Severe Weather Coordination Message #1 – Tuesday 7/17/18 Severe Weather/Flash Flood Potential
Hello to all…
..Isolated to Scattered Strong to Severe Thunderstorms are possible to likely across much of Southern New England particularly interior locations for Tuesday Afternoon and Evening. Strong to damaging winds, hail, frequent lightning and heavy rainfall leading to urban and poor drainage flooding to flash flooding are the main threats. The Storm Prediction Center (SPC) has placed much of Southern New England in a marginal to slight risk for severe weather..
..SKYWARN Activation with Ops at NWS Boston/Norton will likely commence by 11 AM Tuesday. This time could be adjusted based on convective trends tomorrow..
A strong cold front will sweep through Southern New England during the day Tuesday through Tuesday Night. Timing of the front looks reasonable to allow for daytime heating and sufficient instability in the region. Wind Shear profiles while slightly marginal look sufficient coupled with dewpoints greater than 70 degrees to bring isolated to scattered strong to severe thunderstorms across much of Southern New England with interior areas favored. The headlines outline the severe weather/flash flood potential. Key factors on the severe weather potential for Tuesday include the following:
1.) Any low clouds/fog or leftover overnight convection cloudiness breaks to allow for sufficient heating and destabilization for expected instability to be realized.
2.) Cold frontal passage timing is at time of peak heating as expected.
SKYWARN Activation with Ops at NWS Boston/Norton will likely commence by 11 AM Tuesday. This time could be adjusted based on convective trends tomorrow. Another coordination message will be posted by 1000 AM Tuesday Morning. Below is the NWS Boston/Norton Hazardous Weather Outlook, Enhanced Hazardous Weather Outlook and SPC Day-2 Convective Outlook:
