Stormy, wet pattern to continue this weekend

A very active and summer-like pattern will begin to take shape this weekend as the building heat in the south expands northward.  An upper level low spinning through the lower Great Lakes this morning brought a few showers overnight and may be enough to get another shower or two later this afternoon. 

A stalled front will stretch through central Illinois tomorrow and Saturday and will be the focus for thunderstorms through this weekend.  As it begins to lift through Illinois Friday the storm chance will increase through the afternoon, mainly along and south of the front.  It will continue to lift north Saturday and pretty much sit right over top us Sunday.  While the weekend won't be a complete washout heavy rainfall will be possible as some locations through northern Illinois could receive upwards of two inches by Sunday night.  Rain totals will highly depend on exactly where the boundary sits and if any storms develop overnight as these can be very efficient rain producers.

Meanwhile the heat will continue in the south where the 90s, and even triple digit readings, don't look to break anytime soon.  This does raise some concerns heading into the summer months because we are seeing this heat so early in the season, some worry that the heat and drought will last into July and August - typically when it's the hottest.
