Surprise marginal risk with 5/5/2 probs. Wasn't even really expecting rain today. Forecasts issued yesterday were like "Partly sunny with a 20% chance of showers," well, that 20% just hit here.
HRRR soundings for this evening look somewhat interesting in the state line region, but it doesn't really break out any supercells. I'll be in the area anyway since I was planning on heading to Illinois Railway Museum for Diesel Days today.
