Storm Coordination Message #1 – Saturday 5/30/26 Strong to Damaging Wind & Other Hazards Potential

May 29, 2026 Rob Macedo

Hello to all…

..Unusually strong upper level low pressure system will bring the potential for strong to damaging winds, possibility for thunderstorms that could enhance wind damage potential and produce hail, pockets of heavier rainfall and even the possibility of non-accumulating wet snow to the highest elevations of portions of interior Southern New England on Saturday..
..A High Wind Warning is now in effect from 8 AM to 8 PM Saturday for Cape Cod and Nantucket for sustained winds of 25-35 MPH with gusts to 65 MPH expected. A Wind Advisory is now in effect from 8 AM to 8 PM Saturday for all of Rhode Island, Central and the remainder of Eastern Massachusetts for sustained winds of 20-35 MPH with gusts to 55 MPH expected. Isolated higher wind gusts are possible in the warning/advisory areas and these winds could cause scattered pockets of tree, wire damage and power outages..
..SKYWARN Self-Activation likely with Amateur Radio Call-Up Nets possible in the High Wind Warning/Wind Advisory areas and for any thunderstorm activity for stronger winds and hail, rainfall and any higher elevation wet snowfall reports on Saturday. 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..

A unusually strong upper level low pressure system will be bringing strong to damaging winds, thunderstorms that may enhance strong to damaging wind potential along with hail and even the potential for non-accumulating wet snow in the higher elevations of Southern New England. The headlines depict the current thinking. Key factors include:

1.) Ability of strong winds in the lowest level of the atmosphere to mix down to the surface.
2.) The position of the strongest winds. Currently the advisory and warnings as they are placed represent where the strongest winds will be and their coverage but this could slight a bit west or a bit east depending on the track of the upper level low.
3.) With an unusually dynamic upper level low for this time of year, will need to monitor for unexpected increases in strength of the winds, thunderstorm activity and perhaps even non-accumulating snow in the higher elevations of interior Southern New England.

May 19, 2026 Rob Macedo

Hello to all…

..Intense Heat & Humidity will set the stage for isolated to scattered strong to severe thunderstorms across portions of interior Southern New England Tuesday Afternoon into Tuesday Evening between 3-8 PM with perhaps a greater threat for severe thunderstorms over much of the region Wednesday Afternoon and evening between 2-8 PM as a strong cold front moves through the area Wednesday..
..The Storm Prediction Center (SPC) has continued most of Southern New England north and west of the I-95 corridor in a marginal risk for severe weather Tuesday and pretty much all of Southern New England in a marginal risk for severe weather for Wednesday. Strong to damaging winds, hail, frequent lighting and heavy downpours leading to urban and poor drainage flooding are the main threats..
..A Heat Advisory remains in effect through 8 PM Wednesday Evening for Providence, Kent Counties of Rhode Island, Northern Connecticut, Eastern Franklin, Eastern Hampshire, Eastern Hampden, Worcester, Middlesex, Essex, Norfolk, North-Central Bristol and North-Central Plymouth Counties of Massachusetts for heat indices of 96. Areas outside of the head advisory away from the coast will be hot and humid but below heat advisory criteria. All areas people working outdoors should drink plenty of liquids, take frequent breaks and people in the heat should seek cooler areas as needed..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets remain possible Tuesday Afternoon and Evening and Wednesday Afternoon and Evening for severe weather potential if a severe thunderstorm warning is issued for a given area. Another coordination message on the Wednesday severe weather potential will be posted by 11 AM Wednesday AM. 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.

Wind Coordination Message #1 – Monday 5/4/26 – Strong Wind Gust/Isolated Wind Damage Potential

May 5, 2026 Rob Macedo

Hello to all…

..Strong Wind Gusts likely across portions of Rhode Island and Eastern Massachusetts late Tuesday AM to Tuesday Evening. Also, while the main threat for severe thunderstorms will be across Northern New England, an isolated strong to severe thunderstorm with strong to damaging winds, hail, frequent lightning and heavy rainfall can’t be ruled out for portions of Northwest Massachusetts..
..A Wind Advisory is in effect from 12 PM to 10 PM Tuesday for Essex, Central and Southeast Middlesex, Suffolk, Norfolk, Bristol, Plymouth Counties of Massachusetts and all of Rhode Island except Northwest Providence County RI and Block Island RI for sustained winds of 15-30 MPH with gusts up to 50 MPH. Areas outside of the Wind Advisory could see wind gusts around 40 MPH. These winds could cause isolated pockets of tree, wire damage and power outages..
..SKYWARN Self-Activation will monitor the strong wind gusts and isolated wind damage potential across the entire area and any isolated severe weather potential for Northwest Massachusetts. This will be the only coordination message for this event unless a significant upgrade to the situation occurs and time allows for an update. Below is the NWS Boston/Norton Wind Advisory Statement, Area Forecast Discussion and Enhanced Hazardous Weather Outlook..
