Area Forecast Discussion
National Weather Service Houston/Galveston TX
1152 PM CST Wed Jan 10 2018

.AVIATION...
The KHGX VAD wind profiler shows winds below FL020 beginning to
veer this evening and the IFR deck that had begun developing near
the terminals has dissipated in response. Have made some
considerable changes to the ceiling forecast for the 06Z TAF in
response with RAP VWP progs indicating this veered profile will
only continue through the overnight hours and keep ceilings VFR.
Cannot rule out a brief MVFR deck developing towards dawn as a
shortwave in the lower levels translates across the region from
the west with a few sprinkles also possible as this happens.
Increasing forcing from a prefrontal trough will result in
scattered showers and MVFR ceilings developing near the terminals
mid to late morning, with the arrival of an upper trough and
associated cold front providing enough instability for isolated
TSRA near CXO, IAH. HOU, SGR, and LBX between 19-23Z. Expect
ceilings to gradually lift and clear behind the front with
southerly winds 5-10 knots ahead of the front increasing to 15-25
knots behind the front and becoming gusty Thursday afternoon and
evening.

.PREV DISCUSSION... /ISSUED 1009 PM CST Wed Jan 10 2018/

UPDATE...
Warm front stalled near the coast just south of GLS. Some light
fog north of the warm front around the GLS bay area but winds
appear to be helping to maintain the stratus deck. Guidance split
on where the warm front waffles to overnight. Higher res models
leave it in place along the coast and possibly even sagging
southward where as GFS is more aggressive moving it inland. For
now have favored the slower movement but this could make for a
bust at GLS with temperatures potentially rising the remainder of
the night.

On a further note cold front racing south through KS with
dryline/prefrontal trough in West TX slowly moving eastward. The
prefrontal trough should swing eastward through the area Thursday
afternoon with the cold front a 1-3 hours behind it. Very strong
winds are expected behind the front and will persist well into
Friday. Northerly winds of 20-30 mph with gusts 35 to 40 look
within reach and could even be stronger. Wind advisory a given and
combined with the winds the temperatures should make the wind
chill readings plummet into the 20-30 degree range 7 PM Thursday
through 8 AM.

00Z runs also continue to support the threat of thunderstorms
Thursday afternoon (CAPE 500-1100j/kg with LI of -2 to -5)
especially for the northeast and central areas with the erosion of
any lingering capping. Hodographs by that point though are
relatively linear so other than perhaps some small hail with the
stronger storms am not expecting any severe weather.
