Area Forecast Discussion
National Weather Service Houston/Galveston TX
621 PM CST Thu Feb 23 2017

.AVIATION...
With winds expected to decouple later this evening (and mostly
clear skies already in place) we should see the development of
patchy fog/low clouds overnight across much of SE TX. However,
will have to keep an eye on winds just above the surface (cur-
rently SW/S @25-35 knots) which could keep it a more lower CIG
forecast than VIS through sunrise. These conditions should im-
prove by 15Z tomorrow, with the cold front moving into the NRN
parts of the area (CLL) just after noon. The front should move
off the coast just after 00Z. 41

.PREV DISCUSSION... /ISSUED 336 PM CST Thu Feb 23 2017/

Above normal temperatures will continue until a cold front moves
through Southeast Texas tomorrow. Before the front arrives and
cools us back down toward normal end of February temperatures,
there will be a chance of low cloud and fog formation (if winds
diminish enough) mainly late tonight through early tomorrow
morning. Dense fog advisories might be needed. We are looking at
another warm day tomorrow (highs in the 80s again for most of the
area that stays ahead of the front long enough). Moisture levels
will be too low for any shower development with the front. Cooler
weather behind the front for Friday night through Saturday night
(courtesy of a surface high ridging into our area from the
northwest and north) will not last very long. On Sunday, winds
come back around to the southeast and south as the surface high
moves off to the east and brings the area increasing clouds and
low rain chances. Current thinking has best risk for any higher
shower and thunderstorm chances north of our area Sunday night
through Monday morning. Lowish rain chances and warming
temperatures remain in the forecast until the area`s next cold
front currently in the forecast to move through on Wednesday. 42
