National Weather Service Houston/Galveston TX
1139 PM CDT Wed Apr 17 2019
.AVIATION...
Mostly IFR ceilings across SE TX this morning with isolated
terminals at LIFR criteria. With the passage of the front,
anticipate more TAF sites to lower to LIFR criteria. Ceilings and
visibilities will improve starting mid to late morning hours as
the front pushes eastward. Most of the scattered light showers
have dissipated out ahead of tonight's cold front. Expect coverage
to increase as the main line of precipitation approaches. Biggest
change in this TAF package is with regards to the frontal timing.
Short term guidance has slowed the progression of this line by
an hour or two in the latest runs. As a result, have scaled back
the TAFs accordingly with the line of thunderstorms reaching CLL
around 08Z-10Z and eventually impacting GLS between 13-16Z. Strong
to severe storms with gusty winds (primary hazard) and hail will
be possible as the front passes through the region.
SE winds speeds have lowered but will become quiet gusty with
convection over the next few hours. W/NW winds will also be gusty behind
the front Thursday afternoon. Some wrap around clouds will be
possible mainly along and north of I-10 tomorrow afternoon. Some
of the short term guidance has also began to hint at some wrap
around precipitation during this time frame. Not confident enough
at this time to include in the 06Z TAF package.

.PREV DISCUSSION... /ISSUED 954 PM CDT Wed Apr 17 2019/
DISCUSSION...
At 9 PM, high pressure was located over the SE US and low
pressure was located over SW OK with a dry line extending south
from the low across the western TX. Some light showers continue
to stream into area from the Gulf but precip has remain widely
scattered and generally light. All that is about to change as a
line of storms approaches the region from the west. Between
06-09z, 300 mb winds split as an upper low over West Texas shifts
east and SE TX will lie in a well defined jet couplet. The PW
values surge to 1.90 inches over the western half of SE TX and
there is some weak surface convergence along what looks like a
weak outflow. On water vapor imagery there appears to be two short
waves lined up and the first of these will approach the region
around midnight and help maintain the convection over Central
Texas as it approaches SE TX. Instability parameters are
impressive with LI values near -10, CAPE values 2800 J/Kg and
Helicity around 220. SPC has expanded the Enhanced Risk a bit east
and this seems like the right call based on the instability and
the approaching the short wave.
SPC has also expanded the Slight Risk further east and this now
includes the Houston area. AMDAR soundings still show a strong
capping inversion in place at 700 mb and the million dollar
question is, will the cap hold or will it break. Short term
guidance has been trending a bit more aggressively with the HRRR
and TT WRF all showing convection approaching Houston around
sunrise as the second short wave approaches the region from the
southwest. Feel the combination of the short wave and strong upper
level diffluence will help to erode the cap and allow a second
area of storms to redevelop over the SW zones and move NE toward
Houston and points northeastward. Instability isn't quite as
impressive as points to our west but there could still be some strong
storms with gusty winds.
Speaking of winds, the actual front will mot reach the coast until
about 18z. The winds will become N-NW in the wake of the front and
will become strong. A Wind Advisory will likely be required for a
large part of SE TX Thursday afternoon. 43

The line of storms will approach the College Station area between 1 AM and 3 AM, the Houston area between 6 AM and 8 AM and the coast between 8 AM and 10 AM. The primary severe weather hazard is expected to be strong damaging winds and isolated tornadoes. A strong onshore flow will bring elevated tides to the coast and some minor wave run up could bring water over Highway 87 on the Bolivar peninsula Thursday morning. Strong northwest to north winds will develop in the wake of Thursday's cold front and a Wind Advisory may be required. .DAYS TWO THROUGH SEVEN...Thursday through Tuesday No hazardous weather is expected at this time. .SPOTTER INFORMATION STATEMENT...
