SPC has continued the enhanced risk for severe weather with a slight eastward expansion in the latest update across Western Massachusetts and North-Central Connecticut. The severe weather potential exists through Central Massachusetts and Northeast Connecticut where a slight risk of severe weather is in place but less than areas to the west with the strong to severe thunderstorm potential waning as you get further east due to time of day and more of a marine influence particularly in Southeast New England. While there are some severe weather parameters that are unfavorable, there appears to be the right combination of parameters including high dewpoints, sufficient heating for destabilization. sufficiently strong wind shear profiles and timing and forcing of the cold front that warrants the current enhanced and slight risk areas. The headlines of the coordination message continue to capture things well. The key factors as mentioned in prior messages will determine the coverage of the severe weather and flash flood potential and include:<br><br>1.) Sunshine for expected heating and destabilization occurs as expected.<br>2.) Timing of the cold front is near the favorable timeframe for peak heating.<br>3.)
The forcing of the cold front, high dewpoints and favorably strong wind
shear offset other unfavorable parameters for severe weather.<br><br>SKYWARN
Activation with Ops at NWS Taunton will commence by 1 PM EDT <span class="Object" id="OBJ_PREFIX_DWT85_com_zimbra_date">Monday</span> for
severe weather potential. This will be the last coordination message as we shift into Amateur Radio Operations mode. Below is the NWS Taunton Flash
