.DISCUSSION...
Issued at 237 PM CDT Sat Apr 26 2025

Through tomorrow: The radar scope is much clearer today as
shortwave upper ridging shifts across the area, but isolated
diurnal showers and perhaps a thunderstorm remain possible this
afternoon given the almost summerlike warm, humid airmass. This
activity should quickly diminish with the loss of daytime heating.
The next feature of interest to keep an eye on is the complex of
showers and thunderstorms extending from eastern OK into north TX.
As the associated mid level shortwave works eastward tonight into
Sunday, we`ll be watching this complex move toward our
northwestern areas later tonight. High res guidance consensus has
been for this activity to be on a weakening trend, but it`s
possible showers or storms could make it into our southeast
AR/north LA/MS Delta areas mainly after midnight. The remnants of
this complex and related outflows may also be the main driver of
convection on Sunday, though timing and coverage should still be
mostly diurnally driven.

Monday through next Saturday: Upper ridging will temporarily
build in, resulting in a break in rain chances for a few days.
With less rain, it will be warmer. High temperatures may approach
90F in some areas, which is quite above average and may approach
records at some sites.

During the middle to latter portion of the week, upper troughing
will begin to expand into the central CONUS, with increasing
confidence in that trough making sufficient south and eastward
progress to bring a cold front through the area late Thursday into
Friday. There may be sufficient overlay of deep shear and
instability for some stronger storms ahead of this front. While we
aren`t currently highlighting a severe threat, we will continue
to keep an eye on this time frame for a potential outlook.

For now, next weekend is looking dry in the wake of the front.

.AVIATION...
(18Z TAFS)
Issued at 1239 PM CDT Sat Apr 26 2025

Scattered low to mid level clouds are expected this afternoon.
Clouds have been slow to erode in the east/northeast, but are
showing signs of eroding on satellite. Have maintained ceilings at
MEI and GTR for just a while longer through 1830z. Clearing skies
tonight across the south should allow for some fog development
tomorrow morning. Any fog that does develop should clear around
mid morning. Further north, cloudcover should limit fog potential,
but a few areas of MVFR ceilings are possible ahead of an
approaching disturbance. Few rain showers are possible in the
northwest tomorrow morning, maintaining into the afternoon. Winds
will be light and variable under high pressure, but should shift
from the east southeast by tomorrow morning./SAS/
