.SHORT TERM (Today through Wednesday)...
Upper air analysis last evening showed a trough from the Great Lakes
to east Texas with west to west-northwesterly flow over us. At the
surface, there was a stationary front over east Texas with an ill
defined pressure field over our CWA with winds light and variable.
Ongoing convection along several mesoscale boundaries was
dissipating. A shortwave trough will move through the pattern today
bringing another chance for showers and thunderstorms. PW is forecast
to be 1.5-2.0 inches so locally heavy rain is possible with
convection this afternoon and evening. The subtropical ridge will
begin to build back over Texas from the west. This will push rain
chance to the east for Wednesday.

&&

.LONG TERM (Wednesday Night through Monday)...
The subtropical ridge will continue to slowly build to the east
keeping most of our CWA dry Wednesday night through Friday. Slight to
low end chance POPs will be confined to the area southeast of I-35.
The push of the upper level ridge will lower PW values, so heavy rain
will be less likely. By Firday night the ridge will be dominant and
no rain chances will remain. The forecast will be for dry weather
through the end of the period. Temperatures will climb back to above
normal by Friday and then level off through the end of the period.
