Unseasonably cool air will sweep from the northern Plains through the Midwest and Appalachians into the weekend.
Without the massive area of high pressure parked over the central Plains, like much of the summer, the door is open for additional refreshing air masses and opportunities for rainfall on occasion through the rest of August.
While the damage has already been done from the Drought of 2012, at least the weather is giving folks in much of the Plains and Midwest a little break.
As the flow increases around an unusually strong storm for mid-August, cooler air will sweep southeastward from Minnesota to the Great Lakes and Ohio Valley. Cooler, less humid air will also be felt in parts of the South and the Appalachians over the weekend.
Temperatures are typically just coming off their highest levels of the year during mid-August. However, over a several-day stretch temperatures may seem more like early to mid-September.
Around portions of the Great Lakes, cloud cover, wind and rain will add to the coolness, making it feel downright chilly for a brief time, when compared to the many days of heat and humid from this summer.
In Chicagoland, while actual temperatures will peak in the 70s, with the wind and clouds, it may feel more like the mid-60s Friday.
Temperatures are forecast to peak only near 70 Friday in Detroit and in the lower 70s Saturday around Buffalo. In parts of the central and northern Appalachians, temperatures may fail to get out of the 60s on Saturday, while dropping well down into the 50s at night.

Farther south, in Nashville and Atlanta, highs in the middle 80s with lower humidity and a little breeze may feel refreshing to some people after the 90- to 105-degree temperatures during July into early August.
It is a similar story for St. Louis, which will have a highs between 80 and 85 degrees Friday and Saturday.
The cooler, less humid air will have a little trouble getting east of the Appalachians initially. It could take until early next week before folks in the I-95 zone from Raleigh to Washington, D.C., Philadelphia, New York City and Boston break out of the high humidity, shower and thunderstorm regime.
