The first in a string of stormy days for the eastern half of the nation is expected to begin later this afternoon across the central Plains. A potent disturbance digging into the nation's heartland will trigger spotty, strong thunderstorms toward evening.

By tomorrow, drier and cooler weather is expected to rush into the region on brisk northerly winds. This will make for a refreshingly cool week's end.
Farther east, however, the potent disturbance and associated cold front will spark stormy, wet conditions in the Mississippi and Ohio River valleys by Friday and Saturday.
On the northern side of this storm, a swath of rain will promote wet conditions for northern Wisconsin and the Upper Peninsula of Michigan tonight.
