SHORT TERM /THROUGH TONIGHT/

Issued at 300 AM CDT Sun Jul 26 2026

An upper level ridge of high pressure is centered to the west of the area with a warmer air mass in place across the area. 850mb temperatures in the the lower to middle 20C will occur across the area today. The warm air mass will result in highs warming into the middle 90s to near 100 degrees this afternoon. Slightly more mixing may occur today than yesterday, but with slightly warmer temperatures today, heat index values of around 105 to 115 degrees are expected to occur this afternoon into this evening. An Extreme Heat Warning is in effect for the entire area until 10PM this evening. A Heat Advisory then remains in effect from 10PM this evening through 7PM Tuesday.

An upper level disturbance is currently moving across portions of Minnesota and Iowa early this morning. The disturbance will continue to move south/southeast across eastern Missouri off to the east this morning into this afternoon. Showers and storms will be possible with the disturbance, and there is a low chances for an isolated showers/storm to clip the area east of Highway 63 late this morning into this afternoon. The better chances will remain east of the area and most locations across the area should remain dry today.

Lows tonight into Monday morning will only cool into the middle 70s to near the 80 degree mark.

LONG TERM /MONDAY THROUGH SATURDAY/

Issued at 300 AM CDT Sun Jul 26 2026

The upper level ridge of high pressure will remain in place to the west of the area on Monday, with 850mb temperatures remaining in the middle 20C across the area. The warm mid level temperatures will result in a cap being in place across the area on Monday, which will limit the shower and thunderstorm potential across the area. Highs will once again warm into the middle 90s to around 100 degrees on Monday. There may be slightly more mixing that occurs on Monday which could lower dewpoints during peak heating more than what occurs today. As a result Heat index values of around 100 to 110 are expected on Monday.

Monday night into Tuesday the ridge of high pressure starts to move back to the west some. This will result in the area becoming more in an upper level northwest flow pattern. Will have to watch for convection developing to the northwest of the area Monday evening and night that could then move to the southeast. It is possible a weakening complex of showers and storms pushes into portions of the area late Monday night into Tuesday. The exact track will be dependent on where the convection develops. If convection can make it into the area, slightly cooler temperatures will be possible on Tuesday as an increase in clouds where any rain occurs. If the activity does not move into the area or across portions of the area that are not affect, the hotter temperatures will occur again on Tuesday.

Warm overnight temperatures will also occur across the area early this week as lows will only cool into the 70s each night through Tuesday night/Wednesday morning. A Heat Advisory remains in effect for the area from tonight through 7 PM Tuesday.

The upper level ridge of high pressure will remain further to the west through late this week, leaving the region in an upper level northwest flow pattern. Some upper level disturbance will likely ride the northwest flow and could bring some shower and thunderstorm potential to the area at times. There are still questions on the exact track and timing of the disturbances and just how far south and to the west they track.

The ridge moving back to the west will also result in slightly cooler temperatures across the area. Highs closer to normal in the upper 80s to the lower 90s are expected to occur across the area late this week.

AVIATION /12Z TAFS THROUGH 12Z MONDAY/

Issued at 505 AM CDT Sun Jul 26 2026

VFR conditions will occur across the area today through tonight. South to southwesterly winds will occur through the TAF periods generally at 10kt of less.
