Severe Weather & Amateur Radio Field Day Weekend Coordination Message #2 – Friday PM/Evening 6/26/26 Thru Sunday Evening 6/28/26

June 26, 2026 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 25 years for Amateur Radio Operators involved with Field Day and the NWS Boston/Norton SKYWARN Program..
..For 2026, Amateur Radio Field Day Weekend will feature a threat of severe weather for any Amateur Radio Field Day sites setting up Friday Afternoon and Evening from 3-11 PM with the highest risk in that timeframe between 5-9 PM particularly in interior Southern New England and the Storm Prediction Center (SPC) has kept a marginal risk for severe weather for Friday PM and Evening across interior Massachusetts along and north of the Mass Pike into New Hampshire but areas of Northern Connecticut and Northern Rhode Island should also monitor. Strong to damaging winds, hail, frequent lightning, and heavy downpours leading to urban and poor drainage flooding are the main threats. Friday Morning has had some showers move through interior Southern New England with a few showers lingering along South Coastal Massachusetts and Rhode Island..
..Saturday Morning continues to have a risk of some showers along and south of the Mass Pike with the greatest risk across South Coastal Massachusetts and Rhode Island followed by clearing conditions and relatively pleasant, warm, sunny, summer weather from Saturday Afternoon through Sunday Evening..
..We will not see extreme heat Friday or this weekend but it will be typical summer-like warmth so as always staying hydrated and taking occasional breaks from strenuous activities is still advised particularly for this weekend..
..Any thunderstorms have lightning potential which is a safety hazard for all Amateur Radio Field Day sites. Amateur Radio Field Day sites are encouraged to guard their local Amateur Radio SKYWARN frequency and have multiple ways to receive weather alerts during the course of this Field Day weekend including by cell phone/Internet and NOAA Weather Radio particularly for sites setting up Friday PM and 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..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible for Friday PM and Evening. Pictures and videos of wind damage, hail, flooding etc. can be sent as a reply to this email, via our Facebook/X/Bluesky feeds or the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated. At this time, there does not appear to be a need for any type of SKYWARN Self-Activation or Amateur Radio Call-Up Nets for Saturday or Sunday..

Here are some links to information on these Amateur Radio Field Day Sites from across the region.

This year’s Amateur Radio Field Day Weekend features a threat for severe weather for any Field Day sites setting up Friday Afternoon and Evening. Friday Morning had showers move through interior Southern New England with a few showers lingering across South Coastal Massachusetts and Rhode Island. The headlines depict the thinking on Friday’s weather. Key factors include:

1.) If sufficient clearing and destabilization allows for sufficient instability to take advantage of strong wind shear profiles to produce severe weather. Satellite imagery shows breaks in the clouds across New York and portions of interior Massachusetts and those continue to expand so instability parameters as modeled look likely to verify if these breaks in the clouds continue based on current trends.
2.) If instability remains limited, whether the strong wind shear profiles compensate allowing for potential strong to severe thunderstorm development.
3.) Timing of the cold front that maximizes instability during the afternoon and evening hours.

As the headlines indicate, Saturday Morning continues to have a risk of some showers along and south of the Mass Pike with the greatest risk across South Coastal Massachusetts and Rhode Island followed by clearing conditions and relatively pleasant, warm, sunny, summer weather from Saturday Afternoon through Sunday Evening.

SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible for Friday PM and Evening. Pictures and videos of wind damage, hail, flooding etc. can be sent as a reply to this email, via our Facebook/X/Bluesky feeds or the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated.

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 as there is a threat for thunderstorm development and any thunderstorm can be a threat to the safety of Amateur Radio Field Day sites. 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:

Southern New England SKYWARN Frequency List

With the thunderstorm threat for any Field Day sites setting up Friday Afternoon and Evening, 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 the 2023 NWS Boston/Norton Lightning Safety Awareness Week and Public Information Statements on Lightning Safety and will update with this year’s statements in a future coordination message. See links below:

This year’s Amateur Radio Field Day Weekend features a threat for severe weather for any Field Day sites setting up Friday Afternoon and Evening. Friday Morning could have showers with embedded thunderstorms and attendant lightning risk but the severe weather potential Friday Morning is low for any Field Day sites setting up Friday Morning. The headlines depict the thinking on Friday’s weather. Key factors include:

1.) If sufficient clearing and destabilization allows for sufficient instability to take advantage of strong wind shear profiles to produce severe weather.
2.) If instability remains limited, whether the strong wind shear profiles compensate allowing for potential strong to severe thunderstorm development.
3.) Timing of the cold front that maximizes instability during the afternoon and evening hours.

As the headlines indicate, there could be showers around Saturday Morning along and south of the Mass Pike with cloudiness but conditions should improve Saturday Afternoon with typical summer warmth and dry conditions from Saturday Afternoon into Sunday Evening.

Severe Weather Coordination Message #2 – Thursday 6/18/26 Severe Weather & Strong Wind Gusts Outside of Thunderstorms Potential

June 18, 2026 Rob Macedo

Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms possible Thursday PM and Evening any time between 12 PM to 11 PM with the most likely time between 2-7 PM across all of Southern New England with the greatest threat over Western and Central Massachusetts and Connecticut..
..Strong to damaging winds, hail, frequent lightning and heavy downpours leading to urban and poor drainage flooding are the main threats and an isolated tornado as a secondary threat cannot be ruled out. The Storm Prediction Center has all of Southern New England in a Slight Risk for severe weather Thursday. A Tornado Watch is now in effect through 3 PM for Berkshire County Massachusetts and into Eastern New York and a severe thunderstorm or tornado watch could get expanded east later today..
..In addition, Strong Wind Gusts to around 40 MPH with isolated higher wind gusts are likely Thursday which will have the potential for isolated pockets of tree, wire damage and power outages independent of any strong to severe thunderstorms..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets possible if SKYWARN reportable criteria is met and/or if a severe thunderstorm/tornado warning is issued Thursday PM and Evening. Pictures and videos of wind damage, hail, flooding etc. can be sent as a reply to this email, via our Facebook/X/Bluesky feeds or the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated..

The headlines depict current thinking on severe weather potential for Thursday. Key factors include:
1.) If more instability develops than expected with sunshine and destabilization, strong wind shear profiles could lead to a potentially more significant severe weather threat and this aspect will bear watching. If instability is limited, the severe weather potential will be more muted. Current satellite images show sufficient clearing for destabilization ahead of a line of severe thunderstorms in Central New York and this is expected to propagate eastward.
2.) Very strong wind shear profiles even with more limited instability could lead to a low instability, high shear environment that may allow for damaging wind and severe thunderstorm potential. There is some evidence of this as well with the line of severe thunderstorms in Central New York.
3.) Outside of any strong to severe thunderstorms, given strong low-level wind fields, wind gusts to around 40 MPH with potential for higher wind gusts could lead to isolated pockets of tree, wire damage and power outages.

SKYWARN Self-Activation with Amateur Radio Call-Up Nets possible if SKYWARN reportable criteria is met and/or if a severe thunderstorm warning is issued Thursday PM/Evening. This will be the last coordination message unless a significant change to the situation occurs and time allows for an update. Pictures and videos of wind damage, hail, flooding etc. can be sent as a reply to this email, via our Facebook/X/Bluesky feeds or the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated.

Severe Weather Coordination Message #2 – Sunday Evening 6/14/26 Severe Weather Potential

June 14, 2026 Rob Macedo

Hello to all…

A cold front will have the potential to bring isolated to scattered strong to severe thunderstorms particularly to Connecticut and Western and Central Massachusetts but areas as far east as Rhode Island and interior Southeast Massachusetts should monitor. The headlines depict the current thinking. Key factors include:

1.) Later timing of the cold front and whether there will be sufficient instability despite strong wind shear profiles to allow for strong to severe thunderstorm development or whether strong wind shear compensates for potentially limited instability.
2.) Whether the area of strong to severe thunderstorms “splits” with one area of strong to severe thunderstorms going more into Northern New England and the other remaining south of Southern New England over the Mid-Atlantic states.

SKYWARN Self-Activation with Amateur Radio Call-Up Nets possible if SKYWARN reportable criteria is met and/or if a severe thunderstorm warning is issued Sunday Evening. Pictures and videos of wind damage, hail, flooding etc. can be sent as a reply to this email, via our Facebook/X/Bluesky feeds or the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated.
