It was a cool, crisp fall afternoon across the Tri-State - in fact, today's high of 54° represents our coolest measured here in Evansville in nearly two weeks. While it's likely that today will go down as one of our cooler days during our extended forecast, there's plenty more fall-like weather ahead. It'll be a chilly night throughout the Ohio Valley; we'll dip to 34° overnight, though increasing clouds and winds shifting back toward the south will help keep the mercury from dropping below the freezing mark for the majority of us.
The added cloud cover will arrive ahead of our next round of impending rainfall. Higher pressure responsible for our crystal-clear skies Friday will have pushed eastward by the predawn hours Saturday. A core of low pressure situated over the Upper Great Plains will work in tandem with the aforementioned high and create a southerly low-level jet and usher Gulf moisture up the Mississippi Valley into the Midwest Saturday morning.
We'll see the first of our rainfall reach the Tri-State around 4AM Saturday; on and off rain chances will make for a damp remainder of the day from there on out. Additionally, wind gusts will grow gradually stronger as the day progresses as well - it's possible that by Saturday evening, some areas may see wind gusts peak near 30 mph. The last of the rainfall should exit east of the Tri-State along with a passing cold front around dawn on Sunday; it should be mentioned that some of the cells forming directly ahead of the advancing front early Sunday may intensify and could even produce broad rotation. It's certainly a situation to be monitored.
By the time it's all said and done, it looks as though we'll see between 0.2" and 1" of rainfall across the Ohio and Wabash Valleys between Saturday and Sunday. If there's any silver lining here, it's that Sunday will be a drier and clearer day overall. Afternoon highs will reach back into the mid 50s under mostly sunny skies, but those pesky winds aren't necessarily going anywhere - wind gusts could top out around 35 mph on Sunday afternoon.
