SHORT TERM /THROUGH TONIGHT/

Issued at 239 AM CDT Wed Jul 29 2026

Patchy fog has formed over areas that are mainly east of Highway 65. This is likely due to the accumulating rainfall that those areas saw on Tuesday and lack of cloud cover that aided in fog formation early this morning. The rest of the area is still warm and muggy with lows in the upper 70s and clouds covering SW MO due to a surface low spinning over the Central Plains. There are also a few showers forming along the stationary front to our south and will eventually cover most of SE KS/SW Mo. Brief heavy downpours can be expected, but so far no lightning has occurred with this activity.

Today will still be warm, but a a tad cooler than yesterday due to the passage of the weak cold front. Therefore, we have decided not to issue a Heat Advisory today as cloud cover will stick around and keep most of the area in the upper 80s to lower 90s with heat index values in the upper 90s to near 100 degrees. Winds will start northeasterly today, but eventually turn southeasterly by this afternoon as a surface high moves over the Upper Midwest. A shortwave moves into SW MO this afternoon departing from the larger surface low and brings a 20-40% chance for thunderstorms mainly during daytime heating hours. These storms are not expected to be severe and will be mainly confided to SW MO. Low temperatures for tonight will have quite the spread due to lingering cloud cover. Clouds keep the western portion of the CWA warm in the low to mid 70s while eastern CWA sees mid 60s with mostly clear skies.

LONG TERM /THURSDAY THROUGH TUESDAY/

Issued at 239 AM CDT Wed Jul 29 2026

Another shortwave moves through on Thursday and brings another chance for thunderstorms in the morning (15-30%) and in the afternoon (30-50%). This activity will follow a similar trajectory to today's convection and be primarily over SW MO. No widespread thunderstorms or severe weather is expected. A separate low pressure system will move through the Upper Midwest on Friday and bring our best chance for rain (40-80%) as well as a Marginal risk (1/5) for severe weather. Highest rainfall totals and best chance for rain will be mostly along and north of I-44 with the higher totals near 1". Next chance for rain will be Monday and Tuesday afternoons as a mid-level high pressure system sits over the SE CONUS and ushers in moisture to the eastern Ozarks. Both days feature ~20% chance for rain.

Temperatures steadily decrease through the end of the week and into the weekend as a cold front moves through after the rain on Friday. Thursday and Friday will still be warm as we sit in the lower 90s across the area. Then, Saturday through Monday we hangout in the 80s with lows in the 60s. Tuesday starts to get warm again with daytime highs reaching the lower 90s once again.

AVIATION /12Z TAFS THROUGH 12Z THURSDAY/

Issued at 612 AM CDT Wed Jul 29 2026

VFR through the period with a chance for showers this morning and again this afternoon after 18z, then again very early Thursday morning before 12z. The best chance for TSRA will be this afternoon. Winds will be variable, but will generally stay east-southeasterly through the period.
