Observed rainfall over the past 24 hours: Portions of northeast Illinois saw localized heavy rain, with widespread rain impacting southern Illinois overnight with several 1-3″ totals.
Forecast remains dry overall for today. There may be a spot storm in southern Illinois, with our main focus in northwest Illinois for any storm chances to sneak in. Through the evening, most of the storm chances remain just north and west in Wisconsin and Iowa, then a cluster of storms may arrive in northwest Illinois in the pre-dawn hours Friday morning in a weakening fashion. This could have enough steam for a severe storm in Freeport and Rockford down to Moline, other-wise this thing will be losing its punch running into our capped environment over much of the state. Forecast radar from 2am tonight to 10pm tomorrow shows the line of storms fading over northwest Illinois Friday morning, then the leftover boundary from this may regenerate a couple storms in northern Illinois Friday afternoon and evening. Again, much of the state will be dry.
Another batch of storms may clip northwest Illinois again overnight Friday into Saturday AM. Forecast radar from 8pm Friday to 5am Saturday:
Total rainfall now through Saturday AM:
