...New AVIATION...

.SHORT TERM...
(Tonight through Friday night)
Issued at 223 PM CDT Thu Apr 17 2025

Overhead mid-level ridging will shift east through the short term,
but the surface pressure gradient will remain tight between Gulf of
America based high pressure and upstream/inland lower pressure.
Consequently, enhanced winds will persist as the salient weather
feature in the short term. We expect winds to remain breezy
overnight and strengthen to windy again on Friday. Isolated coastal
showers appear in the NAM overnight, but confidence in their
development is low (<15%), so there is no mention of rain right now
in the official forecast grids. There is a good (60%) chance that we
will need a wind advisory on Friday as guidance suggests a slight
increase in winds over today. In a familiar pattern, winds should
relax to moderate to breezy Friday night. Temperatures will continue
to be above normal; upper 60s to mid 70s at night and mid 90s during
the day (except slightly higher for the Upper Valley and around 80
at the beaches).

The combination of depressed relative humidity values, enhanced 20
ft. winds, and drying fuels will increase the wildfire growth and
spread threat on Friday, meaning we may want to issue a fire danger
statement for portions of the CWA. Rip current risk will remain
high.

&&

.LONG TERM...
(Saturday through next Thursday)
Issued at 223 PM CDT Thu Apr 17 2025

Starting with Saturday, a low-level jet around 40 knots continues
appear over lower Texas coast starting in early part of Saturday.
The possibility of stronger winds and gust mixing down continues to
need to be monitored. If the winds and gusts are able to mix down,
then wind advisories are likely to be need along the coast. The
latest guidance does move this low-level jet off the coast by
Sunday.

An upper-level trough is still expected to move through the Central
Plains this weekend, which will push a cold front south through
Central Texas. The latest model guidance does show the front move
into the Northern Ranchlands late Sunday into early Monday. With the
latest model trend continuing to push the front a bit south each
run, rain chances may need to increase even further. Any additional
movement southward of the front will allow for a greater source of
lift and a better zone of moisture convergence. This in turn will
result in more showers and thunderstorms for Deep South Texas and
the Rio Grande Valley for Sunday and Monday.

As the front retreats from the region on Monday, upper-level zonal
flow is expected to return. However, a few shortwaves could move
through the region during the rest of the week resulting in some
atmospheric instability that will help produce some showers and
thunderstorms during the afternoon. However at this point chances
for rain each afternoon for the rest of the long term forecast
period are low (around 20%).

.AVIATION...
(06Z TAFS)
Issued at 1228 AM CDT Fri Apr 18 2025

MVFR to VFR conditions are expected to continue through the
period. MVFR ceilings at BRO are expected to continue until after
sunrise, with MVFR ceilings developing at HRL and MFE overnight.
Ceilings are expected to begin lifting later this morning, with
VFR ceilings expected this afternoon. Gusty southeasterly winds
are expected to continue through the period, with wind speeds and
gusts increasing around mid morning through the afternoon.

&&

.MARINE...
Issued at 223 PM CDT Thu Apr 17 2025

Tonight through Friday night...Winds and seas will remain elevated
through Friday due to the forcing from a tight pressure gradient,
with some improvement Friday night. We extended the small craft
advisory for all marine zones to Friday at 6 PM. Wave heights may
continue elevated after that, requiring another SCA extension but
winds will start to decrease.

Saturday through Next Thursday...While the early part of Saturday
will see mostly adverse conditions on the waters with winds just
under Small Craft Advisory, the winds and seas are expected become
further elevated during the day, due to the pressure gradient
tightening, resulting in hazardous conditions that will require
Small Craft Advisories. Winds and seas are expected decrease during
the day on Sunday leading to Small Craft Exercise Caution taking
over into early Monday. Light to moderate winds and moderate seas
are expected to return by Monday evening and last through the
remainder of the period.
