.DISCUSSION...
Issued at 141 PM CST Sat Nov 14 2026

Another cool day is prevailing today as a surface ridge axis resides
over the eastern CWA providing for weak mixing. This will aid in
holding highs in the mid 40s to near 50. The surface ridge axis will
slowly slide east of the CWA tonight however, winds will generally
remain light under filtered high clouds allowing low to fall back
into the mid 20s to near 30. Tomorrow, northerly flow aloft relaxes
as the surface ridge slides east of the area and weak WAA gets
underway. This will allow highs to rise into low to mid 50s. Monday,
upper level ridging will build over the central CONUS in response to
a upper level trough digging into the west coast. This coupled with
continued weak WAA will lift highs into the mid 50s to near 60.

The warming trend that begins today will continue through mid-week
as Tuesday the upper level ridge axis builds directly over the area
with modest WAA getting underway. This will raise highs into the mid
50s to lower 60s. On Wednesday, the aforementioned upper level west
coast trough will be moving through the Plains states with an
attendant Pacific front also moving through the Plains. Strong WAA
out ahead of the front with provide a breezy but mild day with highs
in the 60s. Wednesday night a weakened upper level trough will move
through the region pushing a weak front through the forecast area.
Moisture will be very meager out ahead of this front however, a few
widely scattered light showers will be possible. Thursday, zonal
flow aloft coupled with surface high pressure will keep highs held
in the 60s. Thursday into Friday a upper level trough will quickly
move from the west coast into the eastern Rockies. This will push an
attendant surface cold front into the western Plains on Friday.
Another day of strong WAA out ahead of this front on Friday will
drive highs into the mid 60s to lower 70s. Friday night into
Saturday, the cold will move through the area providing the chance
for scattered showers and thunderstorms.
