Area Forecast Discussion
National Weather Service Houston/Galveston TX
1135 PM CDT Thu Mar 14 2019

.AVIATION...
VFR conditions anticipated through the TAF period across all
terminals tonight. Overcast ceilings between 7000-12000ft remain
across TAF sites along and south of I-10. Winds are out of the 
N/NW closer to 10 kts but should increase in speed over the next
few hours. Friday morning, gusty conditions (gusts around 20-30
knots) will be possible as the pressure gradient tightens across 
the region with sustained winds around 15-20 knots. These winds
will stay strong through late Friday afternoon. Model guidance 
such as the TT WRF, NAM12, and HRRR show the development of some
light rain across the coastal terminals Friday morning, spreading
inland during the afternoon hours. This better moisture will help
this overcast deck to spread further inland by Friday afternoon
across all terminals, but VFR conditions will still remain.

.PREV DISCUSSION... /ISSUED 940 PM CDT Thu Mar 14 2019/ 

DISCUSSION...
At 01z, a reinforcing cold front was just off the coast with a
1036 mb high over the Rockies ridging into Texas. The gradient
should tighten overnight and am expecting sustained winds to
increase. Will issue a Wind Advisory for the barrier islands
overnight into early Friday. Despite very dry air at the surface,
weak isentropic upglide, favorable jet dynamics and strong 
frontogenesis in the 850-700 mb layer will likely yield some light
rain along the coast by morning and this area of precip will 
expand slightly inland during the day. Not sure how far inland 
precip will go but the Canadian, NAM12 and NMM are more aggressive
with rain on Friday. Bumped PoPs up slightly and increased cloud 
cover a bit. 43
