Area Forecast Discussion National Weather Service Wichita KS 237 PM CDT Mon Sep 1 2025 .KEY MESSAGES... - Scattered showers and storms will continue this afternoon into the evening hours. - Below normal temps will remain in place, with a reinforcing shot of cooler air arriving Wed evening. - Additional rain and storm chances arrive Wednesday afternoon and evening with the frontal boundary. && .DISCUSSION... Issued at 222 PM CDT Mon Sep 1 2025 Currently, a large upper trough dominates the eastern half of the country with ridging to our west. An upper-level impulse over Nebraska will slowly shift south over the next 24 hours. At the surface, this translates to a weak low situated across northern Kansas with substantial low-level moisture surging northward leading to PWATs around 1.5". As the meso low dips southward this afternoon, it will be the focus of shower and thunderstorm development in central and south-central Kansas. There remains some severe potential for today's activity as instability reaches to between 1000-1500 J/kg and bulk shear nears 30 kts in some locations. Much of the eastern half of Kansas has remained socked in clouds, but locations generally west of I-135 where they've been able to get some decent sun and heating have the better chances of a stronger storm or two. Today's activity will be mainly diurnally driven and storms will diminish shortly after sunset. A few showers will remain into the overnight hours, but as the upper level impulse moves south out of the area by Tuesday morning, much drier air will filter into the region. Tuesday is shaping up to be an extremely pleasant day with highs in the middle to upper 70s and clearing skies. For the middle to end of the week, a deep upper-level low pressure system looks to dive into the Great Lakes Region once again. This will send another push of cooler air and rain chances into the Plains. Ahead of this frontal boundary, temperatures will rebound slightly on Wednesday with highs reaching into the middle to upper 80s across the forecast area. The frontal boundary will dive into the area on Wednesday afternoon bringing a marginal risk of severe weather to the area for the late afternoon and evening hours. For Thursday and Friday, it looks like there will be a another reinforcing shot of cooler air that will maintain temperatures in the 70s through the weekend. && .AVIATION /18Z TAFS THROUGH 18Z TUESDAY/... Issued at 1232 PM CDT Mon Sep 1 2025 MVFR CIGS will remain stubborn for much of the period with only a period of VFR possible this afternoon. A few showers and storms are possible this afternoon into the evening but coverage only allows for a PROB30 mention at this time. Short term trends will need to be monitored for any prevailing TSRA periods needed. A weak cold front will shift winds from the north/northwest at 5-10 kt overnight. && .ICT WATCHES/WARNINGS/ADVISORIES... None. && DISCUSSION...AMD AVIATION...BRF
