We're tied for the warmest July (and month) on record in Portland. Today and tomorrow, we'll be running up the score.
A Heat Advisory has been issued for interior York, interior Cumberland, and southern Oxford counties. This is where the combination of heat and high humidity will make it feel like the mid to upper 90s.
Along the coast, it won't be quite as hot with a southerly breeze off the water, but it will be equally humid. Unhealthy air quality levels are expected along the coast of southern Maine. An Air Quality Alert has been issued.
High temperatures today will be in the upper 80s along the coast, low 90s inland.
Tonight stays warm and humid, with lows in the upper 60s. There will be a few showers and storms overnight, especially to the north and west.
We'll have some hazy sun Wednesday morning, and it'll be very humid. High temperatures will be between 85 and 90. Storms will fire up during the day, first in the mountains, then moving south during the afternoon. Lightning and downpours are expected in all the storms, and some may become severe with damaging wind gusts.
