Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms are possible across interior Southern New England Tuesday Afternoon and Evening. Strong to damaging winds, hail, frequent lightning and heavy rainfall leading to urban and poor drainage flooding are the primary threats. Timeframe would be any time between 3-10 PM Tuesday.
..The Storm Prediction Center (SPC) has expanded the slight risk for severe weather area into Western and Central Massachusetts and into Northwest and North Central Connecticut from roughly Tyngsboro, through Worcester Massachusetts and Vernon, Connecticut west with a marginal risk for severe weather east of the Tyngsboro-Worcester-Vernon line to the Boston to Providence I-95 corridor of Eastern Massachusetts and Northwest Rhode Island..
..SKYWARN Self-Activation will monitor the severe weather potential for Tuesday Afternoon and Evening..

Heat and humidity will build into the region on Tuesday ahead of a cold front that will sweep through Southern New England Tuesday Afternoon and Evening. The headlines depict the current thinking which expands the highest severe weather potential into portions of North-Central Connecticut and Central Massachusetts. Key factors for the severe weather potential Tuesday remain:

1.) Amount of heating and destabilization ahead of any late Tuesday morning/early afternoon convection that may impact parts of the region.
2.) Amount of moisture that returns after any morning convection. Models show drying in the atmosphere during the afternoon with some moisture return towards late Tuesday Afternoon and Evening. If this moisture return can occur not too far past the time of peak heating, it will increase the severe weather potential. If the moisture return is too late, severe weather potential will be reduced with most thunderstorms being non-severe in nature later Tuesday Evening.
3.) Amount of forcing with the front and how quickly it moves in for the front to tap into sufficient wind shear profiles and expected moderate instability levels.

SKYWARN Self-Activation will monitor the severe weather potential for Tuesday Afternoon and Evening. This will be the last coordination message as we shift into operations mode. Below is the NWS Boston/Norton Area Forecast Discussion, Hazardous Weather Outlook and SPC Day-1 Convective Outlook:

Hello to all…

..Isolated to scattered strong to severe thunderstorms remain likely Saturday Afternoon and Evening across much of Southern New England with strong to damaging winds, hail, frequent lightning and heavy rainfall leading to potential urban and poor drainage flooding as the main threats. The Storm Prediction Center (SPC) has continued much of Southern New England in a Slight Risk for severe weather except for Southeast Coastal Massachusetts and Newport County Rhode Island which are under a marginal risk for severe weather for Saturday. Timeframe is between 2-8 PM give or take 1-2 hours..
..SKYWARN Self-Activation is likely Saturday Afternoon and Evening to monitor this severe weather potential..

Overnight, clusters of strong and a couple isolated severe thunderstorms occurred in the region overnight and were still ongoing in Southeast New England with an area of showers across Southeast New York, Northern Connecticut and into Northwest and North-Central Massachusetts. This area will move through during the late morning and early afternoon hours and behind it will be some clearing and destabilization that will set the stage for a potentially active severe weather day that remains likely on Saturday Afternoon and Evening with the potential for isolated to scattered strong to severe thunderstorms in clusters or line segments to affected much of Southern New England Saturday Afternoon and Evening. There has been little change to the ongoing forecast based on the current model runs.

As is the case with strong to severe thunderstorms, not every location, city or town will see this activity but isolated to scattered pockets of strong to severe thunderstorms will affect the region as a cold front brings an end to intense heat and humidity to the region. Conditions will dry out late Saturday Night into Sunday Morning from northwest to southeast allowing for nice summer weather for July 4th long weekend activities from Sunday Afternoon through Monday Evening. The headlines depict the current thinking. Key factors remain:

1.) There continues to be some shower and thunderstorm activity this Saturday Morning which should clear out from the area in the late morning and early afternoon hours per radar and satellite imagery. The amount of clearing to allow for more intense destabilization after this activity moves through will be a key factor in determining the extent of strong to severe thunderstorms during the time of peak heating Saturday Afternoon and Evening.
2.) If there is strong clearing with the favorable wind shear profiles in place, this could allow for more a potent severe weather event across the region and this will be monitored.

SKYWARN Self-Activation is likely Saturday Afternoon and Evening to monitor this severe weather potential. This will be the last coordination message as we shift further into operations mode as we have been active during the overnight and early morning period.

Hello to all…

..Isolated Strong to Severe Thunderstorms are possible late Wednesday Afternoon and Evening across Western Massachusetts between 4-10 PM today. Strong to damaging winds, hail, frequent lightning and heavy rainfall leading to brief urban and poor drainage flooding are the main threats. The Storm Prediction Center (SPC) has placed Western Massachusetts and points north into Northern New York and Northern New England..
..Key factors in any severe weather potential for Western Massachusetts will be amount of moisture and instability that develops in the area and how far south any thunderstorm activity develops and if it gets into Western Massachusetts or stays north of this area..
..SKYWARN Self-Activation will monitor the severe weather potential for Western Massachusetts late Wednesday Afternoon and Evening. This will be the only coordination message on this severe weather potential. Below is the NWS Boston/Norton Area Forecast Discussion and SPC Day-1 Convective Outlook..

Hello to all..

..The following is the second and final 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 19 years for Amateur Radio Operators involved with Field Day and the NWS Boston/Norton SKYWARN Program..
..2022 Field Day weekend will mostly be dry, warm and humid. There is a chance of an isolated shower on Friday for Field Day sites setting up on Friday. The weekend looks dry and the threat for any thunderstorms during the course of Field Day weekend is near zero at this time with high temperatures Friday through Sunday in the 80s to lower 90s (70s to lower 80s at the coast) and lows in the 60s. Shower and thunderstorm chances will increase as we get into Monday from west to east across Southern New England but this is after the Field Day weekend event is completed as well as any takedown of sites typically done late Sunday Afternoon and early evening..
..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. Amateur Radio Field Day sites will likely be operating under normal conditions pre-pandemic across most field day sites though it is possible some Field Day sites may have some minimal COVID-19 protocols in place. There will likely still be some home station Field Day sites but less than the prior 2 years during the pandemic with more traditional Field Day sites in the region..
..SKYWARN Self-Activation will monitor conditions throughout Field Day weekend as needed though no activations are expected at this time..

Here are some links to information on these Amateur Radio Field Day Sites from across the region. Again most will likely be operating normally but there could be some minimal COVID-19 protocols in place at certain locations:

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

Similar to last year, Amateur Radio Field Day is expected to feature warm and dry conditions across the region. An isolated shower could occur in parts of Southern New England on Friday for Amateur Radio Field Day sites setting up Friday but its likely to be very isolated. The weekend looks dry and no thunderstorms are expected in the region until post the Field Day event on Monday. High temperatures Friday through Sunday will be in the 80s to lower 90s with upper 70s to lower 80s near the coast and lows will be in the 60s. Humidity levels are expected to be fairly high in the region with Sunday being the hottest and most humid day in the region. All involved in Field Day sites are asked to use caution with the heat, take breaks during setup and breakdown of Field Day sites, and drink plenty of uncaffienated liquids to stay hydrated.

Below are links to the NWS Boston/Norton Hazardous Weather Outlook and NWS Boston/Norton Enhanced Hazardous Weather Outlook:

Amateur Radio Field Day sites are 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 if any threat for thunderstorms develops though that is expected to be minimal this year. 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. The link below features information on Heat Safety:
https://www.weather.gov/safety/heat

While the thunderstorm threat is near zero this weekend, now is the time to remind folks that 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 and we have also added a link from this week’s NWS Boston/Norton Lightning Safety Awareness Week and Public Information Statements on Lightning Safety. See links below:
https://www.weather.gov/safety/lightning
https://wx1box.org/wp-content/uploads/2022/06/lightning_safety_awareness_PNS_2022.pdf

This will be the last coordination message for Amateur Radio Field Day weekend given no significant risk for thunderstorm activity. We hope the Amateur Radio community participating in Field Day has a great weekend!

Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms remain possible Friday Afternoon and Evening anytime between 12-6 PM across all of Southern New England with interior Southern New England the favored area of the region. Strong to damaging winds, hail, frequent lightning and heavy downpours with urban and poor drainage flooding are the main threats. The Storm Prediction Center (SPC) has continued much of Southern New England in a Marginal Risk for severe weather though dropped the mention of an upgrade to slight risk..
..SKYWARN Self-Activation will monitor the severe weather potential for Friday Afternoon and Evening..

Severe weather is possible ahead of a cold front that will bring much cooler air into the region after the heat and humidity on Friday. The headlines depict the current thinking. Key factors include:

1.) Any cloud cover or residual shower and thunderstorm activity overnight/early morning and how that affects heating. Satellite imagery shows clearing across Western and Northern Massachusetts spreading its way south and east through the region which should allow for isolated to scattered strong to severe thunderstorm development.
2.) The mid-levels of the atmosphere will dry out some and if they dry out too much that could limit the coverage/intensity of strong to severe thunderstorms. At this time, its expected there will be sufficient moisture for isolated to scattered strong to severe thunderstorms given the strong shear in the atmosphere and clearing allowing for destabilization
3.) Timing of the cold front which is currently expected to be at reasonable time for peak heating and destabilization particularly for central and eastern portions of the marginal severe weather risk area.
4.) If key factors 1 an 2 line up to allow for greater instability and more moist mid-levels of the atmosphere, the severe weather potential would be more robust but current modeling has a more isolated to scattered nature to the strong to severe thunderstorm potential but this will be monitored through the day.

SKYWARN Self-Activation will monitor the severe weather potential for Friday Afternoon and Evening. This will be the last coordination message as we shift into operations mode. Below is the NWS Boston/Norton Area Forecast Discussion and SPC Day-1 Convective Outlook:

Severe weather is possible ahead of a cold front that will bring much cooler air into the region after the heat and humidity on Friday. The headlines depict the current thinking. Key factors include:

1.) Any cloud cover or residual shower and thunderstorm activity overnight/early morning and how that affects heating. If the day starts out with clear/sunny conditions or rapid clearing occurs in the wake of any overnight or early morning activity, this could increase the severe thunderstorm potential.
2.) The mid-levels of the atmosphere will dry out some and if they dry out too much that could limit the coverage/intensity of strong to severe thunderstorms. Recent model runs have actually increased the mid-level moisture and if that occurs that could mean a reasonable coverage of strong to severe thunderstorms.
3.) Timing of the cold front which is currently expected to be at reasonable time for peak heating and destabilization particularly for central and eastern portions of the marginal severe weather risk area.
