National Weather Service Houston/Galveston TX
1133 PM CDT Sat Apr 29 2017

.AVIATION...
Cold front and associated line of shra, and a few embedded tsra along
the Highway 59 corridor should continue moving se at a pretty
good clip. Should be off the GLS coast by 2 am or so. Breezy NW
winds in its wake and ceilings going VFR. Continued breezy and
becoming sunny everywhere by mid to late morning Sunday. 47

.PREV DISCUSSION... /ISSUED 950 PM CDT Sat Apr 29 2017/
The rapid southeasterly advance of the cold front is certainly
doing a number on the (potential) convection this evening as it
undercuts the line. The boundary has passed across College Station
at the bottom of the 8 PM hour with 9 PM pressure rises and a
stout NW 20 mph wind gusting to over 30 mph. Will give it another
20 minutes or so and then...if activity doesn`t blossom up...will
be paring back/canceling the Severe Watch at 10 PM (an hour
early). Per a recent UH sounding...the downstream is pretty capped
between 7-850 mb so am not anticipating much more than the
passage of light showers between 10 and Midnight over metro...the
front should be clearing the coast between 8 to 9Z per recent 01Z
HRRR run. Breezy northwesterlies under early Sunday clearing
skies... becoming mainly clear by early afternoon. Afternoon
temperatures will slowly warm into the average middle 70s as lower
level cold advection continues through sunset. Surface high moves
over tomorrow night...weakens Sunday night/Monday morning
variable winds to near calm. Overnight resident dry air mass with
dew points in the 40s equates to Monday morning interior minTs in
the upper 40s to lower 50s...low to mid 60s along coast. 31
