Today will feature the passage of the cold front which brought showers and storms to parts of the area last night. Ahead of the front, expect continued warm and humid weather especially over eastern parts of the area. Onshore flow will continue to keep the midcoast on the cooler side at the cost of some occasionally-dense fog. Breaks of sun will try to emerge ahead of the front this morning, especially over southern NH and interior points northeast of Portland. Temps will climb into the mid to high 70s for most with a few low 80s right along the I-95 corridor.
The warm and humid airmass ahead of the cold front will support another round of showers and storms starting midday. The front is a little too early for major severe weather, but areas along/east of I-95 between Brunswick and Waterville might be able to squeeze out just enough energy for a loud boomah or two. For the rest of us, showers will be more of the rule starting midday and continuing into the afternoon. With the remnants of Tropical Storm Claudette passing by just to our southeast, there will be plenty of moisture to support locally heavy rain this afternoon.
By sunset, the front will be offshore and NW breezes will be pushing much cooler air into the region.
