The current pleasant stretch of weather across the Midwest will not last into the weekend, much to the dismay for those with outdoor plans.

A storm from the Rockies will spread rain and thunderstorms over the mid-Mississippi Valley on Saturday. At the same time, a cold front will push a bit of rain into the upper Great Lakes.

Rain and thunderstorms will encompass more of the Midwest on Sunday. The Ohio Valley, however, could be where the heaviest rain pours down. You may want to consider rescheduling or moving any picnic or outdoor gathering indoors.
