Area Forecast Discussion
National Weather Service Houston/Galveston TX
1149 PM CDT Thu Apr 18 2019

.AVIATION...
GOES-16 night time satellite imagery shows high clouds pushing
southeastward tonight and should pass across the region, and
possibly produce a light shower or two at UTS in the hour or two.
Not confident enough at this time to mention any rain in the TAF,
as no observations upstream are actually showing anything reaching
the ground. VFR ceilings still expected to prevail through the 
TAF period. Northwest winds less than 10 knots expected overnight.
Shortly after sunrise, wind speeds will pick up once more with 
sustained northwesterly winds between 15-25 knots with gusts 
between 20 to around 30 knots possible. Winds will slacken by 
tomorrow evening, just outside of the current TAF period, as high 
pressure builds back into SE TX.

.PREV DISCUSSION... /ISSUED 942 PM CDT Thu Apr 18 2019/ 

DISCUSSION...
A cold front has crossed the area and considerably drier air
has worked into the region and dew pts have fallen into the upper
40s NW of a Columbus to Crockett line. Dry air will continue to
push SE and the combination of clear skies and dry air should
allow temps to fall overnight. Some mixing provide by modest winds
should mitigate a free fall in temps but low/mid 50's seems
reasonable. 

Winds pick up again on Friday and coastal regions may require a 
Wind Advisory. Winds will drop off Friday night as surface high
pressure drifts over the region. The upcoming weekend looks great
with abundant sunshine. Temps will warm on Sunday and humidity 
levels will also increase as onshore winds increase but as spring
weekends go, its about as close to perfect as you get. 

Made some minor changes to hourly grids but the previous forecast
is on track and no major changes planned. 43
