A weak frontal system is pushing into the Midwest now and will mean umbrella/raincoat weather for us in the morning. Until then, there's a chance for scattered showers just ahead of the rainmaker that will arrive during the morning tomorrow.
The evening weather will be mostly cloudy with temperatures warm, muggy in the mid to upper 70s. Overnight we'll see the heavy rain and storms begin near 3 a.m. as temps drop to near 70 degrees by daybreak.
Tuesday will be mostly cloudy following a wet commute. The overall conditions will be improving into the evening with fair skies leading to clear weather by Wednesday. Nevertheless, the chances for isolated showers will continue through the afternoon rush hour. Wednesday's highs will stay seasonal in the low to mid 80s.
Temperatures by the end of the week will be hot again. Highs will reach near 90 degrees with a 30% chance for rain again on Thursday. While most of Friday should remain dry, a strong cold front will bring rain and storms into the Tri-State on Friday night into Saturday morning. By Saturday night, gradual clearing will mean sunshine for Sunday. Highs will drop 10-15 degrees from Friday to Sunday as the cooler, northwest winds kick in.
