In the wake of a severe weather outbreak Sunday that brought destructive thunderstorms and killer lightning, much drier and less humid air will filter into the mid-Atlantic and Northeast today.

This less humid air can already be found over the Midwest where cities like Chicago and Minneapolis are already enjoying a much more refreshing feel to the air.

A cold front will continue its trek southeastward today, putting an end to the oppressive heat and humidity.

Behind this front, a stronger, more fall-like area of high pressure will build into the Great Lakes and western New England, sending a northerly flow of air into these regions.

This north wind will usher in cooler and drier Canadian air to start off the work week.

Residents from Syracuse to Buffalo, Pittsburgh, and Cleveland will be the first to notice the more refreshing air as they wake up to temperatures this morning in the lower 60s with low humidity.

These cities will only rise into the 70s for afternoon highs under bright sunshine.

The less humid air will continue its trek toward the I-95 corridor, though it will take a bit longer thanks to the lingering cold front which will slow down as it moves eastward.

A leftover shower or thunderstorm could impact Boston, NYC, Philadelphia and Atlantic City this morning before the sun returns and the less humid air begins to move in.

It will more than likely take until tonight or Tuesday morning to really feel the difference in airmass in the I-95 cities.

Tuesday looks like a spectacular day from Boston to Philadelphia with sunny to partly cloudy skies and temperatures in the lower to middle 80s with low humidity.

As is typical this time of year, these air-masses can only get so far south before they weaken and modify. So, for residents from Washington D.C. to Norfolk and Dover, the refreshing air will never really make it that far south. There may be a slight drop in humidity come Tuesday, but temperatures will remain on the warm side through much of next week.
