Area Forecast Discussion
National Weather Service Houston/Galveston TX
408 AM CST Mon Jan 22 2018

Front is in the process of moving thru the area. Lack of
instability and some capping has limited areal coverage and
intensity. Precipitation should be near or off the coast by
sunrise...taking the sea fog with it. Clearing skies and a much
drier airmass will filter in during the day allowing RH`s to dip
into the 25-30% range during the day with nw winds 10-20 mph.
Elevated fire weather conditions are possible.

Dry, seasonable weather will persist into the mid-late work week
time period with surface high pressure dominating area wx.
Moisture levels and rain chances will increase going on into the
weekend as onshore winds resume as the high moves off to the east.
The next western trof will advance into the Plains and send a
cold front and associated precip through the area sometime
Saturday. 47


Sea fog/showers currently lingering over the area is expected to
move out by mid morning with the passage of the weak cold front.
Winds behind this front not terribly impressive per obs upstream
but with the continued CAA behind this boundary, we could see an
uptick with winds/seas over the offshore waters this afternoon.
An SCEC has been issued for the 20-60 nm coastal waters for this

As the associated surface high builds down into the region tonight
and then makes a slow sweep across the southern states, winds will
be shifting to the east by Tues and persisting through much of the
upcoming week. However, winds/seas across the offshore waters will
likely continue to remain elevated and Caution flag criteria could
persist through this week. SE winds expected to return to the area
late Thurs/Fri ahead of the next cold front that is still forecast
to move into the Gulf waters late Sat. 41


Scattered showers still possible through the rest of this morning
with the passage of the cold front. Sea fog will also remain prob-
lematic at GLS through mid morning. However, we are and will keep
seeing improving conditions from the NW as the morning wears on.
VFR should prevail areawide by 18Z. No CIG/VIS issues for tonight
or tomorrow. 41
