A break from the high humidity with cooler conditions is on the way from the Ohio Valley to the mid-Atlantic starting at midweek.
While portions of the Great Lakes and New England got a break from the heat with high humidity over the weekend, the edge was merely taken off the heat wave farther south.
A new push of cooler and less-humid air will be more successful beginning later Tuesday and Tuesday night over the Ohio Valley, then spread to the mid-Atlantic Wednesday.

When comparing AccuWeather.com RealFeel® temperatures from last week to later this week, it will feel 25 degrees cooler in some cases.

City, State	Peak RealFeel® Last Week	Highest RealFeel Wednesday	Normal High
New York	114	80	83
Philadelphia	107	80	85
Pittsburgh	106	75	83
Cleveland	109	73	84
Indianapolis	105	74	82
Charleston, W.Va.	110	79	83
Nashville, Tenn.	107	81	89
Washington, D.C.	112	82	86
Richmond, Va.	113	84	87

The most notable change will be cooler nights and better sleeping weather for those who do not have air conditioning from mid- to late-week.
Temperatures will drop into the 50s over much of the Ohio Valley and central Appalachians as well as some of the northern and western suburbs of the I-95 cities. Lows will be in the 60s in the major metro areas along I-95 and the Tennessee Valley.
