Short term (tonight through Wednesday night)...
upper air analysis this morning showed a trough extending from the
middle Mississippi Valley to south Texas. At the surface...high
pressure was centered over the Gulf and winds were from the
southeast. The upper trough was causing showers and thunderstorms
that were mainly east of our County Warning Area with only isolated cells in our
eastern counties. This should continue this evening as the upper
trough remains in place. This pattern will change very little
during this period...so there will be slight chance for
convection again tomorrow afternoon and evening.

Long term (thursday through tuesday)...
Thursday the upper level ridge will build back over Texas from the
west. Deep layer moist flow will continue over the southeastern
counties and this may be sufficient to produce isolated showers
and thunderstorms during the afternoon and evening through the
rest of the period. Temperatures will be near to slightly above
normal during the entire forecast.
