.DISCUSSION... Issued at 343 AM CDT Mon Oct 6 2025
Scattered showers and few embedded thunderstorms continue to move across north-central and far northeastern Kansas this morning bringing beneficial rainfall to the region. This is all in response to a weak mid-level wave and surface trough that is currently tracking across eastern Kansas with additional help from the proximity of the right entrance region of the upper level jet and low level WAA within a 25-30 knot LLJ. Through the remainder of the morning and afternoon, scattered showers and some isolated thunderstorms will continue across eastern Kansas, with chances slowly spreading into east-central Kansas as the surface trough tracks southeast. CAMs depict a slight lull in coverage by the afternoon as increasing ML subsidence and some dry air mixing in build in from the southwest. Temperatures today will reflect the precipitation and CAA from the north as areas across northern and central Kansas top out in the 60s and low 70s. Areas along and south of I-35 will see the lingering southerly flow and lack of precipitation keep temperatures topping out in the low to mid 80s once again.
By this evening, low level convergence within the 850- 700 mb layers increases as some mid-level vorticity lobes advect across Kansas and help to return widespread precipitation chances to eastern Kansas. Appreciable instability seems to stay south of the area so expecting mostly rain showers, but a few rumbles of thunder could be realized with taller updrafts Monday night and early Tuesday morning. Ensemble guidance shows additional accumulations tonight around 0.25"-0.75". Forcing comes to an end around sunrise Tuesday morning with mid-level subsidence overspreading eastern Kansas for the remainder of the morning. A 1028mb surface high advects in from the north through the day, slowly brining in clearer skies from the north. Expect high temperatures to top out in the mid to upper 60s. Similar conditions will be expected through the day Wednesday with mostly clear skies and temps in the upper 60s and low 70s.
The remainder of the week will see temperatures slowly warming back into the low 80s with some small chances for light rain Thursday morning (20%). Long range guidance begins to hint at a large trough entering the central US by Sunday/Monday that could bring our next chance of widespread precipitation and perhaps another airmass change.

.AVIATION /06Z TAFS THROUGH 06Z TUESDAY/... Issued at 1247 AM CDT Mon Oct 6 2025
All sites should remain VFR for the first 6 hours of the period until MVFR stratus and precipitation build across the sites. Updated best thoughts on timing of precipitation with KMHK seeing the best chance for precipitation through 7 AM this morning. A wind shift behind the surface cold front will move through the sites over the first few hours of the TAF, but winds should stay light until later in the TAF. In addition, expecting a slight lull in precipitation in the mid afternoon hours before another wave of showers, possibly a few rumbles of thunder, build back in Monday evening and into Tuesday morning.
