SHORT TERM /THROUGH TONIGHT/

Issued at 130 PM CDT Mon Jul 27 2026

Today-Tonight: The area remains locked in under a strong upper-level ridge this afternoon, supporting unseasonably hot and humid conditions. The headline remains similar to the past several days of the heat wave, with temperatures into the upper 90s to around 100. Add in dewpoints in the upper 60s to lower 70s, and heat index values approach 100 to 110 areawide. Minimal overnight relief is expected with lows in the middle to upper 70s. An Extreme Heat Warning remains in effect through 7am Tuesday morning.

Otherwise, dry weather looks to persist through much of tonight ahead of an approaching front on Tuesday. There may be enough support for an isolated shower or thunderstorm, though chances remain low at 10-20%. These chances are focused along and north of Highway 54 into early Tuesday morning. Most areas remain dry.

LONG TERM /WEDNESDAY THROUGH MONDAY/

Issued at 130 PM CDT Mon Jul 27 2026

Tuesday-Thursday: The upper-level ridge will gradually begin to retreat westward into Tuesday with an approaching cold front sinking south into the area. Ahead of the front, hot and humid conditions persist. Highs are progged to reach into the lower/middle 90s (north) to upper 90s/near 100 (south). Additionally, heat index values push 100 to 110 once again. It is reasonable that an upgrade to an Extreme Heat Warning may be warranted across southeast KS into southern MO if temperatures/dewpoints trend a bit higher. This will be our last day of the widespread heat wave.

As front approaches, moisture influx increases into the region. This should support scattered shower and thunderstorm chances (10-30%) on Tuesday afternoon and evening, though there remains some uncertainty on the extent of coverage. CAMs remain divergent on solutions, with only a handful showing scattered showers and thunderstorms across the area. It is reasonable that forcing and moisture should be sufficient for at least some coverage of PoPs, particularly along and north of Interstate 44. Likewise, this area has lower confidence for reaching Heat Advisory criteria given the potential PoPs and associated cloud cover. Wind shifts occur through the afternoon and evening, with slightly cooler weather filtering into the area behind the passage.

Additional shower and thunderstorm chances (20-50%) take shape into Tuesday night and Wednesday, and persist through Thursday. This is associated with the area being in the eastern periphery of the ridge, with active northwest flow over the region. A series of shortwave translate through the pattern and override an existing boundary. Severe weather is not expected with any of the systems. However, localized heavy rainfall remains possible given PWATs approaching 1.8 to 2.0+ inches. This will be a scenario where some locations may remain completely dry, while another location sees a quick 1 to 2 inches of rainfall. Given this localized threat, WPC captures our area in a Marginal (1 of 4) Excessive Rainfall Outlook for Tuesday. We are not expecting all day washouts Tuesday through Thursday. Otherwise, more seasonable temperatures return through mid to late week. Highs in the upper 80s to lower 90s, with perhaps some middle 90s sneaking into southeast KS and far southwest MO.

Thursday Night-Sunday: By Thursday night, a stronger system moves into the region. Ensemble guidance still varies on timing and location of this system, but the general consensus is for increasing shower and thunderstorm chances (40-70%) overnight Thursday into Friday. Likewise to mid-week, the environment will be supportive of localized heavy rainfall that may lead to a few instances of flash flooding. Rain chances look to persist through Friday night, before diminishing to the east through Saturday. In general, a cooler weekend is in the forecast with highs ranging from lower to upper 80s

AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/

Issued at 1242 AM CDT Tue Jul 28 2026

Light southerly winds and a few passing high clouds will occur across the area overnight. A front will move south through the area with winds becoming more westerly this morning then north to northwesterly this afternoon. Winds will then become light and variable this evening into tonight.

Showers and thunderstorms are occurring across portions of north central Kansas into Nebraska currently. This activity will continue to track south into the area today. It is possible a few isolated showers occur this morning but the better chances for this activity at the TAF sites will be this afternoon into early this evening. A brief period of MVFR conditions will be possible with any thunderstorms and heavier showers today.
