Area Forecast Discussion
National Weather Service Houston/Galveston TX
1103 PM CST Fri Feb 9 2018

.DISCUSSION...
Current forecast looks on track. Development will continue over-
night as a series of shortwaves move across the region. Rainfall
totals so far have been light (generally right around a tenth of
an inch) but short-range models are keeping with more aggressive
shower/thunderstorm development overnight. Even with the contin-
ued lack of a discernible surface boundary, widespread rain with
locally heavier rains will remain possible...likely best at/near
the coast where moisture will be deepest. 41

.PREV DISCUSSION... /ISSUED 719 PM CST Fri Feb 9 2018/

AVIATION...
S/W moving through the coastal waters with extremely moist air
blanketing the area leading to overcast lower ceilings. Showers
becoming widespread and these should continue through the night.
As next s/w approaches expect lift to increase across the region
and between 05-11z will likely see heavy showers mixing in with
the low ceilings. Thunderstorms look more likely for the Houston
area terminals southward. As the subtropical jet noses after
12-15z expect another round of showers with main circulation
departing the CLL area by 16z...VCSH issues will continue into the
early afternoon for the southern sites.

GLS area will likely experience dense fog for a few hours before
the showers and thunderstorms stir it up this evening.

Low to very low ceilings will likely return after 18z for most
sites.
