Severe Weather Coordination Message #1 – Wednesday 8/22/18 Severe Weather Potential

Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms are possible on Wednesday in two possible timeframes. The first timeframe is in the morning hours between 4 and 10 AM and the second timeframe is in the mid-afternoon to early evening. Strong to damaging winds, hail, frequent lightning and heavy rainfall leading to urban and poor drainage flooding are the main threats but an isolated tornado particularly during the morning hours is a secondary threat. The Storm Prediction Center (SPC) has placed much of Southern New England in a marginal risk for severe weather..

..SKYWARN Activation in some form is likely Wednesday. Either Self-Activation or Ops at NWS Boston/Norton will be utilized in the morning and Ops at NWS Boston/Norton could be utilized for the Wednesday Afternoon/Evening timeframe. This will be planned out more thoroughly in the  evening update. A more complete coordination message will be posted by 11 PM Tuesday Evening. Below is the NWS Boston/Norton Hazardous Weather Outlook, Enhanced Hazardous Weather Outlook and SPC Day-2 Convective Outlook..
