Severe Weather Coordination Message #1 – Wednesday 7/25/18 – Severe Weather/Flash Flood Potential

Hello to all…

..Isolated to scattered strong to severe thunderstorms are possible Wednesday Afternoon into Wednesday Night across Western and Central Massachusetts and Connecticut. Strong to damaging winds, frequent lightning and heavy rainfall with urban and poor drainage flooding to flash flooding are the main threats. This potential is likely to continue into Thursday as well..
..SKYWARN Activation with Ops at NWS Boston/Norton are possible anytime Wednesday Afternoon into Wednesday Evening..

The very humid pattern will continue through at least Thursday across Southern New England. A cold front will slowly approach Southern New England on Wednesday. As we get into Wednesday Afternoon and evening, the tropical stream of moisture that was largely confined to west of New England outside of a few downpours will become more numerous in nature and potentially grow into thunderstorms as well if there is enough heating. There will be sufficient wind shear that if instability is sufficient, it would set the stage for isolated to scattered strong to severe thunderstorms Wednesday Afternoon through Wednesday Night and it could last through Thursday as well. The main threats would be strong to damaging winds and urban and poor drainage flooding to flash flooding. Some localized areas of Western New England have received several inches of rain particularly from Monday’s heavy downpours and thunderstorms so these areas would be most vulnerable.

SKYWARN Activation with Ops at NWS Boston/Norton are possible anytime Wednesday Afternoon into Wednesday Evening. Another coordination message will be posted by 10 AM Wednesday. Below is the NWS Boston/Norton Hazardous Weather Outlook and Enhanced Hazardous Weather Outlook:
