201 AM CDT Wed Mar 12 2025

...STRONG WINDS AND VERY DRY AIR BEHIND A DRYLINE AND PACIFIC 
FRONT WILL RESULT IN CRITICAL TO EXTREME FIRE WEATHER 
CONDITIONS TODAY INTO THIS EVENING...

.A dryline advancing eastward this morning will quickly become 
overtaken by a Pacific front in the afternoon. Critical to extreme
fire weather conditions will develop in the wake of these 
boundaries. These conditions are expected to first develop across 
the southern Edwards Plateau midday Wednesday, then spread south
and east into the Rio Grande Plains and Hill Country by mid 
afternoon, and then potentially into the I-35 corridor late 
afternoon and early evening.

929 PM CDT Wed Mar 12 2025

...GUSTY WINDS AND VERY DRY AIR BEHIND A DRYLINE AND PACIFIC
FRONT WILL RESULT IN CRITICAL FIRE WEATHER CONDITIONS FRIDAY 
AFTERNOON AND EVENING...

.A dryline and Pacific cold front are expected to sweep across 
South Central Texas during the day Friday. Strong westerly winds 
and very dry air behind the front will likely bring critical fire 
weather conditions across much of the region. These conditions 
will quickly spread eastward, becoming widespread along and west 
of the I-35 corridor by noon. Sustained westerly winds of 15-25 
mph are expected. Peak gusts up to 45 mph are expected over the 
southern Edwards Plateau and Hill Country, with gusts of 25-35 mph
along the I-35 corridor and Rio Grande Plains. Relative 
humidities will be very low across the entirety of South Central 
Texas with widespread values of 5-15 percent along and west of the
I-35 corridor. Winds are forecast to diminish after sunset.

Area Forecast Discussion
National Weather Service Austin/San Antonio TX
1234 PM CDT Tue Mar 11 2025

...New AVIATION...

.SHORT TERM...
(Today through Wednesday)
Issued at 231 AM CDT Tue Mar 11 2025

Key Messages:

- Mainly dry with climbing temperatures and increasing winds

- Fire weather threat returns today, becomes critical Wednesday

A near to slightly below seasonably cool start this morning warms
quickly with the help from ample sunshine and with an increasing
south-southwesterly flow. The winds are forecast to be strongest
across the Hill Country into the I-35 corridor with gusts near or
above 25 mph. The uptick in the winds will promote returning fire
weather concerns. Specifics on the fire weather threat could be
found in the fire weather discussion below. Highs will top out in
the 80s across most locations while a few low 90s are possible in
the Rio Grande Plains. Wind speeds should lay down some entering
tonight but may not fully decouple as a nocturnal low-level jet
develops ahead of the approaching storm system on Wednesday. Low
clouds will also spread across portions of the region into early
Wednesday morning. With the winds, stratus looks to remain more
favorable than fog. The morning lows will be in the 50s into
Wednesday.

The storm system arrives Wednesday. It will bring a dryline east,
which then gets overtaken by a Pacific front. This will bring in
strong west to northwesterly winds and the reinforcement of even
drier air. Winds will be strongest west of I-35 where sustained
winds of 15 to 30 mph establish with higher gusts. This leads to
critical fire weather as illustrated by the current Fire Weather
Watch that is in effect. More details could be found in the fire
weather discussion below. East of the dryline, across our far
eastern-northeastern most counties, there will be a very low end
(~10%) chance for development of a stray storm during Wednesday
afternoon. Greater chances continue to align farther northeast
across the Fort Worth and Houston CWAs. However, if a storm can
establish across our region, there could be sufficient instability
and shear in place, to allow for strengthening. Otherwise, expect
continued rain free conditions across the area underneath sunny
skies with even hotter temperatures. Afternoon highs climb to the
upper 80s and low to mid 90s. The Rio Grande Plains will be even
warmer into the upper 90s or even above the century mark.

.LONG TERM...
(Wednesday night through Monday)
Issued at 231 AM CDT Tue Mar 11 2025

Key Messages:

- A Critical Fire Weather event could impact all of South Central
  Texas Friday into Saturday

- Elevated to near critical fire weather conditions are possible for
  portions of the area each day through Monday

There looks to be a relatively late arrival of the wind shift and dry
air intrusion over Burnet County late Wednesday, so there could still
be fire weather concerns lingering into the early evening.

Light winds develop by Thursday morning, and then a quick return of
dry southerly winds sets up a robust warm-up for Thursday afternoon.
As west counties turn up the winds faster, there could be
additional fire weather concerns. The bigger fire weather event
follows on Friday into Saturday and will be discussed below. A
partial surge of Gulf humidity reaches inland but doesn't last long
as large Friday upper low and trough brings the next dry Pacific front.
This pattern may pack almost as much punch as the one from March 4,
and there will likely be a wind advisory for most of the area. Temps
will still be warmer than normal from the Friday west winds, but a
broadening of the upper trough over TX will bring a prolonged NW wind
that doesn't tamper down until Sunday. Somewhat seasonal
temperatures are depicted for Saturday through Sunday despite plenty
of sunshine. Chilly morning lows are shown for Monday morning, but
southerly return flow winds bring another fire weather concern day.

&&

.AVIATION...
(18Z TAFS)
Issued at 1232 PM CDT Tue Mar 11 2025

VFR conditions under clear skies this afternoon and evening. A period
of low stratus is expected along and east of the I-35 corridor
09Z-16Z Wednesday, producing MVFR to IFR ceilings. SW to SE winds
this afternoon and evening, with gusts in the afternoon around
20-25KT along the I-35 corridor and across the Hill Country.

&&

.FIRE WEATHER...
Issued at 351 AM CDT Tue Mar 11 2025

South-southwesterly winds increase into and through the afternoon
across the region. Winds will be breeziest over the Hill Country
into the I-35 corridor at 15 to 20 mph with gusts around 25 mph.
Elevated to near critical fire weather will establish in the Hill
Country and the northern I-35 corridor as these winds overlap
minimum relative humidity levels between 17 and 17 percent. As a
result, a Rangeland Fire Danger Statement was issued across those
locations from noon through 7 pm CDT. The humidity levels are to
recover tonight and wind speeds subside as well. Wednesday will
feature a dryline that moves eastward into the region before
becoming overtaken by a Pacific front. Critical fire weather
conditions develop in the wake of these boundaries. Winds become
strong out of the west-northwest at 15 to 30 mph with even higher
gusts up to around 40 mph. Minimum humidity levels behind these
boundaries will fall as low as the upper single digits and teens.
The Fire Weather Watch remains in effect with a couple of small
changes. We added Blanco, Kendall, and Medina Counties. We also
extended the watch two additional hours through 9 PM CDT.

Another significant fire weather event is depicted for friday as the
strongest portion of a compact Pacific upper low swings through North
TX. This places those strong mid-level jet streak winds over Central
TX once again, potentially leading to a widespread critical fire
weather event, and a potential for extreme conditions. It remains a
bit too far in the future to go into specifics, but this will likely
exceed the impacts of the Saturday Red Flag day or the one we expect
tomorrow. While the wind forecast may not be as high-end as what was
experienced last week, there will probably be a more severe RH factor
due to hot temperatures, and continued drying of vegetation fuels
could make ignition potential higher.

Return flow and lighter north wind events surround this larger event
each day through Monday as discussed some more in the long term
section. Rain cannot get here soon enough.
