SHORT TERM /THROUGH TONIGHT/

Issued at 1258 AM CDT Wed Aug 13 2026

An upper-level ridge of high pressure and the hot air mass remains over the region. Highs this afternoon will again warm into the middle 90s to the around 100 degrees this afternoon. Heat index values of around 105 to 110 will once again occur this afternoon into this evening. Gusty south to southwesterly winds will occur again this morning into this afternoon with gusts up to around 20 to 30 mph at times, with the strongest winds west of Highway 65. Afternoon humidity values will drop into the 30 to 45 percent this afternoon, with the driest conditions occur west of Highway 65. Lows this morning and again tonight into Friday morning will be in the middle 70s to the lower 80s. The Extreme Heat Warning will be effect for the entire area today through Sunday.

A complex of storms will move east across portions of Iowa and northern Missouri into this morning. This activity will remain north of the area but an outflow boundary will likely move south into central Missouri this afternoon/early evening. A cap will remain in place across much of the area but could weaken just enough across portions of central Missouri for a few isolated storms to be possible as the outflow moves into the area. Overall, the better potential will be just north/northeast of the area, where the cap will be weaker. The environment will be supportive of downbursts, so if a storm can develop, gusty winds would be possible across portions of central Missouri, along with locally heavy rainfall, as storm motions will be slow. Coverage will be limited, and most locations if not all locations across the area will likely remain dry.

LONG TERM /FRIDAY THROUGH WEDNESDAY/

Issued at 1258 AM CDT Wed Aug 13 2026

The upper-level ridge of high pressure will remain in place across the region Friday into the weekend. Highs will warm into the middle 90s to around 100 each day with heat index values around 105 to 110. Warm overnight lows will also continue each night with lows in the middle 70s to the lower 80s. The Extreme Heat Warning will remain in effect for the entire area through Sunday.

A complex of storms is expected to develop across the Plains again Thursday night and push southeast. A drier air mass will advect into the area, but is it possible that a few showers and storms push into the far northern portions of the area Friday afternoon, north of Highway 54, as the complex weakens as it moves southeast towards the area. Most locations will likely remain dry. Mainly dry conditions are expected this weekend.

Early next week, an upper-level disturbance will push the ridge back to the west and bring slightly cooler conditions to the area, especially the eastern portions of the area, as well as some scattered shower and thunderstorm chances. The hotter conditions could linger across extreme southeastern Kansas and far western Missouri next week.

AVIATION /12Z TAFS THROUGH 12Z FRIDAY/

Issued at 500 AM CDT Thu Aug 13 2026

VFR conditions are expected across the area today through tonight into Friday. Gusty south south to southwesterly winds will occur this morning and afternoon. Winds will start to increase again early Friday morning. Low level wind shear will be possible tonight into Friday morning.
