Short term (today through thursday)...
upper air analysis last evening showed northwesterly flow over Texas
between a trough to the east and ridge to the west. At the surface,
the pressure gradient was weak and winds were light and variable
across our County Warning Area. The upper level ridge will move across Texas during
the next 24 hours. The low level flow will become southeasterly
increasing moisture in the boundary layer. Subsidence will remain
strong enough to keep the weather dry today and tonight. Thursday an
upper level trough will move in from the west and combined with the
deeper moisture over the eastern half of our area may produce some
showers and thunderstorms. Chances for rain will be best over the
southeastern counties and reach as far as The Hill Country and I-37.
The best chances for rain will be during the afternoon Thursday.

&&

Long term (thursday night through tuesday)...
the upper level trough will continue to rotate through Texas Thursday
night through Saturday. We will continue to see low chances for
showers and thunderstorms with better chances during the day Friday
over the eastern half of our County Warning Area. Saturday night and Sunday a cold
front will move from North Texas through our County Warning Area. This front will
bring better chances for showers and thunderstorms to most of the
area. Breezy northerly winds behind the front will bring cooler,
drier air. Northerly flow will continue through the end of the
period keeping the weather dry. Temperatures will be near normal.
