.DISCUSSION... Issued at 252 AM CDT Sun Sep 14 2025
Mid to upper level ridging remains over the area with troughing exiting the Four Corners Region. As the axis of the ridge has shifted slightly to the east, high temperatures this afternoon will be a few degrees cooler than yesterday. Highs for today will range in the upper 80s to mid 90s. A weak surface boundary to the east of the area could provide just enough lift to spark a few showers and storms late this afternoon into early Monday primarily for areas east of I-35. Simultaneously, the previously mentioned troughing exiting the Four Corners Region will deepen and begin to track to the northeast along the western edge of the ridge over our area. A H500 shortwave will bring chances for isolated to scattered showers and storms primarily for eastern KS and northwestern MO late Sunday afternoon into early Monday morning. In regards to both rounds of showers and storms, weak instability (below 500 J/kg), limited shear (bulk shear values up to 25 kts), and an overall unfavorable environment for severe weather will keep severe chances virtually non-existent. The consensus for most hi-res models suggest showers and storms dissipate during the predawn hours on Monday. The 00Z HRRR seems to be a little overzealous in regards to coverage and timing compared to the other models with more widespread showers and storms and keeping precip chances around until late Monday morning.
For Monday and Tuesday, the mid to upper level ridge shifts just to the east of the area as a couple of shortwaves move along the western edge. These shortwaves could provide a few spotty chances for afternoon/evening showers and storms. Otherwise, high temperatures remain in the upper 80s to low 90s as the ridge maintains its influence over the area. Approaching mid-week, stout mid to upper level troughing entering the Great Plains Region will gradually push a surface cold front through the area bringing better chances for widespread showers and storms Wednesday. On the backside of the surface cold front, expect high temperatures much closer to seasonal averages for the second half of this week with highs in the mid 70s to low 80s. Multiple shortwaves in association with the mid to upper level troughing will give us several chances for showers and storms for the second half of this week into the weekend.

.AVIATION /12Z TAFS THROUGH 12Z MONDAY/... Issued at 635 AM CDT Sun Sep 14 2025
VFR conditions prevailing at all locations with the exception of KSTJ. Conditions at KSTJ are expected to improve as daytime heating commences, dissipating the fog. Winds will remain out of the south- southwest for all terminals. Occasional gusts to 17-19 kts are anticipated later this morning through the afternoon. This evening into tonight, there will be low-end chances for showers and a few isolated thunderstorms primarily for KSTJ, KMCI, and KMKC. For now, confidence is too low on timing and location of storms to add a PROB30 group. Winds will weaken this evening as diurnal mixing diminishes.
