Area Forecast Discussion
National Weather Service Houston/Galveston TX
1150 PM CDT Sat Sep 23 2017


.AVIATION...
A few CU out there visible from the office at 04z over the Bay.
Winds overnight light/calm and favorable conditions for
patchy/areas of fog and so have kept with this in more rural TAFS
IFR/VLIFR conditions mainly after 09z. IAH/HOU should be mainly
MIFG or light fog conditions. Showers should begin to develop over
the coastal waters before sunrise and spread inland with scattered
showers and a few thunderstorms in the window between 19-23z.
These may be focused more into the Metro hubs...for now VCSH but
confidence increasing that VCTS will probably be needed at
HOU/IAH/CXO. Rinse and repeat again Sun night/Monday.

.PREV DISCUSSION... /ISSUED 953 PM CDT Sat Sep 23 2017/

DISCUSSION...
Current forecast looks good. Afternoon storms died off quickly
after sunset and skies have cleared across SE TX this evening.
Patchy fog still possible over inland areas overnight and into
early Sun morning given the clear skies/calm winds. Short-term
models keep with the idea of isolated/widely scattered showers
and thunderstorms tomorrow. 41

PREV DISCUSSION... /ISSUED 858 PM CDT Sat Sep 23 2017/

AVIATION...
Showers have ended and clouds dissipating. Expect VFR conditions
til around 06-09z with fog developing at many sites and VLIFR
possible toward morning. IAH/HOU should maintain VFR but could dip
into MVFR with MIFG/BR for a few hours near sunrise. Moisture
increasing slightly Sunday and with neutral/weak PVA at 500 and
easterly LL flow so expect an uptick in coverage. Will carry VCSH
after roughly 19z but will probably need to add in VCTS or a
PROB30 in upcoming package.

MARINE...
Minor tweaks to the winds based on current obs. Otherwise it looks
on track. Winds 5-10 or 10-15 knots for the most part with seas
2-3 feet.
