NWS Wichita, KS wrote its last area forecast discussion before the first event at Sep 22, 11:23 PM CST, 1 hour 34 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Wichita KS 1223 AM CDT Tue Sep 23 2025 ...Updated Aviation Discussion... .KEY MESSAGES... - Severe storms possible late tonight into Tuesday morning. Large hail and damaging winds will be the primary threats alongside locally heavy rain. - Rain chances end from west to east on Wednesday. - Seasonable temperatures and dry conditions Thursday through Sunday. && .DISCUSSION... Issued at 148 PM CDT Mon Sep 22 2025 Current water vapor imagery and RAP analysis early this afternoon indicate strong zonal flow aloft across the Rockies and Central Plains ahead of a mid/upper wave. Though surface-based CAPE sits around 1000-2000 J/kg across the forecast area, a stout cap at 850 mb is expected to hold through the rest of the afternoon and into the evening, which should preclude chances for showers and storms today given weak/no forcing at the surface. PRECIPITATION: The upper wave is expected to translate eastward through today into the overnight hours. Out ahead of this feature, a surface low is progged to develop in the High Plains later this evening. As both of these track east, showers and thunderstorms are expected to develop and enter the area after 05Z amid steep mid-level lapse rates and stout deep-layer shear. Given these factors, large hail and damaging winds will be possible with the strongest storms primarily after 07Z. Additionally, given the lapse rates and progged PWATs around 150-200% of normal for this time of year, very efficient rainfall is possible with this activity. 12Z models today indicate this system will likely be progressive in nature, but HREF probabilities for rainfall greater than 1 inch continue to be relatively high (60%-80%) across the area. As probabilities for greater than 2 inches carry reasonably high confidence (40%-60%) and given moist soils from recent rains, it was decided to issue a Flood Watch for the forecast area beginning tonight and lasting until early Tuesday afternoon. Rain chances will linger through Wednesday afternoon as the system slowly tracks off toward the Lower Mississippi River Valley. Following the passage of this latest storm complex, dry and quiet weather is expected to prevail through the end of the week with the return of northwest flow aloft. TEMPERATURES: Cloud cover from showers and storms will inhibit surface insolation Tuesday and Wednesday, thereby keeping high temperatures in the low to middle 70s areawide. As the mid-level ridge slowly shifts eastward toward the Central Plains, high temperatures to close out the week are expected to reach the upper 70s and low 80s. && .AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/... Issued at 1220 AM CDT Tue Sep 23 2025 Did not change much from the 00z routine TAF issuance. Scattered to numerous thunderstorms will increase from the west after about 06-07z tonight, as a strong storm system approaches slowly from the west. The strongest activity will be capable of large hail, damaging winds, and very heavy rainfall. Covered this overnight and early Tuesday threat with TEMPO groups at all TAF sites. As we head into Tuesday, scattered hit-or-miss showers and thunderstorms will continue to impact the region as the slow-moving upper low approaches from the north. Covered this threat with PROB30 groups for now, although later shifts may need to add prevailing or TEMPO groups for TSRA and/or SHRA. Furthermore, widespread MVFR and possibly patchy IFR ceilings will prevail from late tonight through much of Tuesday. && .ICT WATCHES/WARNINGS/ADVISORIES... Flood Watch through this afternoon for KSZ032-033-047>053- 067>072-082-083-091>096-098>100. && DISCUSSION...JWK AVIATION...ADK
