Area Forecast Discussion National Weather Service Wichita KS 331 PM CDT Tue Sep 14 2021 .SHORT TERM...(This evening through Wednesday night) Issued at 326 PM CDT Tue Sep 14 2021 Forecast highlights the next 7 days: * Shower and thunderstorm chances this evening through tonight. * Warming trend and return to well above normal temperatures late week through early next week. * Potential for a nice cool down early to mid next week. Cumulus field continues to thicken across south-central and southeast Kansas, suggesting convergence in vicinity of the slowly approaching cold frontal zone. Combination of this convergence in concert with pooling moisture and surface heating should be sufficient for isolated to scattered thunderstorm development this afternoon through early evening across south-central and southeast Kansas. This early activity should be more on the sparse side given fairly weak convergence/lift. However, thinking thunderstorm coverage and possibly intensity will increase this evening and overnight generally south of I-70, as as a modest low-level jet impinges upon this frontal zone. Approaching shortwave energy from the northwest will also aid this festering/increasing activity. Overall combination of modest mid-level lapse rates, instability and deep layer shear supports a strong to low-end severe threat with the strongest activity before midnight, capable of 50-65 mph winds and dime-quarter size hail. Furthermore, corfidi vectors aligned nearly parallel to the frontal zone should allow for west-east training storms especially before midnight, supporting heavy rainfall amounts and localized flooding issues. Thinking the greatest potential for this would be somewhere along/near the Highway 50 or 54 corridors per latest observational and short-term model trends. Subsidence settles south across the region for Wednesday in wake of this system, which will support lowering rain chances and clearing skies Wednesday morning. Low-level thickness values suggest high temperatures will be mostly in the mid-80s. .LONG TERM...(Thursday through Tuesday) Issued at 326 PM CDT Tue Sep 14 2021 Deterministic and ensemble consensus supports a warming trend and return to well above normal temperatures once again by Thursday- Friday, and persisting through at least Monday of next week, as upper ridging builds across the western and central CONUS, and low- level southerly flow strengthens. Overnight lows will be in the 60s to low 70s, with thickness values supporting daytime highs mostly in the 90s. Normal highs this time of year are in the low-mid 80s. Synoptic pattern supports low to NIL precipitation chances through Monday, although a frontal boundary oozing into northern/central KS may support low storm chances along/north of I-70 Friday evening. Finally, while exact details differ, deterministic and ensemble consensus supports a deep trough digging across the western and central CONUS early to mid next week, with an associated strong cold front blasting southeast across Mid-America. If this scenario pans out, bonifide fall-like temperatures will spread south across the region, with lows in the 40s-50s, and highs in the 60s-70s. Could also be looking at increased thunderstorm chances in vicinity of the strong frontal zone. Still a ways out, so stay tuned for later forecasts. && .AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon) Issued at 1238 PM CDT Tue Sep 14 2021 Main aviation concern will be storm chances late this afternoon and evening. Cold front currently extends from near KMCI to just north of KHUT and finally into far southwest KS and will continue to slowly track south. Mid level warm advection has resulted in some scattered showers over central KS this morning and early afternoon and will continue for a couple more hours. Storms are expected to develop along the front generally after 21z with the most likely area of initiation between KICT and KDDC and will track east through the evening. With convection not expected to be as widespread as previously thought, just ran with VCTS at most sites and will adjust once we see where storms develop. Most of the activity is expected to be south of the area by sunrise Wed. && .PRELIMINARY POINT TEMPS/POPS...
