Severe Weather Coordination Message #2 – Monday 7/22/19 – Severe Weather/Flash Flood Potential

Hello to all…

..Isolated to Scattered strong to severe thunderstorms likely particularly in areas of Connecticut and Rhode Island and could extend into Southeast Massachusetts where the Storm Prediction Center (SPC) has a slight risk for severe weather and outside of the slight risk area, there is a marginal risk for severe weather across much of the rest of Massachusetts for Monday Afternoon and Evening. Strong to damaging winds, frequent lightning and heavy rainfall with urban and poor drainage flooding to flash flooding are the primary threats but there is also a secondary threat for hail and an isolated tornado..
..A Severe Thunderstorm Watch is now in effect through 1000 PM Monday Evening for Connecticut and Rhode Island as this is the best area for severe thunderstorm development but areas around the severe thunderstorm watch in Massachusetts should also closely monitor the severe weather potential..
..SKYWARN Activation with Ops at NWS Boston/Norton will commence by 6 PM EDT Monday Evening lasting through late evening. This will be the last coordination message on the severe weather and flash flood potential. Below is the SPC Severe Thunderstorm Watch Statement, Hazardous Weather Outlook, Enhanced Hazardous Weather Outlook and SPC Day-1 Convective Outlook…
