.SHORT TERM...
(Today through Sunday)
Issued at 1203 AM CST Sat Dec 6 2025

Mostly cloudy skies will still start off early this morning for
the majority of the region but will clear out quickly from the
northwest to southeast by midday or early afternoon as a more
west-northwest flow develops aloft in the wake of a minor upper
level disturbance. A light southwesterly flow develops at the
surface across much of the region as well. With skies clearing and
the southwesterly surface flow in place, expect a much warmer
afternoon across the region with highs in the low to mid 70s area
wide. A milder night should also be expected entering Sunday
morning with lows in the upper 40s to mid 50s. The coastal plains
could see patchy to areas of fog develop for Sunday morning where
the higher dew points are to reside and light winds thanks to the
relaxed pressure gradient ahead of a nearing cold front.

The cold front advances across the region through the day on
Sunday. Temperatures across the northern half of the region look
to mostly top out in the mid to upper 60s with the front moving
through by around midday. Farther to the south where the front
will take longer to push through, expect for highs to climb into
the 70s to near 80 degrees. Moderate to breezy north winds develop
behind the front with gusts up into the 25 mph range.

.LONG TERM...
(Sunday night through Friday)
Issued at 1203 AM CST Sat Dec 6 2025

A dry and slightly cooler post-frontal airmass will be in place
at least through Tuesday morning. Advective cooling into Monday
with north winds followed by radiational cooling into Tuesday
morning under clear skies and light winds will make the
temperatures most noteworthy around sunrise each morning, where
some rural locations may near the freezing mark. However, it looks
to be quite limited and for mostly locations that have already
experienced a light freeze this season. Elsewhere, mid 30s to low
40s trend common. Monday trends as the coolest day with highs
ranging from the upper 50s for the east into the mid to upper 60s
along the Rio Grande. Tuesday will see highs more solidly within
the 60s to near 70 degrees.

A southerly low-level flow returns and will slightly uptick
through midweek. This will yield to a warming trend with afternoon
highs climbing into the mid to upper 70s and low 80s. Overnight
lows become milder as well into the 40s to near 50 degrees. Skies
will trend mostly sunny each afternoon while some low cloud cover
could enter the picture east of I-35 during the morning hours. The
next front then approaches into or sometime around Friday
morning. It looks to remain rain free like the front on Sunday and
brings a slightly cooler airmass to the area into the start of
the next weekend.

.AVIATION...
(06Z TAFS)
Issued at 1203 AM CST Sat Dec 6 2025

VFR flight conditions are forecast for the period. Mid and high
level clouds will continue through early morning before clearing
from northwest to southeast later this morning into the early
afternoon. Light winds prevail with directions turning more
uniformly from the west-southwest later in the afternoon.

&&

.FIRE WEATHER...
Issued at 1203 AM CST Sat Dec 6 2025

Much warmer and rain free conditions prevail today as skies are
expected to clear out from northwest to southeast. Winds will be
light today from the west-southwest while minimum humidity will
range from around 25 percent in the Hill Country and Southern
Edwards Plateau to near 50 percent in the coastal plains. A cold
front advances across the region on Sunday bringing gusty north
winds through the afternoon into the early evening. The winds
combined with minimum humidity below 30 percent along and to the
west of highway 281 could promote locally elevated fire weather
concerns. However, the fuel dryness levels across the region are
above normal moisture and this helps alleviate the fire weather
concerns after the cool, gray, and damp past week. Southerly flow
returns into and through midweek with warmer temperatures with
humidity levels ranging from 20 to 50 percent. The next front then
looks to approach sometime into early Friday.
