.DISCUSSION...
Issued at 230 AM CST Fri Nov 8 2024

Water vapor imagery overlaid with 500 mb heights shows a strong
upper level low over New Mexico this morning with a mid level
speed max rotating through the base of the trough across
northern Mexico into western Texas. Forcing for ascent and low
level warm air advection has yielded widespread convection
across much of the Southern Plains, with high level cloud cover
beginning to overspread our region from the southwest. Surface
high pressure remains in place over the region this morning,
with nearly calm winds and 2 AM temperatures ranging from the
upper 30s to mid 40s.

The aforementioned upper low over New Mexico and associated
trough will eject to the northeast today, with the upper low
progged to be centered over the TX/OK panhandles by late
afternoon. High level cloud cover should only increase
throughout the day today, with dew points also increasing
several degrees. A relatively large precipitation shield should
approach the area from the southwest this afternoon, and some
drizzle or even light rain will be possible this evening for
southwestern portions of the CWA. Widespread showers should
finally overspread the area from SW to NE overnight tonight into
early Saturday morning as the low occludes over western Kansas
and the occluded front lifts northward toward Missouri. A few
rumbles of thunder may be possible as there may be just a little
bit of instability available, especially toward the Ozark
Plateau. Rain should end from SW to NE by late Saturday
afternoon. Total rainfall amounts are currently forecast to
range from as much as 0.75" toward Bates County MO/Linn County
KS to as low as around 0.33" across NE Missouri.

By Sunday, the low should have progressed northeastward into the
Great Lakes region, with zonal west to east flow taking hold
over Kansas and Missouri. This should result in clearing skies,
slightly breezy westerly winds, and high temperatures in the
upper 50s to mid 60s for Sunday afternoon. Generally tranquil
weather conditions should persist through Tuesday with daytime
highs in the upper 50s to mid 60s.

Chances for rain return to the forecast next Wednesday as models
suggest another trough potentially moving into the Central
Plains, although the ECMWF and GFS currently differ quite a bit
in terms of the details of this trough. For now, slight chance
to chance PoPs (20 to 40 percent) are in the forecast for
Wednesday morning into Wednesday afternoon.

.AVIATION /18Z TAFS THROUGH 18Z SATURDAY/...

Primary aviation focus will be on the arrival and impacts of
rainfall overnight tonight through Saturday morning. Currently,
mid to high VFR ceilings will continue to spread across the
region through the afternoon and evening. Anticipate rainfall to
arrive at sites between 05 to 06Z. MVFR ceiling and vis will
persist within expected showers, with IFR ceilings developing
before sunrise. Some improvement to conditions will exist late
in the period, as the system begins to lift east and northeast
of the terminals through 09/18Z.
