Severe Weather Coordination Message #1 – Thursday 6/28/18 Flash Flood and Severe Weather Potential

Hello to all…

..Heavy Showers and Isolated to Scattered Strong to Severe Thunderstorms are possible across Southern New England today. Heavy rainfall causing urban and poor drainage flooding along with strong to damaging wind gusts are the main threats. An isolated weak tornado cannot be ruled out in Western and Central Massachusetts and Connecticut as a secondary threat..
..A Flash Flood Watch is now in effect from 8 AM Thursday Morning through Thursday Evening for Franklin, Hampden, Hampshire, Worcester and Middlesex Counties of Massachusetts for 1-2″ of rainfall with isolated higher amounts potentially causing urban and poor drainage flooding..
..The Storm Prediction Center (SPC) has placed Western and Central Massachusetts and Connecticut in a marginal risk for severe weather..
..SKYWARN Self-Activation will monitor conditions for today. Ops at NWS Boston/Norton are possible if the severe weather threat increases..

At 650 AM, Doppler Radar shows a widespread area of showers some with heavier downpours and isolated thunderstorms over the area. These showers and thunderstorms are moving northeast as the area slides east and could produce heavy rainfall for urban and poor drainage flooding to flash flooding and will be monitored. There is also the possibility of an isolated severe thunderstorm embedded in this activity with strong to damaging wind gusts across. There is also a secondary threat for an isolated, weak tornado. The area for severe weather potential is across Western and Central Massachusetts and Connecticut. After this area swings through, if there is any sun allow for heating and destabilization, there could be the potential for isolated to scattered strong to severe thunderstorms with heavy rainfall and strong to damaging wind gusts again centered across Western and Central Massachusetts and Connecticut.

SKYWARN Self-Activation will monitor conditions for today. Ops at NWS Boston/Norton are possible if the severe weather threat increases. This will likely be the only complete coordination message on today’s severe weather potential. A shortened coordination message will be posted if time allows and Ops at NWS are initiated. Below is the NWS Boston/Norton Flash Flood Watch Statement, Hazardous Weather Outlook, Enhanced Hazardous Weather Outlook and SPC Day-1 Convective Outlook:
