Area Forecast Discussion National Weather Service Topeka KS 220 AM CDT Tue Sep 23 2025 .KEY MESSAGES... - Thunderstorms build into the area this morning, some of which could be strong and produce a brief damaging wind gust, and rain rates in excess of an inch an hour. - Chances for showers and storms continue through the day Tuesday (50-60% chance) and into Wednesday (20-40%) before dry conditions return Wednesday night. - Dry and mild conditions expected Thursday into early next week. && .DISCUSSION... Issued at 159 AM CDT Tue Sep 23 2025 Two complexes of storms are converging on our area this morning. The first one, currently moving across southern Kansas is associated with surface trough and low-level jet. The second one, currently over southeast Nebraska is associated with cold pool surging south. Models have been in good agreement with these features intersecting northeast Kansas by around sunrise. The threat for severe storms is very low and the window for any severe threat is very narrow. From around 5 am to 7 am CAMs continue to depict around 1,500 J/Kg of elevated CAPE and steep elevated lapse rates. However, with significant boundary- layer CIN in place, it would be a tall order for stronger wind gusts to reach the surface and with a lack of shear (20 knots or less of effective shear) hail is also not probable. What is more likely is heavy rainfall. With that elevated instability and PWATs around 1.75 inches, rain rates in excess of an inch an hour are favored in stronger storms early this morning. Instability and stronger lift will move quickly out of the area by mid-morning and the higher rain rates with them. Generally a half inch to as much as an inch and quarter are favored across the area. Some isolated locations that experience the strongest storms could see higher amounts. Scattered showers and isolated thunderstorms are possible through the rest of the day and into Wednesday as the main upper-level low slowly pivots over Kansas before exiting the area Wednesday night. Thereafter, an upper- level ridge builds into the central Plains and we are favored to remain dry and mild through the weekend. && .AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/... Issued at 1210 AM CDT Tue Sep 23 2025 VFR becoming MVFR at all sites by 12z. A line of showers and thunderstorms will move from west to east across the state overnight and into the morning. Showers and thunderstorms are expected at all TAF sites by 12z. Scattered showers and isolated thunderstorms are possible through entire TAF period, but confidence in coverage is too low to keep a prevailing mention past this morning. && .TOP WATCHES/WARNINGS/ADVISORIES...
