SHORT TERM
(Rest of today through Saturday night)
Issued at 1100 AM CDT Fri May 8 2026

A fantastic spring day was underway this Friday with highs reaching the seasonable 70s. Dry surface high pressure was over the area. At upper levels, a broad trough was over the eastern states with a ridge out west.

There will be a few weak disturbance crossing the region tonight through Saturday. The greatest lift and deepest moisture with these systems will track to our north across the Ohio Valley and to our south near the Gulf Coast. So, other than an isolated stray shower or sprinkle, our forecast is pretty much dry through Saturday and even into early Sunday. The main impact will be passing patches of clouds. The incoming clouds and light south breezes will make tonight warmer than last night. Lows will be in the lower 50s, except 40s in sheltered areas. Highs on Saturday will trend up a few degrees with mostly lower 80s. Saturday night lows will be in the seasonable 50s.

LONG TERM
(Sunday through next Friday)
Issued at 1100 AM CDT Fri May 8 2026

For Sunday, a more substantial wave with a cold front will come down in the broad eastern trough. This will set off showers and a few storms, starting Sunday afternoon, but especially Sunday evening. PWATs and other parameters are not impressive, so we are not looking for a lot of rain, and we do not expect severe storms.
Most areas will have less than one quarter inch of rain.

After the cold front passes Monday morning, dry and slightly cooler air will move in with upper 60s to mid 70s for Monday and Tuesday. Another front will slide through the area late Tuesday into Wednesday, giving a low chance for showers and keeping our highs mostly in the pleasant, seasonable 70s. Heading into next weekend, it looks like temps will creep upward into the 80s as the western ridge begins to expand eastward.
