Update...
cloud cover continues to spread slowly southward across the region
this morning. The most persistent cloud cover is expected to
remain over The Hill Country and adjacent portions of the northern
I-35 corridor. This cloud cover will keep high temperatures down in
the low to middle 60s today. In addition...a few light showers may
affect areas along and north of a Fredericksburg to San Marcos to
La Grange line. Any rainfall amounts will remain very light.
Finally...north to northwesterly winds will continue and based on
recent observations and model data...we have increased wind speeds
for the remainder of today.

Aviation...
little change in the taf package from the 06z issuance. MVFR ceilings
are currently observed east of Interstate 35 with aus just having
gone sct030. Models still show the MVFR stratus to the north of
the area filtering down by middle morning and dropping the I-35
terminals to high end MVFR. VFR conditions will return to the I-35
terminals this evening with drt staying VFR through the period.
The big story today will be the winds which will be out of the
north gusting up to 25 knots at times.

Short term (today through wednesday)...surface trough/front has
moved through the central and western County Warning Area...and will continue
south and east through the morning with north to northwest winds
developing. Middle and upper level low was centered between Abilene
and Lubbock early this morning...and will move east through North
Texas this morning and into arklatex region by later afternoon.
Middle level vorticity pinwheeling around south side of low and band of
higher middle level moisture will generate a few showers...possibly
skirting through far northern areas of the County Warning Area today...primarily
north of a Llano to Austin to Giddings line. Otherwise cooler
with clouds filtering in from the north...and breezy in some
locations. Highs today only in the middle and upper 60s across The
Hill Country and low to middle 70s elsewhere.

As the low pulls away tonight and Wednesday deeper and drier
northwest flow will develop. Cool morning start on Wednesday in
the upper 40s to middle 50s...rebounding into the middle and upper 70s
in the afternoon with less clouds than today.

Long term (wednesday night through monday)...weak ridging aloft
builds over the region Thursday into Friday...with weak low level
south to southwest flow. This will produce mostly clear conditions
Thursday through Saturday with continued cool mornings...but
afternoon highs in the 80s. Low level moisture increases Sunday
and Monday...with lows modifying back to seasonal norms and a
return of morning stratus. Models hinting at possible convection
in higher terrain of Mexico and West Texas along dry line Sunday
afternoon and night...possibly making it into Val Verde County.
Better chances for precipitation come Monday into Tuesday of next week as
moisture continues to increase and next southern stream shortwave
approaches from the west.
