.SHORT TERM...
(Tonight through Saturday)
Issued at 1151 PM CST Thu Dec 4 2025

Satellite imagery shows a steady stream of high clouds across
Texas tonight with thicker low clouds beneath. This tap into
Pacific moisture is thanks to strong southwest flow aloft ahead of
an elongated trough axis. At the surface, a weak southerly flow is
trying to become established late tonight. As it does, winds
above the surface will become more southwesterly allowing the
lower cloud cover to erode a bit. While forcing for ascent is only
modest at best, areas of light precipitation are ongoing across
parts of Central and South Texas. The bulk of any light rain will
remain out of our area but we can`t rule out a few sprinkles or
very light rain across our Central TX counties through morning.
The rest of the day Friday should feature mostly cloudy skies with
temperatures ranging from the lower 50s across our east to the
lower 60s in the west where clouds will thin through the day.

Later Friday night, an influx of lower 40s dewpoints will spread
north of I-20 into relatively cooler air thanks to strengthening
southerly flow. This moisture surge will likely lead to the rapid
development of low clouds and fog, particularly north of I-20 and
across our eastern counties. As a trailing shortwave swings
through the Southern Plains, drier air will work into North Texas
from the west early Saturday and should start to erode some of
this cloud cover, however, there may be a substantial temperature
gradient from west to east depending on how long the clouds
linger. Highs may range from the mid 50s in the east to the lower
70s out west.

.LONG TERM...
(Saturday night through next Thursday)
Issued at 1151 PM CST Thu Dec 4 2025

After Saturday, the weather pattern looks to remain fairly benign
for this time of year with surface high pressure in place across
the eastern CONUS through Tuesday and mid level ridging building
across the Southwest U.S. This should keep the Southern Plains
beneath dry northwest flow aloft with little chance for
precipitation and steadily warming temperatures through the middle
of the week.

.AVIATION...
(06Z TAFS)
Issued at 1151 PM CST Thu Dec 4 2025

Widespread MVFR cigs will persist for another few hours before
drier air gradually works into the region from the west. We`ll see
the lower clouds scatter out through the early morning hours,
however, thick high cloud cover should persist for much of the day
thanks to strong southwest flow aloft tapping into Pacific
moisture. Late tonight (Fri night), areas of fog and low clouds
are likely to develop across the region and persist into Saturday
morning. This may impact the D10 airspace for several hours before
drier air eventually erodes the fog through mid morning.
