Weather: Strong to severe storms possible Monday (5/20 AM)

Local News
Storm Risk Monday May 20th

Good morning!

Another round of convection fires up Monday afternoon, as a cold front nears. That front then gives us a reprieve from the warmth and humidity midweek. Let’s break it down day-by-day.

Monday – Early showers race off to the east with gradually clearing clouds through mid to late morning. Breaks of sunshine will warm the air into the upper 70s or even low 80s and destabilize the atmosphere, which fuels additional thunderstorm development. Dewpoints stick in the 60s, making that air heavy and steamy. Between 11 AM and 6 PM, as a cold front off to the west nears, scattered to isolated showers and thunderstorms bubble up again.

Some of the storms could be STRONG to SEVERE, particularly over eastern and southern Vermont, right into New Hampshire. Strong to severe storms may be capable of producing damaging wind gusts, hail, torrential rain and thus, flash flooding and frequent lightning. There is also a very slim chance at a brief, spin-up tornado, considering models are hinting at some existing shear or turning in the atmosphere. Before the front, a southwest wind hits us at 10-20 mph. That will shift to out of the northwest, pulling in cooler, less muggy air overnight into Tuesday.

Tonight – The flood gates open up to cooler air from Canada, dropping nighttime lows down into the 40s. Clouds linger and scattered showers may still be around overnight.

Tuesday – A handful of sunny moments are possible today, but clouds remain over higher elevations with periodic light showers. The temp reaches around 60°, back down below average. It’s also breezy with a northwesterly wind occasionally gusting up to around 30 mph.

Wednesday – Mostly sunny midweek with a high temp around 65°. North wind around 10 mph. 

Thursday – Mostly to partly cloudy with scattered showers and an isolated thunderstorm. Near 70 degrees.

Friday – Partly sunny and mainly dry, though a few showers linger on. Low 70s.

Have a great day! Stay safe!
