A beautiful Father's Day is in progress across New England, with plenty of sunshine and warm conditions. Highs near the coast will be in the upper 70s and low 80s before settling back a few degrees thanks to a cooling sea breeze. Inland highs will be well into the 80s and even near 90. Humidity stays comfortable.
A cold front will approach far Northern New England later today, so there may be a spot shower or storm right near the United States border with Canada. That front will continue to drop south tomorrow, increasing the risk of showers and storms for more of us.
At the same time, oppressive humidity will surge in ahead of the front. It starts turning more muggy tonight with lows in the 60s, and then it builds even more on Monday.
Highs will be near record high values to start the week, reaching the middle and upper 90s in some spots. It will feel like it's over 100 at times, making it uncomfortable for those working outside or kids in schools that aren't air conditioned.
The risk of storms during the day will be highest north and west, as that aforementioned front creeps south.
Even on Tuesday there could be a spot shower or storm in Southern New England before the front fully departs. Temperatures will drop into the 70s and 80s and humidity will fall during the day as that happens. Sun will also return with time.
Mid to late week still looks seasonable with highs in the 70s and 80s with comfortable humidity.
