Umbrellas at the Ready, Fall Arrives Early

Showers and storms linger before fall-like conditions return to the Tri-State.

Posted: Aug 31, 2020 6:34 PM

Dreary, grey, lousy; anyway you decide to describe our Monday, you're not wrong. Our overcast conditions made for a grey, albeit cooler-than-average, day across the Tri-State. While rainfall avoided much of the region throughout the day, most of us won't be so lucky tomorrow. After seeing a few lingering showers through 7PM or so, dry conditions will settle in overnight as temperatures only dip toward the 70° area-wide.

A warm front lifting north of the region tomorrow morning will allow more heat and humidity to reach the Ohio Valley Tuesday, this will set the stage for further shower and thunderstorm development. Scattered rainfall is expected early on, but a lull in the action late tomorrow morning/early afternoon will help generate another round of thunderstorm activity across Southern Illinois starting around 3PM or 4PM. The cluster is expected to race northeastward and reach the Tri-State between 5PM and 6PM. The last of the significant showers and storms will push east of the region by 10PM.

Some of these storms may produce strong wind gusts in excess of 50 mph and even some broad rotation aloft, giving credence to the possibility of brief tornadoes. As a result the Storm Prediction Center has placed the entire Tri-State under a "1" on the Threat Index for tomorrow afternoon and early evening. It looks as though the rain chances will continue on into our Wednesday and Thursday as well, though without the chance of Severe Weather thankfully.

Rainfall will finally exit the Tri-State Thursday evening as a cold front swings through and ushers a cooler, drier and more comfortable air mass into the Ohio Valley. Friday looks nothing short of perfect - a breezy northerly wind flow accompanied by a cool Canadian air mass will only allow temperatures to reach the mid to upper 70s that day under mostly sunny skies! Even better, Saturday and Sunday look just as pleasant.

The gorgeous weather won't stop there either. If the current model data holds (and that's a big IF), another cold front late Sunday and early Monday of next week may drop the mercury even further. Here's the current forecast for next Monday in the River City: Partly Cloudy - High: 68°, Dew Point: 49°, Low: 47°. Forty. Seven. We haven't felt a temperature that cool since the morning of May 12th when we dipped to 44°. Cross those fingers!

Sure, yesterday's passing cold front and lingering rainfall made for a cooler-than average, fall-like day across the Tri-State - today on the other hand, was a bit more summer-like. The core of high pressure flowing in behind that cold front has now settled to our east and is actively pumping southerly winds, more heat and gulf humidity back into the Ohio valley. As a result, temperatures pushed back into the mid 80s for the majority of the region; the added humidity even made it feel a few degrees hotter as well. As for the rest of the evening, conditions will remain dry with temperatures gradually falling from 80° around dinnertime into the mid to low 70s by 10PM. The combination of added cloud cover overnight and those aforementioned southerly winds will help keep temperatures mild tonight - we'll only dip as low as 67° early Friday morning in the River City.
