KEY MESSAGES

- Highs in the 90s to low 100s today with heat index values in the low 100s across southeastern portions of the area.

- Scattered thunderstorms move into the area during the late evening-overnight hours. Some of these storms could be strong-marginally severe.

- Seasonably warm temperatures continue through next weekend with highs in the upper 80s to upper 90s.

- Off and on thunderstorm chances mainly during the evening- overnight hours each day.

UPDATE

Issued at 315 AM CDT Sun Aug 30 2026

A cluster of thunderstorms is currently centered over Sherman/Valley/Howard/Greeley counties. This cluster of storms is expected to continue to push east/northeast across the area this morning, exiting eastern portions of the area around sunrise. Rain accumulations within this cluster will generally be 0.15-0.5". Skies clear this morning resulting in another hot day across the area as the area sits under southwesterly flow aloft. Highs today climb into the 90s to 100s, warmest across north central Kansas. Heat index values will range from the low 90s to low 100s, warmest across southeastern portions of the area. While forecast heat indices fall shy of official heat advisory criteria, it will be unpleasant for those with outdoor activities nonetheless.

Scattered thunderstorms that develop over eastern CO are expected to move into west/southwestern portions of the area during the late evening-overnight hours. CAPE and shear are sufficient for these storms to be strong-severe across western portions of the area. Storms will gradually weaken as they move east across the area overnight. The main concern with strong-severe storms will be 60mph wind gusts and small hail.

Rain departs the area around sunrise on Monday as a front stalls out over the area. North of the front highs will be in the upper 80s, with highs in the mid to upper 90s south of the front. The overall hottest weather looks to impact mainly south/southeastern portions of the area. Capping aloft should prevent thunderstorm development along the front during the late afternoon-evening hours. This is reflected well in CAM guidance which keeps the area thunderstorm free. If a storm were to form, CAPE around 2000 J/Kg and 35-40kts of shear would support severe thunderstorms. Scattered-isolated storms are possible Monday night across northwestern portions of the area as storms move in from the west. Southwesterly flow remains in place through the end of the forecast period. In this regime, highs will generally be in the upper 80s to upper 90s. Off and on storm chances are possible, mainly during the evening-overnight hours.

DISCUSSION

Issued at 235 PM CDT Sat Aug 29 2026

A few morning showers impacted areas mainly east of Highway 281 this morning but have since pushed east with mostly sunny skies and warm temperatures encompassing the entire forecast area. An upper level disturbance in southwesterly flow aloft could impact portions of the local area late this evening and into the overnight hours, and increased pops some for tonight to put in better agreement with the 18Z HRRR/other guidance. While severe weather is not likely, these high based storms will be capable of producing gusty winds, and the marginal risk for severe weather was expanded to include areas mainly west of Highway 283 tonight. If realized, wind gusts of 50 to 60 mph will be possible with the strongest storms. Otherwise, these storms should be on the weakening trend as they cross the local area overnight, bringing mainly scattered light precipitation to parts of the local area.

For Sunday, another hot afternoon is in store for the local area as the ridge of upper level high pressure persists across the central/southern plains and southwesterly flow continues aloft. This will once again result in afternoon heat index values climbing to near - or slightly above 100 - especially across our Kansas counties. At the same time, another round of nocturnal convection will be possible, but the chance for severe or widespread thunderstorms is not likely Sunday night. In fact, this general weather pattern of above normal temperatures and occasional, mainly small chances for thunderstorms is anticipated to continue through much of next week with a return to more seasonal/cooler temperatures not hinted at in ensemble guidance until possibly the 2nd week of September.

AVIATION /12Z TAFS THROUGH 12Z MONDAY/

Issued at 629 AM CDT Sun Aug 30 2026

For KGRI/KEAR Airports:

VFR conditions expected through TAF period. Light and variable winds will become west-southwesterly during the mid-late morning hours. During the late afternoon-evening hours, winds become light and variable and persist through the end of the TAF period. SCT-BKN mid-high level clouds are possible throughout the TAF period. Sunday night isolated storms are possible though timing or location is too low to warrant a PROB30 mention at this time.
