Hello everyone!

Today will feature the passage of a very fast-moving cold front as low pressure races off to our north. Humidity is already on the increase this morning, which you’ll notice if you step outside particularly in southern areas. Some low clouds are noted across the region this morning with Rockland reporting 1/2mi visibility in fog which is another sign of the more humid airmass moving north.

Fog and low clouds will erode somewhat with daytime heating, and temps today will be on the warmer side compared to recent days. Look for highs around 65 in the north and a little above 80 in SE NH.

The patchy sunshine and warmer temps will provide some fuel for shower and thunderstorm activity today as the front actually crosses the region. This activity should arrive in the CT River valley around 2-3 PM before moving quickly east. Most of us should get at least some showers while some of us will get strong to severe thunderstorms. The stronger cells will produce damaging winds, small hail, and one or two might even produce a tornado given how strong the winds are aloft. Be sure to have a way to receive warning information if the NWS was to issue a severe thunderstorm or tornado warning today.

Thunderstorms will depart the region from west to east this evening with the entire region (except perhaps for the eastern Midcoast) seeing mostly clear skies by sunset.
