.SHORT TERM (Today through Saturday)...
Upper air analysis last evening showed south to southwesterly flow
over Texas with a ridge to the east and a trough to the west.
Water vapor satellite imagery showed mid-level moisture moving in
from the Gulf around the back side of the ridge. At the surface,
high pressure over the Gulf was keeping winds from the southeast.
In the short term, the upper ridge will continue to move to the
northeast and heights will fall over Texas. This will allow
diurnally driven convection over the eastern half of our CWA today
with isolated to scattered thunderstorms. Tomorrow afternoon
isolated convection will spread to the west to include the entire
CWA.

&&

.LONG TERM (Saturday Night through Thursday)...
The subtropical ridge will split across the southern part of the
country with a weakness developing over the southern plains. This
weakness will allow daily convection from Sunday into the middle
of next week. Rain chances will vary day to day with Monday
looking like the best chance over the widest area. Model QPF is
moderate likely due to no significant forcing, but PW does
increase to 2+ inches over the east. This value would suggest
heavy rain and it seems possible that there could be some locally
heavy rain Sunday and Monday when POPs are highest.
