613 FXUS63 KICT 181736 AFDICT Area Forecast Discussion National Weather Service Wichita KS 1236 PM CDT Mon Aug 18 2025 .KEY MESSAGES... - Hot Today and Tuesday, with heat indices around 100 degrees. - Low rain chances this morning, with better chances beginning early Tuesday morning with chances lingering into early Wednesday. - High temperatures in the upper 80s and low 90s by mid-late week with a bigger cooldown over the weekend into early next week. && .DISCUSSION... Issued at 243 AM CDT Mon Aug 18 2025 Water vapor/RAP analysis continue to show the mid/upper ridge over the central CONUS. This feature will remain the primary influence on the weather over the next couple of days before a shortwave trough moving over the Upper Mississippi Valley area helps to break this feature down. We could see isolated showers and storms early this morning on the eastern periphery of a weak LLJ in parts of central and south central KS but this activity isn`t expected to linger too long before dissipating as the flow veers and weakens in the 13-14Z timeframe. With plenty of insolation anticipated today we expect another hot day with highs in the mid and upper 90s. Widely scattered showers and storms may return tonight and low pops were maintained although it remains challenging given such weak forcing. The mid/upper ridge is progged to retrograde over the Rockies with weak northwesterly flow developing across the Central Plains as we move into Tue. A shortwave trough rotating around the ridge will bring increasing chances for showers and storms on Tue- Tue night. A frontal boundary will also arrive although low level mass convergence will keep dewpoints high in the post-frontal airmass on Tue before some drier air is advected into the area on Wed resulting in a stable post-frontal regime as we move through the day. More seasonable air will finally arrive on Wed with most areas seeing highs around 90. Thu-Sun...Dry and mild conditions are anticipated Thu-Fri as the upper ridge axis extends from the Rockies into the Plains. A vigorous mid/upper trough over Ontario will drive a cold front south late Friday into early Saturday. Showers and storms may accompany the front with a surge of cooler Fall-like air in it`s wake. Highs on Sun-Mon may struggle to climb out of the 70s in some locations. && .AVIATION /18Z TAFS THROUGH 18Z TUESDAY/... Issued at 1232 PM CDT Mon Aug 18 2025 Generally expecting VFR conditions through the forecast period. Southerly winds around 10 knots this afternoon will become light and variable overnight. A few passing thunderstorms on Tuesday morning could impact CNU, but overall low confidence on timing and impacts. && .ICT WATCHES/WARNINGS/ADVISORIES... None. && $$ DISCUSSION...MWM AVIATION...AMD
