.LONG TERM... (Tuesday through Sunday)

Tuesday and Wednesday look to remain quiet with surface high
pressure drifting from East Texas toward the FL panhandle by
Wednesday evening. Sunshine should prevail on Tuesday with some
increase in clouds for Wednesday. 850 mb temperatures warm as well
so MaxT values should warm from the low/mid 60`s on Tuesday to
near 70 degrees on Wednesday. Thursday will be even warmer as 850
mb temps warm to near 14.5 C. PW values remain around an inch or
less with a stout cap in place so no rain is expected. MaxT values
on Thursday could warm into the mid/upper 70`s. The first in a
series of fast moving cold fronts will push through the area early
Friday (maybe late Thursday night). It should knock temperatures
back down into the 60`s for high temperatures. PW values climb to
around 1.30 inches so there could be some showers along the front
but upper level support is weak so not expecting much coverage.

The surface high that builds into the region behind the front will
move east so quickly that a light return flow will become
reestablished on Friday night with a weak onshore flow persisting
on Saturday. A much stronger cold front will then move across SE
TX Saturday night with significantly colder temperatures for next
Saturday night and Sunday. 43
