.SHORT TERM...
(Today through Friday)
Issued at 328 AM CDT Thu Mar 28 2024
Some areas had wetting rains on Wednesday. As a result, patchy fog
is possible early this morning due to wet soils. Cold temperatures
will allow fog to also develop along some river valleys. Any fog
will burn off a little after sunrise.
Upper level ridging drifts overhead as surface low pressure deepens
in the Plains. Southerly lower level flow returns today and
increases tonight into Friday as pressures continue to fall leading
to breezy to locally windy conditions. After a chilly morning,
temperatures trend above normal. A moistening trend begins leading
to patchy low clouds and fog overnight into Friday morning.
Otherwise, just some high clouds are expected. Meanwhile, elevated
fire weather conditions continue out west for one last day. See the
Fire Weather Section below.

.LONG TERM...
(Friday night through Wednesday)
Issued at 328 AM CDT Thu Mar 28 2024
The first half of the long term period will be dominated by zonal
flow aloft and southeasterly flow in the low levels through the
weekend. This will mean dry weather with warming temperatures.
Temperatures will increase a few degrees each day reaching their peak
Monday when both lows and highs will be well above normal. Highs
Monday may approach records over the western half of the CWA where
they will range from the upper 80s to near 100. A pattern change will
begin during the day Monday as an upper level trough moves through
the southwestern states and brings southwesterly flow over TX. At the
surface a cold front will move through west TX reaching our western
border by the afternoon. The front will move through our CWA Monday
night and bring low chances for showers and thunderstorms to much of
the area Monday night. Models show no rain chances for the Rio Grande
and southern portion of the CWA. Breezy northerly winds will move in
behind the front Tuesday bringing cooler, drier air. Highs Tuesday
will be around ten degrees lower than Monday and will drop another
five degrees Wednesday.

.AVIATION...
(12Z TAFS)
Issued at 626 AM CDT Thu Mar 28 2024
Satellite imagery shows BR has formed along parts of Colorado River,
including near KAUS and have maintained TEMPOs through 14Z there.
Otherwise, VFR flying conditions prevail today through this evening.
Shallow moisture returns and have maintained IFR/LIFR CIGs with
reductions to VSBY overnight at the I-35 airfields. Expect it to mix
to VFR later Friday morning. VRBL winds 5 KTs or less, except
drainage NW at KSAT and W at KAUS, will become S to SE 5 to 10 KTs
later this morning, then increase to 10 to 17 KTs and gusty at KDRT
later today and the I-35 airfields tonight.

.FIRE WEATHER...
Issued at 328 AM CDT Thu Mar 28 2024
Minimum humidities in the teens to lower 20s continue in Val Verde
County and portions of Edwards, and Kinney counties this afternoon.
Winds will be lower (10 to 15 mph) at time lowest humidity compared
to last couple of days with the strongest winds across Val Verde
County. Much of Kinney county and very small portions of Val Verde
and Edwards counties had wetting rains on Wednesday. Forecast fire
danger and fuel moistures (dryness, 10 and 100 hour fuels) focus the
threat on Val Verde County. Taking all this into account, will hold
off on issuance of a Rangeland Fire Danger Statement. However, later
forecasts could issue one for Val Verde County should conditions
warrant.
