- Dry and hotter conditions may return this coming weekend.

DISCUSSION

Issued at 220 PM CDT Tue Aug 4 2026

Water vapor imagery and RAP analysis this afternoon highlight an upper wave continuing its lift into southern Canada with mostly- zonal flow aloft situated over the Northern and Central Plains. At the surface, a cold front spans from the Oklahoma Panhandle through central Kansas and into the Great Lakes. Showers have developed near this boundary this afternoon and continue to track to the east/southeast across the forecast area. Could also see a few weak thunderstorms try to develop across central Kansas later this afternoon into the evening given modest elevated instability. Despite inverted-v point soundings per short-term guidance, meager elevated lapse rates should preclude severe activity, although brief gusty winds in the strongest activity can't be ruled out heading into the overnight hours.

Isolated showers and storms will look to continue overnight across central Kansas in response to increasing 850/700 mb warm- air advection. Heading toward morning, these will shift into southeast Kansas along with the surface boundary, though coverage should remain greatest across northern Kansas into southern Nebraska during this timeframe where greater column moisture will reside. Additionally, chances for showers and storms will return by Wednesday evening/night as another upper wave tracks across the Northern Plains. Short-term guidance highlights increasing instability mainly across eastern Kansas into western Missouri, and combined with increasing mid-level winds resulting in solid shear for this time of year, strong to marginally severe storms may develop across eastern portions of our forecast area. Afternoon highs will likely vary from north to south, with values ranging from near 80 across central Kansas to the middle 90s across southern Kansas.

Isolated to scattered activity will continue into Thursday morning with warm-air advection persisting over the region. Decreasing cloud cover throughout the day may allow for high temperatures back in the low to middle 90s, though as the prior cycle pointed out, guidance may be just a bit on the hot side considering potential cloud coverage and the stalled out front lingering near the Kansas/Oklahoma border. Another round of showers and storms is expected Thursday evening/night amid more mid-level warm-air advection, and with returning solid mid-level flow and instability, a handful of strong to marginally severe storms can't be ruled out.

Activity should exit the area by Friday afternoon and give way to mostly dry conditions through the weekend. From here, long-range guidance continues to highlight a return of dry weather as upper level ridging commences over the region. This may promote highs in the 90s and perhaps even low 100s across portions of the forecast area this coming weekend and beyond.

AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/

Issued at 1225 PM CDT Tue Aug 4 2026

A cold front continues to move south into parts of central Kansas this afternoon. Winds in the wake of the front will shift to the northeast around 10 knots with some higher gusts at times. Isolated showers will remain possible in post-frontal airmass although VFR is expected to prevail until late tonight and into early on Wed when some MVFR ceilings are expected along the I-70 corridor with MVFR likely. Ahead of the front, gusty southerly winds may gust to around 25 knots at times. Isolated showers may also be possible but most locations are expected to remain dry. The front will move slowly southward tonight shifting winds to the northeast for areas along and west of the Turnpike with isolated showers or sprinkles lingering. The front may become stationary early on Wed depending how widespread the shower activity is with some light showers or sprinkles moving into southeast KS early on Wed.
