Severe Weather Coordination Message #1 – Tuesday 7/6/21 Severe Weather Potential
Hello to all…
..Isolated to Scattered Strong to Severe Thunderstorms are likely Tuesday Afternoon and Evening across Southern New England with strong to damaging winds, hail, frequent lightning and heavy rainfall with urban and poor drainage flooding are the primary threats. The Storm Prediction Center (SPC) has placed all of Southern New England in a Slight risk for severe weather with the timeframe between 1-8 PM Tuesday Afternoon and Evening..
..SKYWARN Self-Activation will monitor the severe weather potential for Tuesday Afternoon and Evening..
Heat and humidity will return to Southern New England Tuesday and with an impulse in the atmosphere, it will set the stage for isolated to scattered strong to severe thunderstorms during the Tuesday afternoon and evening hours. The headlines depict the current thinking. Key factors include:
1.) Wind shear values will be marginally conducive for severe thunderstorms with damaging wind gusts. If that shear becomes stronger, it could potentially mean a greater more widespread severe weather risk and this will be monitored. Certain mid-level instability parameters are also marginally favorable for severe thunderstorm development.
2.) Any cloud cover leftover from any overnight showers or isolated thunderstorms associated with a warm front pushing through the region that will bring in the heat and humidity.
SKYWARN Self-Activation will monitor the severe weather potential for Tuesday Afternoon and Evening. Another coordination message will be posted by 1000 AM Tuesday Morning. Below is the NWS Boston/Norton Area Forecast Discussion, Enhanced Hazardous Weather Outlook and SPC Day-2 Convective Outlook:
