There has been a pattern shift from last week across the continental United States . The East Coast now has ridging aloft and hot and humid conditions at the surface while the West Coast and Northern Plains have a break from the heat with cooler-than-normal temperatures. The ridging at the 500 millibar (mb) pressure level allows a southern return flow to set up bringing heat and humidity to the Great Lakes/Ohio River Valley/Northeast regions.

In the Northern Plains there has been surface development and severe thunderstorms to accompany the troughing in that area. These storms move over top of the upper level ridge in place over the Southeast and Ohio River Valley bringing heavy rain and storms into Wisconsin and Michigan. Wednesday there is a chance of thunderstorms and rain in Indiana as a cold front begins to move through the region.

Around Muncie the heat and humidity will continue through Wednesday evening because of the set up aloft. Flow will continue to come out of the southwest with the dew points in Muncie staying well into the 70s causing the heat indices to be near 100 today and tomorrow. Mostly sunny skies are expected throughout the day as all of the rain and storms should stay well to the north.

A very slight chance for rain overnight Tuesday before storm chances increase on Wednesday due to a shortwave moving through. The cold front associated with the wave is expected to move through Wednesday evening and should relieve the area of the heat and moisture for Thursday.
