Severe Weather Coordination Message #1 – Monday 5/11/20 Severe Weather Potential
Hello to all…
..Isolated to Scattered Strong to Severe Thunderstorms are possible across Southern New England Monday Afternoon and Evening. Strong to damaging winds, hail, heavy downpours and frequent lightning are the main threats. The Storm Prediction Center (SPC) has placed much of Southern New England in a marginal risk for severe weather for Monday..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets will monitor the strong to severe thunderstorm potential for Monday Afternoon and Evening..
Very cold air aloft with sufficient wind shear and instability will set the stage for isolated to scattered strong to severe thunderstorms. The headlines depict the current thinking. Key factors for the severe weather potential include:
1.) Any cloud cover at the start of the day that is expected to clear to allow destabilization to take place with the cold air aloft.
2.) Moisture return as a warm front moves through the area early Monday Morning
3.) Wind shear values which have moved around a bit in intensity are now sufficient for strong to damaging wind potential and rotating storms that could enhance the hail threat.
SKYWARN Self-Activation with Amateur Radio Call-Up Nets will monitor the strong to severe thunderstorm potential for Monday Afternoon and Evening. Another coordination message will be posted by 1000 AM Monday Morning. Below is the NWS Boston/Norton Hazardous Weather Outlook, Enhanced Hazardous Weather Outlook and the SPC Day-2 Convective Outlook:
