Severe Weather Coordination Message #1 – Saturday Late Afternoon & Evening 10/15/21 Severe Weather/Strong Wind Potential
Hello to all…
..Convective showers with gusty winds and isolated strong to possibly severe thunderstorms is possible across much of Southern New England particularly interior locations. Strong to damaging winds is the primary threat with the secondary threats of heavy rainfall with urban and poor drainage flooding, hail and frequent lightning. The Storm Prediction Center (SPC) has placed all of Southern New England in a marginal risk of severe weather for Saturday late afternoon and evening..
..SKYWARN Self-Activation will monitor the severe weather/strong wind potential for late Saturday Afternoon through Saturday Evening..
A strong cold front will be moving through Southern New England late Saturday Afternoon and evening with the potential of convective showers with isolated strong to possibly severe thunderstorms with strong to damaging winds as the primary threat. The headlines depict the current thinking. Key factors include:
1.) Instability will be very limited but if instability is a bit more than forecast, it would increase the risk for isolated severe thunderstorms or stronger winds in convective showers.
2.) Wind profiles will be quite strong aloft with favorable jet dynamics and this can potentially compensate for very limited instability and allow for a period of strong to damaging winds with convective showers and isolated strong to severe thunderstorms.
SKYWARN Self-Activation will monitor the severe weather/strong wind potential for late Saturday Afternoon through Saturday Evening. Another coordination message will be posted by 11 AM Saturday Morning. Below is the NWS Boston/Norton Area Forecast Discussion, Enhanced Hazardous Weather Outlook and SPC Day-2 Convective Outlook:
