.DISCUSSION... Issued at 242 PM CDT Sat Sep 13 2025
High amplitude shortwave ridging continues to remain in place over the region today. This coupled with modest WAA is continuing to allow temperatures to push well above normal with highs in the low to mid 90s and lows tonight in the upper 60s to as warm as the mid 70s in the urban core. Tomorrow, a stationary front will extend from a surface low over the Black Hills to near the MO/IL border. Widely scattered afternoon/evening storms will be possible in the vicinity of this front which may bring a few storms into the eastern CWA. In addition, tomorrow, the upper level ridge will shift just east of the area as a upper level trough digs into the west central Plains. Lead shortwaves will move into eastern Kansas bringing the potential for widely scattered afternoon/evening storms to the western CWA. Monday and Tuesday the upper level ridge will continue to reside just east of the area, with upper troughing over the western Plains. This will leave the local area under southwest flow aloft between the two features keeping temperatures well above normal with highs remaining in the low to mid 90s. weak shortwaves in the southwest flow may provide enough lift to produce some widely scattered diurnally driven storms both Monday and Tuesday. Tuesday night into Wednesday the upper level trough will move from the western High Plains into the Upper Midwest. This will force a trailing cold front through the CWA Wednesday. This will bring the next good chance for widespread showers and thunderstorms (50-60%). The pattern looks to remain active through the latter part of the work week as additional shortwaves will move across the northern Plains continuing shower and thunderstorm chances locally. In the wake of the cold front Wednesday, temperatures will return to near normal with highs in the upper 70s to mid 80s for the remainder of the work week.

.AVIATION /00Z TAFS THROUGH 00Z MONDAY/... Issued at 628 PM CDT Sat Sep 13 2025
VFR conditions anticipated to prevail with this issuance. Light S/SSW winds will become more due S overnight and through the day Sunday, with winds around 10G18kts at times. Precipitation wise, confidence not great enough to introduce PROB30s or otherwise. Mid-upper shortwave expected to keep bulk of activity to the west/into Kansas. Additionally, surface boundary expected to be over eastern Missouri, too keeping activity away from the metro sites and STJ. Will continue to monitor for any necessary adjustments next cycle or two.
