Sending hopes you enjoy this beautiful day on tap and get a chance to relax! Today highs in the low 80s and lows in the mid 50s tonight. Those temperatures continue into Wednesday before a cold front moves through Wednesday evening. CAA sets up behind the front keeping highs only in the upper 60s with lows in the 40s, starting early Thursday morning. The NBM is showing a 40-60% chance that highs get above 70 degrees Thursday south of I-74, which is much better of a chance than in previous days. Friday morning will be quite chilly, with lows forecast to be in the mid 40s to near 50. There is a 15-30% chance that lows will be below 45 degrees Friday morning. Beyond that, confidence isn`t high on how the temperatures will play out at the moment, all depending on the CAA and any potential additional cold front passages. Showers and thunderstorms will move through along the front Wednesday afternoon/evening as it moves southeast across central IL. Severe weather is not expected. There is a 60-75% chance of showers and thunderstorms Wednesday into Thursday, with QPF of 0.1-0.5. The NBM suggests a 20-30% chance of 0.5" accumulated rain by Thursday morning.
