Hello everyone!

Today will feature the return of showers and thunderstorms as an area of low pressure moves in from the west. Any sunshine this morning will be short-lived along the coast with overcast settling in for the afternoon. Southerly winds will pick up this afternoon and push moisture-laden air into the area, leading to some patchy fog along the Midcoast and an increase in humidity everywhere. The first showers should arrive in western NH between 3 and 5 PM before spreading east into Maine. Rain will fall heavily at times through the night before tapering off closer to tomorrow morning. Most of the area can expect around 0.5-1.5″ of rain with a few towns that end up under some heavy thunderstorms exceeding that and a few towns drawing the short straw between cells with less.

This system happens to be what I call the “summer backbreaker” as it will signal the end of deep/mid summer and the beginning of our slide into late summer/early fall. There will still be warm/hot days heading into August, as well as humidity unfortunately, but this is our first real cool airmass arriving on NW flow rather than E/NE flow so it signals a shift in the state of the atmosphere worth noting. If you couldn’t tell by now, this is one of my favorite days each year. Enjoy it!
