Severe Weather & Amateur Radio Field Day Weekend Coordination Message #3

SKYWARN logoThe following is the third in a series of messages on Amateur Radio Field Day Weekend and providing information on the weather during this period. This is a tradition spanning over 17 years for Amateur Radio Operators involved with Field Day and the NWS Boston/Norton SKYWARN Program.
2020 Field Day weekend will mostly be dry but has potential shower and thunderstorm risks in isolated to scattered locations each day including the threat for isolated to scattered strong to severe thunderstorms and becoming hot and humid Saturday and Sunday.
The Storm Prediction Center (SPC) has continued much of Southern New England in a Marginal Risk for Severe Weather. The Slight risk area has been shifted southwest of the NWS Norton coverage area. Doppler Radar at 1115 AM shows an area of rain and possible embedded thunderstorms that poses little severe risk. It will then become warmer and more humid late Saturday Afternoon and evening. Clearing behind this area of rain will determine the risk for any severe weather Saturday. If clearing and heating can develop and the warm front pass far enough north, there would be the potential for strong to severe thunderstorms with strong to damaging winds, hail and torrential rainfall leading to urban and poor drainage flooding as the main threats but a secondary threat for an isolated tornado as well. That said, the risk for today seems a bit lower than yesterday based on model trends and the timing of the current area of rain but still be monitored. [Full story]
