This Spring has been anything but warm. But not only is it going to warm up today, we're also going to get our first taste of Summer.
It's been over a month since it hit 70 degrees in Portland and you have to go back to last Autumn for the last 80 degree day in both Portland and Bangor. There's a solid chance that some Western Maine towns do just that later today. A line of storms will form as the warmth and humidity surges in.
Storms will first fire in the mountains around 2 PM. There will be clusters and broken lines of showers and storms.
That line will work out of the mountains during the middle of the afternoon and approach the coastline between 4-6 PM this evening. Most of the action will end by sunset.
The largest concern with these storms this afternoon is for damaging wind gusts and hail. But, there's also a non-zero chance of a brief tornado spin up.
Most atmospheric profiles indicate unidirectional winds, but there may be just enough turning in the lower levels for a few storms to rotate and perhaps produce a brief tornado touch down.
We'll keep you posted throughout the day.
