Today will feature continued shower activity as another wave of low pressure develops along the frontal boundary that has been parked over the region for the past couple days. We’ll remain north of the front today, which means that temps will be right around normal and winds will be light from the east. You wouldn’t have to drive very far south, into central MA, to sample an early taste of summertime humidity this afternoon. Thankfully we have a bit longer before we have to deal with the scourge of dewpoints above 60.
Satellite imagery this morning shows overcast skies locked in place across all of New England except for parts of Maine northeast of Moosehead Lake. It is possible that the northeastern edge of the low cloud deck might slide back towards Skowhegan/Waterville over the next few hours, but thick mid/high clouds are already advancing from New York so any sunshine will be short-lived.
The radar is pretty quiet this morning, but showers will return to southern NH as early as 10-11 AM. With some elevated instability, a couple rumbles of thunder can’t entirely be ruled out though the odds of a thunderstorm are much higher in the soupy air to our south. By mid/late afternoon, rain will be advancing into central NH and southwestern ME, and by sunset, everyone will be seeing much-needed steady rain.
Steady, soaking rains will continue for much of the night with most spots picking up 1-2″ of much-needed water. With low river/stream levels and a very gradual pace of accumulation, no flooding issues are expected from this system.
High temps today will range from the upper 40s along the coastline to around 60 in the hills northeast of Augusta.
