(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 && .PRELIMINARY POINT TEMPS/POPS...
