Severe Weather Coordination Message #2 – Late Saturday PM & Evening Saturday 6/6/26 Severe Weather Potential
Hello to all…
..Slight changes to timing but no major changes to severe weather potential for late Saturday PM and evening..
..Intense Heat & Humidity will set the stage for isolated to scattered strong to severe thunderstorms across portions of Southern New England late Saturday Afternoon into Saturday Evening between 4 PM-11 PM, possibly 1-2 hours later in southeast parts of the area as an impulse and cold front swing through the area..
..The Storm Prediction Center (SPC) has continued most of Southern New England north and west of the I-495 corridor in a slight risk for severe weather with the rest of Southern New England in a marginal risk for severe weather. Strong to damaging winds, hail, frequent lighting and heavy downpours leading to urban and poor drainage flooding are the main threats..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible late Saturday Afternoon and Evening for severe weather potential if a severe thunderstorm warning is issued for a given area. 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 late Saturday PM and Evening. Key factors include:
1.) There is the possibility of two rounds of severe weather potential, one between 4-6 PM and the other between 6-9 PM possibly extending into late evening through around 1 AM in portions of Southeast New England. How this evolves will determine length and severity of the severe weather potential.
2.) Later timing would typically mean less risk for severe weather but some instability parameters are present that aren’t not normally there for later evening severe weather potential and this may allow for convection to remain strong to severe even after sunset.
SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible late Saturday Afternoon and Evening for severe weather potential if a severe thunderstorm warning is issued for a given area. This will likely be the last coordination message as we shift into operations mode. 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.
