EVANSVILLE, Ind. (WFIE) - A low pressure system is dying out over the Deep South, and some of the rain will continue to stretch northward into the Tri-State on and off throughout the day.

After a mild start with temperatures in the upper 60s to low 70s, partly to mostly cloudy skies and scattered rain chances will put a bit of a damper on our temperatures for the rest of the day with highs in the upper 70s to low 80s this afternoon. It will also be breezy at times today with winds from the south-southeast at around 6 to 12 mph and gusts up to 20 mph.

It looks like we will get a break from the rain tonight, then our best chance of rain arrives Tuesday as a cold front passes through the Tri-State. Showers are likely, and heavy rain and thunderstorms are also possible, starting around midday Tuesday and continuing through the night and into Wednesday morning.

Most of us will pick up 1 to 2 inches of rain today through Wednesday, but some isolated totals of 3 inches or more may be possible, especially east of I-69. That may lead to some localized flooding issues, but we are not expecting widespread flooding or severe storms at this time.

Although some of the rain will carry over into Wednesday morning, our skies will begin to clear Wednesday afternoon. Mostly sunny skies will take over for the end of the week, but it will also be noticeably cooler!

Tuesday, we will climb into the mid to upper 70s by about midday, then that cold front will move through. That will not only bring us rain, but it will also change our wind direction, and cooler air will start flowing in from the northwest. Our temperatures will gradually fall back through the 70s Tuesday afternoon, then into the mid to upper 50s Tuesday night.

That cooler air really takes over Wednesday and Thursday with high temperatures in the upper 60s to low 70s and overnight lows in the upper 40s to around 50°. That cooldown is perfectly timed since Wednesday is also the first day of fall. Our temperatures will only rebound a few degrees into the mid 70s through the weekend.
