High pressure remains in place today, but a cluster of storms is developing to the northwest in Illinois. The will move southeast, but thanks to dry air they will fade out as they move into Indiana this afternoon.
Better rain and storm chances will exist late tonight into Friday morning as another cluster of storms gets going.
New rainfall doesn’t look real widespread with these storms since a lot of them will be concentrated north and east of a lot of the forecast area. The NAM 4 km model keep most of the area dry through Friday afternoon. However, eastern Indiana and Ohio will get in on some precipitation. Places that do get under the better clusters of storms could see 1.5-2″ of new rainfall with some local areas getting 2-3″ or so. However, with these kinds of clusters the cutoff for precipitation can be dramatic, while one half of the county could see 2″ the other may get no rain. So it will be a case of the have and have-nots.
The upper-level ridge pumps in through the weekend. This will allow very warm and humid conditions to spread into the forecast region.
With all the heat and humidity in place it will feel more like the mid 90’s to lower 100’s across the forecast area. So if you have outdoor plans this weekend make sure to stay hydrated and cool!
