.DISCUSSION...
Issued at 252 PM CST Tue Dec 2 2025

Northwest upper flow regime from the Pacific Northwest to the
central CONUS has backed in the short term with cirrus making its
way over the central Rockies downstream of an upper wave digging
over California. Lee troughing has allowed for decent warm-air
advection over the snow field over much of the area with temperatures
at to well above freezing at 19Z.

Continued south to southwest flow near the surface under increasing
high cloud should lead to steady temperatures for the late evening
and overnight. Most guidance indicates a few weak mid-level waves
traversing the area later tonight and again Wednesday. Forcing for
ascent looks weak and low-level moisture is largely lacking, though
does increase for a several hour period behind a cold front that
will surge southeast across the area late tonight into early
Wednesday afternoon. The coincidence of these waves with the greater
low-level saturation is not ideal but there is enough concern to
mention trace precip; the vast majority of models fail to generate
measurable precipitation. Temperatures behind the front may fall in
the afternoon for central and northern areas given strong 925 mb CAA
and little insolation. Overall, temperatures with this next front
have trended a bit warmer than earlier but lows still approach
record low values at TOP with wind chill in the single digits above
0 much of Wednesday night and early Thursday morning.

Northwest flow persists into early next week though becomes more
zonal, which should keep significant cold surges more in check. A
modest wave around Saturday night will need to be monitored, but
precipitation chances look low beyond Thursday.

.AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/...
Issued at 1148 AM CST Tue Dec 2 2025

VFR conditions are expected through the bulk of this forecast.
Modest south to southwest winds should be the rule until a cold
front arrive late, with timing looking to bring in into MHK
around 16Z and ushering in MVFR stratus. Very light
precipitation can`t be ruled out late in the forecast as well. A
modest low-level jet forms overnight but speeds look too low to
include.
