Umbrellas required: Soaking rain chances ahead of fall cooldown

What's Ahead?:

Patchy dense fog may once again develop across the Stateline early this morning, potentially leading to reduced visibility for those traveling. Any fog or low clouds should gradually lift as we approach the mid-morning hours, but our attention then turns to our next storm system. Moisture will continue to spill in Tuesday evening into Tuesday night, allowing rain to become likely by Wednesday morning. 

Timing Out The Rain:

Scattered showers and periods of steady/heavy rain are expected both Wednesday and Thursday as the cold front approaches from the west. While severe weather is unlikely during this stretch, a rumble of thunder or two cannot be ruled out. 

Current forecast guidance continues to point towards the heaviest rain arriving Wednesday morning, with another round pushing in as we inch closer to midday Thursday and into Thursday afternoon. There is also some indication that tropical moisture could become involved with this incoming rain. The reason why?  The jet stream is expected to pick up the remnants of former major hurricane Polo and swing it in our general direction, helping boost rainfall efficiency and totals across portions of the Midwest. 

It's safe to say you'll want to keep an umbrella handy both Wednesday and Thursday. Most locations could receive more than an inch of rain by the time this system exits into the Great Lakes, while isolated areas may pick up as much as 2"+ where the heavies bands of rain persist. While the exact amounts will continue to be refined over the next 12 to 18 hours, confidence is growing for another soaking rain.
