.DISCUSSION... Issued at 219 PM CDT Fri Sep 5 2025
A band of mid level convergence will gradually shift southward this evening, with the accompanying rain ending at Dodge City by 5 to 6 pm and 7 to 8 pm at Coldwater. With clearing tonight, expect temperatures to fall into the 40s in many places. Residual low level moisture will keep temperatures from bottoming out too low, but mid to upper 40s are likely.
The upper level trough over the upper Midwest and Great Lakes will gradually move eastward, taking the cool weather with it. A warming trend will commence Saturday afternoon, with highs slowly recovering into the upper 70s to lower 80s Sunday and mid 80 to upper 80s by Tuesday. Readings could touch 90 in a few places by mid to late next week; but the moist nature of the low level air mass and lack of downslope flow will prevent temperatures from getting much warmer than that.
Potential instability will exist starting Monday given the diurnal heating and moisture. A weak shortwave trough on Monday could create enough low level convergence for isolated strong to severe t-storms late in the day. However, the 00 UTC ensemble suites show a very small chance (10-20%) of .25" or more of rain; and this makes sense based on the expected isolated nature of storm cells. Tuesday will likely be dry given the lack of forcing mechanisms; but an isolated t-storm could still develop given the abundant low level moisture and potential instability. An upper level trough over the Desert Southwest will gradually approach the Plains by next Wednesday through Friday, promoting surface troughing and weak lift. Given the abundant greenery still in existence, promoting fluxes from the ground in addition to moisture advection from the south, there should be enough instability for t-storms. These storms could be strong to severe given the expected robustness (for this time of year) of the upper level trough and associated wind field, along with upper level divergence. Expect the areal coverage to start out low Wednesday evening and then become scattered to perhaps numerous by Friday as mid level cooling arrives. That said, the various ensemble suites show only slight chances for rains of .25" or more and the focus is more to the north of Kansas. But this is based on the 00 UTC model ensemble suites and later model runs could change. Keep in mind that although area averaged rainfall could be low, the convective nature of it could result in localized heavy amounts. Bottom line is that any precipitation will be isolated at best through Thursday, with better chances after that into Saturday.

.AVIATION /18Z TAFS THROUGH 18Z SATURDAY/... Issued at 117 PM CDT Fri Sep 5 2025
A band of rain will move across KDDC/KLBL and KGCK through 23z. CIGS will stay in the MVFR/VFR range despite the continuous rain. Drying will occur by 23-01z as weak surface high pressure settles across the high plains. Expect light winds through the period given the weak pressure gradient.
