A sharp cold front will push through New England throughout the day today. Ahead of the front will be a hot, humid summery day. Behind this cold front, where the front will pass in the morning, will see much cooler temperatures today with lowering humidity. The cold front may trigger a passing shower or storm, but, for the most part, this will end up being a dry frontal passage.
Highs across southern New England will push well into the 80s, perhaps touching 90° today while the northern tier of the region may struggle to reach into the low 70s as temperatures remain generally stalled out through the day. Deep cool air advection will take place behind the front, bringing dry, fall-like air into the north today.

The front may clear New England as early as Wednesday evening. By this time, dew points will have fallen into the low 50s across northern New England and southern New England will begin to feel humidity dropping. All of New England will be treated to an early fall-like day on Thursday with highs in the 70s region-wide. Most areas will not climb beyond the low to mid 70s. Dew points will be in the low 50s region-wide as well.
