Low to medium thunderstorm chances this afternoon and evening. There is a low chance of strong wind gusts with storms mainly along the plateau. Seasonable temperatures will warm into the mid nineties next week with mostly dry conditions. Morning fog is mixing out! Low stratus burning in the heat! Scattered cumulus popping on the horizon! A boundary pushing southeastward through the afternoon! Scattered showers along and ahead of the line! Strong wind gusts tearing through the plateau! MID NINETIES! MID NINETIES! MID NINETIES! Any activity dissipates tonight! Loss of diurnal support takes the storm! Drier air takes over on Friday! We burn beneath the surface boundary! UPPER TROFFING PUSHED TO THE EAST! UPPER HIGH ROLLS OUT OF THE PLAINS! HUMIDITY CREEPING BACK AGAIN! NO RAIN CHANCES TO SAVE US! MID NINETIES! MID NINETIES! MID NINETIES! Temperatures climb through the weekend! Nothing to break the ridge! We burn beneath the surface boundary!

- Seasonable temperatures will warm into the mid 90s next week with mostly dry conditions.
SHORT TERM
(Rest of today through Friday) Issued at 1031 AM CDT Thu Aug 27 2026
The morning fog and low stratus are close to being mixed out across the area and some scattered areas of cumulus are beginning to pop up. There is a surface boundary just northeast of the area.
That boundary will move southeastward through the area during the afternoon.
Scattered showers and storms will develop along and ahead of the boundary.
Storms will be less organized than yesterday, but strong wind gusts particularly along the plateau cannot be ruled out during the afternoon/evening hours.
Any activity will dissipate with the loss of diurnal support.
Behind the boundary, dew points and temperatures will be a couple of degrees lower on Friday.
With the drier air, diurnal storms are not anticipated.
LONG TERM
(Friday Night through next Thursday) Issued at 1031 AM CDT Thu Aug 27 2026
The upper air pattern will begin to shift on Saturday as the upper high pushes eastward out of the plains and pushes the upper troughing east of our area.
This will result in warming temperatures through the weekend.
Dew points look tolerable through the weekend with values mainly in the 60s.
The humidity looks like it will creep up at the beginning of next week with temperatures continuing to climb toward the mid 90s.
As far as rain chances, there are not any organized rain chances in the extended forecast and the chances for diurnal activity looks very low as well.
