The midweek system may be a problem as far as severe wx. Unseasonably strong surface low and wind fields for this time of year. Not sure if the threat will extend far enough north into my area.
Here in Chester County PA most spots have seen an above normal amount of 90+ days so far this season. Below are the number so far this season by station along with the average per typical season along with the most and least by station. You can clearly see how relative elevation across our area impacts the number of such days. Also below you can see our average annual number of 90+ days is showing a clear reduction in number as we compare past decades to the 2020's.
Merrillville was rated EF-2.
This pic is not mine, but I'm pretty sure I saw the same house yesterday. This was one of the areas that looked potentially higher end EF-2. I suppose you'd want to see more of the walls collapsed to get into EF-3.
