.DISCUSSION...
Issued at 200 AM CDT Sat Jul 12 2025

Midnight radar and satellite imagery was very busy, depicting
three separate MCSs, one over SW Nebraska, one along the
Colorado/Kansas border, and another over the Texas Panhandle.
CAMs and 00z NAM are in good agreement that a complex of rain
showers and thunderstorms will move into at least western zones
through sunrise. Severe weather appears unlikely, given
nocturnal timing and weak shear, but combining cold pools will
produce outflow wind gusts of 40-50 mph. The wet summer
continues, with areas of heavy/excessive rainfall expected.
Increased pops dramatically tonight through much of Saturday.
Showers may persist for much of daylight Saturday, best shown
by NAM solutions, and again increased pops accordingly.
Thick midlevel clouds, areas of rain, and cool advection on
light northeast winds will all work together to deliver a
welcome break from the summer heat. 00z NAM shows a net decrease
of -10C at 850 mb Saturday versus yesterday, and combined with
limited insolation, lowered temperatures this afternoon into
the lower to mid 70s for most locations. The forecast high at
DDC is now 74, a full 20 degrees below normal for mid July.
The record low max at DDC for July 12 is 68, and wouldn`t be
surprised if some locales are stuck in the 60s all day, if
clouds and rain persist per the 00z NAM solution. Most
instability will be shoved well south of SW KS today, with any
marginally severe wind/hail remaining in Texas/Oklahoma. In
fact, only included isolated thunder in the grids as modeled
instability fields are quite weak.

Of course breaks from the heat do not last long in July, and a
warming trend is expected Sunday through Tuesday. Afternoon
temperatures will return to July normals, in the lower to mid
90s, by Tuesday. SW KS is expected to remain dry Sunday through
Tuesday, and dry NBM pops reflect this.

Global models and their ensembles remain consistent, forecasting
a strong shortwave over the northern Rockies Wednesday morning,
moving to the upper Mississippi Valley Thursday morning. This
synoptic evolution will drive another summer cold front into
SW KS, with model timing consensus of frontal passage around
Thursday morning. Rain/thunderstorm chances will increase, and
afternoon temperatures will cool to the 80s, as this cold front
arrives, and both of these trends are correctly depicted by the
latest iteration of the NBM grids.

.AVIATION /18Z TAFS THROUGH 18Z SUNDAY/...
Issued at 1252 PM CDT Sat Jul 12 2025

Low MVFR CIGS were developing at KDDC with daytime mixing and
increasing moisture with height at lower levels. It is uncertain
how long this will persist; but with continued daytime heating,
VFR CIGS should return by 21-22z. Only scattered low cloud is
anticipated at KGCK and KHYS. Winds will be light and generally
10 kts or less through the period as weak surface high pressure
builds across the plains.
