Severe Weather Coordination Message #5 – Sunday 6/30/19 Severe Weather Potential & Saturday 6/29/19 Severe Weather Recap

June 30, 2019 Rob Macedo

Hello to all…

..After a round of severe weather and flooding in parts of Rhode Island, Central and Eastern Massachusetts, Isolated to Scattered strong to severe thunderstorms are possible to likely mid to late Sunday morning into early Sunday Evening across much of Southern New England. Strong to Damaging winds, hail, frequent lightning and heavy rainfall with the potential for urban and poor drainage flooding are the main threats…
..The Storm Prediction Center (SPC) has continued all of Southern New England in a marginal risk for severe weather on Sunday. Timeframe for severe weather is any time from 10 AM-6 PM on Sunday..
..SKYWARN Activation with Ops at NWS Boston/Norton will likely commence by 10 AM Sunday Morning..
..For Western Massachusetts Amateur Radio SKYWARN Spotters, the 146.94-Mount Tom Repeater which is the primary repeater for this area is down. For SKYWARN Operations in Western Massachusetts, please use the 147.000-Granville Repeater PL 127.3 Hz. If that is not reachable from your location, please use the 146.79-Vernon, CT Repeater PL 82.5..

Saturday brought isolated to scattered strong to severe thunderstorms to portions of Rhode Island, Central and Eastern Massachusetts with many reports of hail and large hail and pockets of wind damage in the area.

Any late reports or pictures/videos can be sent as a reply to this email, via our WX1BOX Facebook/Twitter feeds or through the email address pics@nsradio.org with credit given to the spotter or Amateur Radio Operator for the report or pictures/videos.

As we look at Sunday, not much change to what has been outlined in previous messages. Wind shear profiles will start off strong but become less favorable in the region, however, cooling aloft will be more significant and that will increase instability parameters and this along with good moisture will allow for more coverage area of thunderstorms than Saturday and this will potentially allow for another round of isolated to scattered strong to severe thunderstorms. The wind threat for Sunday maybe somewhat reduced but the hail threat will be higher and the cold air aloft may also compensate to a degree for the lack of wind shear. Heavy rain for urban and poor drainage flooding and frequent lightning are also likely. The timing of this activity is still in some flux but activity could be in the mid to late morning around 10 AM through the early evening hours of around 600 PM. While all of Southern New England should monitor today’s weather, central and eastern Southern New England have the highest potential for scattered strong to severe thunderstorms today.

SKYWARN Activation with Ops at NWS Boston/Norton will commence by 10 AM Sunday Morning. This will be the last coordination message on Sunday’s severe weather as we shift into operations mode.

Severe Weather Coordination Message #3 – Saturday 6/29/19-Sunday 6/30/19 Severe Weather Potential

June 29, 2019 Rob Macedo

Hello to all…

..Isolated to Scattered strong to severe thunderstorms remain possible to likely Saturday Afternoon and Evening across much of Southern New England. Strong to Damaging winds, hail, frequent lightning and heavy rainfall with the potential for urban and poor drainage flooding are the main threats. Timeframe is any time between 12-8 PM today..
..The Storm Prediction Center (SPC) has continued most of Southern New England in a slight risk for severe weather and Cape Cod and the Islands in a marginal risk for severe weather for Saturday..
..There is another chance for severe weather for Sunday with risks similar to today though the potential for hail on Sunday could be higher given a cold pool of air aloft in the region. We will get into some details in this message with more details in the Saturday Evening coordination message..
..SKYWARN Activation with Ops at NWS Boston/Norton will commence by 11-1130 AM Saturday Morning. SKYWARN Activation with Ops at NWS Boston/Norton is possible Sunday for the severe weather potential..

..For Western Massachusetts Amateur Radio SKYWARN Spotters, the 146.94-Mount Tom Repeater which is the primary repeater for this area is down. For SKYWARN Operations in Western Massachusetts, please use the 147.000-Granville Repeater PL 127.3 Hz. If that is not reachable from your location, please use the 146.79-Vernon, CT Repeater PL 82.5..

It will potentially be an active weekend for severe weather across Southern New England. An initial round of thunderstorms moved through portions of Central and Eastern Massachusetts this morning. Satellite imagery shows some clearing behind this activity particularly in Connecticut and Southeast New York which will spread through the region later this morning into early afternoon. This is expected to allow the destabilization required for isolated to scattered strong to severe thunderstorms across the slight risk area as depicted by SPC.

For Saturday, the headlines depict the current severe weather potential well. Key factors for Saturday’s severe weather potential and extent of strong to severe thunderstorm coverage remain the following:

1.) Amount of cloud cover over the area as that will determine destabilization and level of instability for the region.
2.) Timing of the cold front through the region.
3.) Favorable factors for severe weather potential include sufficient wind shear profiles and good cooling of the atmosphere aloft along with a strong triggering mechanism with the cold front.

As we look at Sunday, wind shear profiles will become less favorable in the region but cooling aloft will be more significant and that will increase instability parameters. This will potentially allow for another round of isolated to scattered strong to severe thunderstorms. The wind threat for Sunday maybe somewhat reduced but the hail threat will be higher and the cold air aloft may also compensate to a degree for the lack of wind shear. The timing of this activity is still in flux but activity could be in the mid to late morning through early evening hours.

SKYWARN Activation with Ops at NWS Boston/Norton will commence between 11-1130 AM today. SKYWARN Activation with Ops at NWS Boston/Norton are possible again on Sunday. This will be the last coordination message for the Saturday severe weather potential as we move into operations mode. Another coordination message will be posted by 1030 PM Saturday Evening on the Sunday severe weather potential.

Storm Coordination Message #1 – Tuesday 6/25/19 Heavy Rainfall Potential

June 25, 2019 Rob Macedo

Hello to all…

..A storm system moving through the area will have the potential for heavy rain showers and embedded thunderstorms with heavy rainfall that may produce urban and poor drainage flooding in portions of Southern New England. Widespread rainfall of 0.50-1.00″ is expected but a band or localized amounts of 1.5-2.00″ or more is possible. Currently the greatest threat is along or south of the Mass Pike but all parts of the region could have some heavy rainfall potential in localized areas..
..SKYWARN Self-Activation will monitor the heavy rainfall for today. This will be the only coordination message on this potential unless a significant change to the situation occurs. Below is the NWS Boston/Norton Hazardous Weather Outlook, Enhanced Hazardous Weather Outlook..

Severe Weather and Amateur Radio Field Day Coordination Message #3 – Field Day Weekend Weather – Saturday 6/22/19-Sunday 6/23/19

June 22, 2019 Rob Macedo

Hello to all..

..The following is the third in a series of messages on Amateur Radio Field Day Weekend and providing information on the weather during this period. This is a tradition spanning over 16 years for Amateur Radio Operators involved with Field Day and the NWS Boston/Norton SKYWARN Program..
..The Saturday of 2019 Field Day weekend features the increased potential for isolated to scattered gusty rain showers with the potential for small hail in these showers and the potential for isolated strong to possibly even a marginally severe thunderstorm with small to possibly marginally severe hail, strong winds and lightning as potential threats particularly over Central and Eastern New England any time from Noon-7 PM EDT Saturday. While the weather will be dry and pleasant most of the day with temperatures 70-80 and some breezy conditions with gusts up to 25 MPH outside any showers or thunderstorms, Amateur Radio Field Day sites should closely monitor conditions this Saturday Afternoon and Evening for the convective shower and isolated strong thunderstorm potential..
..Sunday looks dry and warm with less wind and temperatures in the 80s and no chance for precipitation..
..Amateur Radio Field Day Weekend is an annual event where Ham Operators across the United States setup at Emergency Operations Centers, field locations, home locations etc. to operate and test their equipment and skills and make as many radio contacts as possible during the weekend. Many locations can be visited by the public and Amateur Radio Field Day can be a form of outreach to Ham and non-Ham Operators. It is also noted that several states have given proclamations to Amateur Radio/Ham Radio Operators for either an ‘Amateur Radio Day or Amateur Radio Week’ during the month of June or an ‘Amateur Radio Month’ for this month. It is both a fun/preparatory event for Ham Radio Operators for Emergency Communications scenarios..
..SKYWARN Self-Activation will monitor the strong to marginally severe thunderstorm potential this Saturday Afternoon and Early Evening with Ops at NWS Boston/Norton possible to monitor and guard Field Day sites. No SKYWARN Activation of any type is expected on Sunday..

There are a large number of Amateur Radio Field Day sites across the NWS Boston/Norton Coverage Area and adjacent NWS Coverage Areas. Here are some links to information on these Amateur Radio Field Day Sites from across the region:

Amateur Radio Field Day Information: http://www.arrl.org/field-day
Amateur Radio Field Day National Locator: http://www.arrl.org/field-day-locator
Eastern Massachusetts Field Day Home Page: https://ema.arrl.org/field-day/
Eastern Massachusetts Field Day Directory: http://ema.arrl.org/field_day/

The commonwealth of Massachusetts has declared this week to be Amateur Radio Week and Governor Baker has proclaimed Saturday June 22nd, 2019 Amateur Radio Day in honor of the ARRL Field Day event. The details can be seen at the following links:
https://ema.arrl.org/2019/06/19/arrl-field-day-is-this-weekend/
https://ema.arrl.org/2019/06/12/triple-play-ma-hams-receive-amateur-radio-proclamations-resolutions-from-house-senate-and-governor/

For Saturday, the potential has increased for convective gusty rain showers with small hail and isolated strong thunderstorms to possibly a marginally severe thunderstorm or two particularly in Central and Eastern New England particularly between 12-7 PM EDT despite low dewpoints and more limited moisture. If a seabreeze front is able to organize in Southeast New England, that could be a further focus for strong to possibly marginally severe thunderstorm potential and will be monitored. While most of the day will be dry with pleasant weather conditions with temperatures from 70-80 degrees expected and some wind outside of showers up to 25 MPH expected, Amateur Radio Field Day sites should be prepared for changeable weather conditions with the gusty rain showers with the potential for small hail and isolated strong thunderstorms to perhaps even a marginally severe thunderstorms or two Saturday Afternoon and Evening. Any thunderstorms will have the potential for small to perhaps marginally severe hail, strong winds and lightning as potential hazards. Amateur Radio Field Day sites should guard local SKYWARN frequencies and monitor NOAA Weather Radio for shower and thunderstorm activity if it gets near or over their local area and assure antenna setups are properly tied off for gusty winds outside of showers of up to 25 MPH and wind gusts higher to around 40 MPH or greater in the presence of any gusty showers or isolated thunderstorms.

On Sunday, warming conditions will occur with temperatures in the 80s in most locations. Conditions will be warm but not humid with dewpoint temperatures in the 50s and light winds and no threat for precipitation.

SKYWARN Self-Activation will monitor the strong to marginally severe thunderstorm potential this Saturday Afternoon and Early Evening with Ops at NWS Boston/Norton possible to monitor and guard Field Day sites. No SKYWARN Activation of any type is expected on Sunday. Below are links to the NWS Boston/Norton Hazardous Weather Outlook and NWS Boston/Norton Experimental Enhanced Hazardous Weather Outlook:

http://kamala.cod.edu/ma/latest.flus41.KBOX.html

NWS Boston/Norton Experimental Enhanced Hazardous Weather Outlook:
https://www.weather.gov/box/ehwo

Amateur Radio Field Day sites are still encouraged to bring a NOAA All-Hazards Weather Radio, monitor various cell phone weather apps where Amateur Operators may have those available and have a dedicated Ham Radio that can monitor their local SKYWARN Frequency for their area as a best safety and preparedness practice. Also sites that have mobile Internet capability can utilize that capability as a way to monitor for weather information. With Mobile Internet capability, utilizing Echolink to monitor the New England Reflector system on Echolink Conference *NEW-ENG3* Node: 9123/IRLP 9123 would be helpful as well. Please see the link below for the latest SKYWARN Frequency information for the region:
https://wx1box.org/southern-new-england-skywarn-frequency-list/

During setup and takedown of Amateur Radio Field Day sites and even while operating, be sure to drink plenty of fluids and eat accordingly. Also having a jacket or sweatshirt during evenings as conditions cool etc. may also be useful while operating this year’s Field Day. The link below features information on Heat Safety:
https://www.weather.gov/safety/heat

Given the threat for thunderstorms particularly on Saturday, lightning is a threat to any and all Amateur Radio Field Day sites. Remember your lightning safety tips and details on lightning safety can be seen at the following link:
https://www.weather.gov/safety/lightning

Given the dry weather expected for Sunday, this will be the last Amateur Radio Field Day Coordination Message for 2019. A shortened coordination message will be posted if time allows and Ops at NWS Boston/Norton are initiated. Good luck to all Amateur Radio Operators participating in 2019 Field Day!

Severe Weather and Amateur Radio Field Day Coordination Message #2 – Field Day Weekend Weather – Saturday 6/22/19-Sunday 6/23/19

June 22, 2019 Rob Macedo

Hello to all..

..The following is the second in a series of messages on Amateur Radio Field Day Weekend and providing information on the weather during this period. This is a tradition spanning over 16 years for Amateur Radio Operators involved with Field Day and the NWS Boston/Norton SKYWARN Program..
..2019 Field Day weekend had showers and heavy downpours Friday Morning from west to east in Southern New England that ended up extending through the afternoon and early evening in Eastern New England. Saturday still features largely dry weather but some breezy conditions with temperatures between 70-80 degrees and the chance of a isolated to scattered gusty showers and an increased chance for a couple to a few strong thunderstorms with the attendant threats of lightning and small hail in addition to strong wind gusts particularly in Eastern New England potentially extending into Central New England. Sunday looks dry and warm with less wind and temperatures in the 80s..
..Amateur Radio Field Day Weekend is an annual event where Ham Operators across the United States setup at Emergency Operations Centers, field locations, home locations etc. to operate and test their equipment and skills and make as many radio contacts as possible during the weekend. Many locations can be visited by the public and Amateur Radio Field Day can be a form of outreach to Ham and non-Ham Operators. It is also noted that several states have given proclamations to Amateur Radio/Ham Radio Operators for either an ‘Amateur Radio Day or Amateur Radio Week’ during the month of June or an ‘Amateur Radio Month’ for this month. It is both a fun/preparatory event for Ham Radio Operators for Emergency Communications scenarios..
..SKYWARN Activation with Ops at NWS Boston/Norton appear unlikely through this timeframe but SKYWARN self-activation will monitor conditions on Saturday as needed..

For Field Day weekend, Friday brought showers from west to east across Southern New England in the morning with additional showers from north-northwest to South-southeast across Eastern New England in the afternoon into the early evening.

On Saturday, pleasant weather conditions with temperatures from 70-80 degrees are expected though there could be some breezy conditions so assuring antennas and portable setups are mounted properly is essential with wind gusts up to 25 MPH expected. The chance of gusty rain showers has increased a bit along with the chance of an isolated strong thunderstorm or two given cold temperatures aloft with warming at the surface. Moisture levels still look fairly dry so it should preclude a large area of thunderstorm coverage but moisture levels now look high enough to allow for more showers and a couple of isolated thunderstorms with an attendant lightning risk, small hail and strong winds particularly in Eastern New England possibly extending into Central New England. The thunderstorm chances will continue to be monitored into the Saturday Morning Field Day update.

On Sunday, warming conditions will occur with temperatures in the 80s in most locations. Conditions will be warm but not humid with dewpoint temperatures in the 50s and light winds.

Coordination messages for Saturday will help better define the outlook for gusty rain showers and the chance for an isolated thunderstorms with lightning, small hail and gusty winds.

Severe Weather & Amateur Radio Field Day Weekend Coordination Message #1 – Field Day Weekend Weather – Friday 6/21/19-Sunday 6/23/19

June 21, 2019 Rob Macedo

Hello to all..

..The following is the first in a series of messages on Amateur Radio Field Day Weekend and providing information on the weather during this period. This is a tradition spanning over 16 years for Amateur Radio Operators involved with Field Day and the NWS Boston/Norton SKYWARN Program..
..2019 Field Day weekend has showers and possibly heavy downpours Friday Morning in Eastern New England but drying out as we go through Friday Afternoon and Evening from west to east with wind gusts in the 25-35 MPH range meaning assuring proper tying down of antennas for Field Day sites. Saturday features largely dry weather but some breezy conditions with temperatures between 75-80 degrees and the chance of a few isolated gusty showers. Thunderstorms aren’t expected at this time but that will be monitored and if more moisture is available, they could occur with a lightning and small hail threat in addition to strong wind gusts. Sunday looks dry and warm with less wind and temperatures in the 80s..
..Amateur Radio Field Day Weekend is an annual event where Ham Operators across the United States setup at Emergency Operations Centers, field locations, home locations etc. to operate and test their equipment and skills and make as many radio contacts as possible during the weekend. Many locations can be visited by the public and Amateur Radio Field Day can be a form of outreach to Ham and non-Ham Operators. It is also noted that several states have given proclamations to Amateur Radio/Ham Radio Operators for either an ‘Amateur Radio Day or Amateur Radio Week’ during the month of June or an ‘Amateur Radio Month’ for this month. It is both a fun/preparatory event for Ham Radio Operators for Emergency Communications scenarios..
..SKYWARN Activation with Ops at NWS Boston/Norton appear unlikely through this timeframe but SKYWARN self-activation will monitor conditions on Friday and Satuday as needed..

For Field Day weekend, weather looks fairly optimal throughout with warming conditions as we go through the weekend. On Friday, there will be the chance of showers throughout the day heaviest in the morning with a drying trend from west to east over the course of the day. Conditions should be reasonable for any Field Day sites setting up Friday Afternoon and Evening but wind gusts of 25-35 MPH are possible which means making sure antennas are tied down and staked off properly given some of the wind gusts.

On Saturday, pleasant weather conditions with temperatures from 75-80 degrees are expected though there could be some breezy conditions so assuring antennas and portable setups are mounted properly is essential. There is also the chance of a few isolated gusty rain showers given cold temperatures aloft with warming at the surface. Moisture levels are dry so it shouldn’t be much more than a few isolated showers but this will be monitored as if there is more moisture available, it could allow for a few more showers and even an isolated thunderstorm with an attendant lightning risk and small hail. The chance of more extensive showers or a thunderstorm looks low at this time due to lack of available moisture but will be monitored in future Field Day updates.

On Sunday, warming conditions will occur with temperatures in the 80s in most locations. Conditions will be warm but not humid with dewpoint temperatures in the 50s and light winds.

Coordination messages later Friday and Saturday will help better define the outlook particularly for Saturday concerning any gusty rain showers and any chance for an isolated thunderstorm with lightning and small hail.
