhancements are completed. Thanks to all for your support of the NWS Boston/Norton SKYWARN program and your support of Amateur Radio!

Hello to all…

..Widespread severe weather event across Western, North-Central and Northeast Massachusetts caused just over 30,000 customers to lose power in Massachusetts at the height of the severe weather with more isolated activity in Northern Connecticut occurred on Tuesday 7/16/24. Any post storm damage reports, pictures, videos from this event welcome..
..Isolated to Scattered Strong to Severe Thunderstorms likely across much of Western and Central Massachusetts and Connecticut possibly extending to the rest of Southern New England this Wednesday Afternoon and Evening between 4-10 PM EDT. Strong to damaging winds, hail, frequent lightning and heavy downpours leading to urban and poor drainage flooding are the main threats.
..The Storm Prediction Center (SPC) has Western and Central Massachusetts, Connecticut into extreme Northwest Rhode Island in a slight risk for severe weather with with a marginal risk for severe weather for the rest of Southern New England..
..Intense heat and humidity with a heat wave continues Wednesday and will end today. A Heat Advisory is now in effect through 8 PM Wednesday Evening for Eastern Franklin, Worcester, Middlesex, Essex, Eastern Hampshire, Eastern Hampden, Norfolk, Bristol, Plymouth Counties of Massachusetts, Northern Connecticut, Rhode Island except for Block Island for heat indices up to 101 expected. Drink plenty of liquids and seek cooler air conditioned areas as needed during the heat wave..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets will be done as needed for severe weather potential Wednesday Afternoon and Evening as needed. Pictures and videos of storm damage, hail, flooding, etc. from the prior events on Monday and Tuesday and anything that occurs on Wednesday can be sent as a reply to this email, via our WX1BOX Facebook/Twitter feeds or the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated..

A heat wave started Monday in much of Southern New England and along with the heat wave, widespread severe weather event across Western, North-Central and Northeast Massachusetts caused just over 30,000 customers to lose power in Massachusetts at the height of the severe weather with more isolated activity in Northern Connecticut occurred on Tuesday 7/16/24. Isolated strong to severe thunderstorms impacted portions of Western Massachusetts and the area from Hingham to Cohasset Mass on Monday 7/15/24. Any post storm damage reports, pictures, videos from these events welcome. The WX1BOX Amateur Radio Log and NWS Boston/Norton Local Storm Reports from Tuesday and Monday are listed below:

The heat wave continues through Wednesday along with a final round of isolated to scattered strong to severe thunderstorm potential for Wednesday as a cold front will move through bringing an end to the heat wave starting Thursday. The headlines depict the current thinking. Key factors for Wednesday include:

1.) Timing of the cold front and thunderstorms to move in close enough to max heating to take advantage of high levels of instability.
2.) Ability for the complex of strong to severe thunderstorms to sustain itself if it arrives later in the evening.
3.) Whether certain limiting instability factors can be overcome by other more favorable instability parameters similar to Monday.
4.) Level of wind shear is a bit less than the minimal criteria for severe thunderstorm development but may be overcome by factors 1-3.

SKYWARN Self-Activation with Amateur Radio Call-Up Nets will be done as needed for severe weather potential Wednesday Afternoon and Evening as needed. Pictures and videos of storm damage, hail, flooding, etc. from the prior events on Monday and Tuesday and anything that occurs on Wednesday can be sent as a reply to this email, via our WX1BOX Facebook/Twitter feeds or the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated. This will be the last severe weather coordination message as we shift into operations mode and a post severe weather coordination message or messages from prior significant severe weather events will be posted by the end of the weekend.

Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms possible across much of Western and Central Massachusetts and Connecticut possibly into Northwest Rhode Island Tuesday Afternoon and Evening between 2-10 PM EDT with the latter half of the time range the most likely time for severe weather potential. Strong to damaging winds, hail, frequent lightning and heavy downpours leading to urban and poor drainage flooding are the main threats.
..The Storm Prediction Center (SPC) has Western and Central Massachusetts, Connecticut into extreme Northwest Rhode Island in a marginal to slight risk for severe weather with the higher slight risk area further west into Western Massachusetts and Northwest Connecticut for Tuesday. An enhanced risk for severe weather is just northeast of the Western Massachusetts border into Northeast New York and Southern Vermont for Tuesday as well.
..There is an additional chance for severe weather Wednesday Afternoon and Evening between 1-11 PM EDT as a cold front will bring an end to the heat wave. SPC has a slight risk for severe weather in Western Massachusetts and Western Connecticut with a marginal risk for severe weather across the west of Southern New England.

A heat wave started Monday in much of Southern New England and along with the heat wave, isolated strong to severe thunderstorms impacted portions of Western Massachusetts and the area from Hingham to Cohasset Mass. The WX1BOX Amateur Radio Log and NWS Boston/Norton Local Storm Reports are listed below:

The heat wave continues through Wednesday along with the potential for isolated to scattered strong to severe thunderstorm potential for Tuesday, particularly in Western and Central Southern New England and for much of Southern New England on Wednesday. The headlines depict the current thinking. Key factors for Tuesday include:

1.) A complex of strong to severe thunderstorms known as a Mesoscale Convective Vortex or MCV will be moving through Southern Ontario Canada into Western, Central and Eastern New York during the late morning through late afternoon. The timing of this complex of the strong to severe thunderstorms into our coverage area or if strong to severe thunderstorms form out ahead of the complex in western parts of our coverage area near or just past the time of peak heating will determine coverage of isolated to scattered severe thunderstorms in our area.
2.) Ability for the complex of strong to severe thunderstorms to sustain itself if it arrives later in the evening.
3.) Whether certain limiting instability factors can be overcome by other more favorable instability parameters similar to Monday.
4.) Level of wind shear is a bit less than the minimal criteria for severe thunderstorm development but may be overcome by factors 1-3.

The additional severe weather potential for Wednesday will be covered in future coordination messages most likely Wednesday Morning. The headlines give quick details on Wednesday’s potential as a cold front will end the heat wave over the region.

SKYWARN Self-Activation with Amateur Radio Call-Up Nets will be done as needed for severe weather potential Tuesday Afternoon and Evening and Wednesday Afternoon and Evening as needed. This will be the only coordination message on Tuesday’s severe weather potential and a message on Wednesday’s severe weather potential will be posted by 1130 AM Wednesday Morning. Pictures and videos of storm damage, hail, flooding, etc. can be sent as a reply to this email, via our WX1BOX Facebook/Twitter feeds or the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated.
