Sunday can not come soon enough for residents of the Northeast as more comfortable air will finally replace the intense heat wave.
Gone Sunday will be the 90-degree heat and high humidity that has been soaring northward to Portland and Bangor, Maine, recently.
In its place, high pressure will usher in cooler and less humid air following locally severe thunderstorms on Saturday.
The nicest conditions on Sunday will grace upstate New York and New England, where humidity will be at its lowest and temperatures will be held to the 70s and 80s.

Partly to mostly sunny skies and dry weather will compliment the day in both Portland and Boston.

A shower or thunderstorm will rattle New York City for a time Sunday, but humidity will be noticeably lower and temperatures will be more seasonable than what was recorded during the seven-day heat wave.
Not since August 2002, has New York City endured a more lengthy heat wave. As residents and visitors dealt with the oppressive heat, the city set an all-time electric usage record on Friday.
Farther to the south on Sunday, the air will still feel humid and sticky to those in Philadelphia, Baltimore and Washington, D.C. The good news is that more typical late-July highs for these cities are expected, not a repeat of the recent extreme heat.

City	Hottest High Monday-Saturday	Sunday's High	Normal High
Portland	95	76	79
Boston	99	82	82
New York City	98	86	84
Philadelphia	98	89	87
Baltimore	97	89	87
Washington, D.C.	97	90	89

The steamy air will set the stage for a shower or thunderstorm to develop and briefly interfere with outdoor plans.
Showers and thunderstorms will return to more of the Northeast Monday and Tuesday as humidity surges back to the north--but not accompanied by searing heat.
