Area Forecast Discussion
National Weather Service Houston/Galveston TX
1143 PM CDT Wed Apr 25 2018

.AVIATION...
A SCT-BKN stratus deck around FL020 has developed behind the
front and is translating southward per split channel satellite
imagery. Expect MVFR ceilings to impact CLL, UTS, and CXO through
08Z. Past few runs of HRRR have been consistent on this deck
breaking up as it reaches the Houston terminals, but IAH may see
an hour or two of MVFR ceilings before this happens (potentially
sometime between 07-09Z). Otherwise, front is expected to clear
GLS by 07Z with VFR conditions prevailing at all terminals after
09Z. Northerly winds near 10 knots this evening may fall into the
5-10 knot range by mid to late morning. Winds may become more
westerly or southwesterly for a period of time at GLS during the
day Thursday as a surface ridge slides into the Gulf, but a
secondary cold front looks to move across the terminals after 00Z
Friday and reestablish northerly flow.
