Area Forecast Discussion...UPDATED
National Weather Service Austin/San Antonio TX
553 PM CST Fri Jan 16 2026

...New AVIATION (00Z TAFS)...

.KEY MESSAGES...

- Fire weather concerns continue Friday and Saturday.

- A widespread freeze in store Saturday night into Sunday morning
  with lows mainly in the 20s.

- Rain chances return to most areas late Tuesday into early
  Wednesday, with the higher rainfall amounts aimed at the coastal
  plains region.

.SHORT TERM...
(Tonight through Saturday night)
Issued at 1248 PM CST Fri Jan 16 2026

Early afternoon observations show temperatures have warmed into
the 60s to near 70 across south central Texas as a cold front
drops southward through western and north Texas. The front will
continue to move southward this afternoon and cold air advection
will halt or reverse the morning temperature trends over the
southern Edwards Plateau into the Hill Country. These areas are
still on track to peak in the lower to mid 60s, while plenty of
sunshine will boost temperatures into the upper 60s to mid 70s
elsewhere.

Behind the cold front, gusty north winds will persist through most
of this evening, then gradually diminish into Saturday morning.
Cold air advection will be enough to drop lows to at or below
freezing over most of the Hill Country and southern Edwards
Plateau, with mid 30s to near 40 elsewhere. On Saturday, high
pressure remains intact and strengthens during the late morning
and afternoon as another surge of cool air drops into the southern
U.S. plains. Highs will peak in the 50s for most locations, except
near 60 degrees along the Rio Grande. The gusty north winds and
dry air will continue to result in increasing fire weather
concerns on Saturday. Please see the below Fire Weather section
for more information.

Northerly winds remain gusty through early evening on Saturday,
then decrease through the overnight hours. With very dry air in
place (dewpoints in the single digits and teens) and decreasing
winds, radiational cooling will take place. Look for overnight
lows in the 20s for most spots, with some upper teens possible in
the wind-protected valleys of the Hill Country. A Freeze Warning
will be needed for those counties yet to see a widespread freeze
this year.

&&

.LONG TERM...
(Sunday through next Friday)
Issued at 1248 PM CST Fri Jan 16 2026

Highs on Sunday will nudge upward slightly as south to southwest
winds quickly return during the afternoon hours. We still expect
temperatures to remain below climatological normals for this time
of year, with mid 50s to lower 60s in store. Southerly flow in the
lower levels continues into Monday, but another front is noted
across north Texas. Will monitor this front for the possibility of
lower daytime highs across portions of the Hill Country eastward
into the I-35 corridor from near Austin northward. We opted to
bump cloud cover up a bit across the coastal plains as some
moisture begins to move northward.

Some weak disturbances will move in from the southwest and this
will aid in some light rain developing over the Rio Grande plains
south of Del Rio Tuesday morning. Rain chances (albeit initially
fairly low) will gradually spread east and northeast into the I-35
corridor and coastal plains by Wednesday morning. For now it
appears the best opportunity for rain will occur Wednesday
afternoon and evening over the coastal plains region where
moisture levels and stronger warm air advection will align. Rain
chances will largely shift east of the region Thursday, with
expected total rainfall amounts ranging from near 0.25" along I-35
to near 1" in the coastal plains. Zonal flow aloft will result in
a warming and drying trend on Thursday and Friday.

.AVIATION...
(00Z TAFS)
Issued at 534 PM CST Fri Jan 16 2026

Wind will be the primary concern over the forecast period with
frequent gusts of 22-28 kts. Despite a slight weakening of wind
speeds after 06Z, gusts above 20 kts will quickly return,
particularly at SAT and SSF where gusts may not ever truly subside
until outside this forecast. AUS may see a lull between 06Z and
15Z, but gusts above 20 kts return after 15Z Saturday. DRT will
see winds subside rather quickly this evening and they should
remain gust-free through the rest of the forecast period. VFR
ceilings are expected.
