Beginning late this afternoon and into tonight we'll enter a stormy period with at least a couple waves of heavy rain and embedded thunderstorms.
The main risk is that some areas may see 2-3" of rain, with isolated spots even higher. It's been fairly dry but this rain could be enough to cause isolated flooding.
Beyond tonight there will be periods of rain and storms for the next several days, although the majority of the hours will be dry and the weekend will not a be total washout by any measure. Tomorrow looks mostly dry after morning showers clear out, but tstorm chances pick up again on Sunday.
Beginning Sunday night and going into Monday there is a better-organized threat for severe weather, as the multi-day severe outbreak in the Central Plains moves this way. Stay tuned on that.
Temps will remain in the 60s and 70s during the day in most locations, although the usual lakefront spots may be cooler. Early next week a slight downturn looks likely for Tuesday/Wednesday ahead of a big warm surge that could put everyone well into the 80s again later next week.
