New SHORT TERM, LONG TERM

SHORT TERM
(Tonight through Thursday night)
Issued at 120 PM CDT Wed Apr 24 2024

Mid/upper level ridge over South Texas this afternoon will shift to East Texas on Thursday as next trough advances into the central Rockies. This will result in the development of a surface low in the Lee of the Rockies and gradual strengthening low level flow across the southern plains into South Texas through Thursday afternoon. Given the strengthening moist southerly flow and strong low level capping inversion, expect a stratus cloud deck to redevelop over the forecast area tonight with clouds lingering most of Thursday, with the exception of the west where some clearing is expected. Winds will gust around 25-35 mph on Thursday but are not expected to reach wind advisory levels. Small Craft Advisory conditions are expected over the southern bays on Thursday expanding to the gulf waters Thursday Night. A s/w will track to the north of our forecast area Thursday night with a less than 10% chance for convection developing across the northwest brush country. Given the subsident flow aloft, continued warming will occur out west on Thursday with max temps in the mid 90s and heat indices reaching the triple digits. Elsewhere mid 80s are expected.

LONG TERM
(Friday through next Tuesday)
Issued at 120 PM CDT Wed Apr 24 2024

Key Messages:

-Medium to high chance for Wind Advisory Conditions for portions of the Coastal Plains and Victoria Crossroads Friday and Saturday

-Very warm conditions Saturday with highs around 100 degrees out west

The forecast looks to remain on track from the previous issuance. A series of upper level short waves will move across the area. This will be in conjunction with above normal PWAT values (1.7-1.9 inches). This will allow for isolated to scattered showers and thunderstorms mainly along the northern portions of the CWA and Victoria Crossroads Friday, Sunday, Monday, and Tuesday. Models (GFS/ECMWF) depict a surface low developing out west on Friday and lingering through Saturday. This will enhance the tightening of the pressure gradient over the Coastal Plains and Victoria Crossroads which will cause some periods of Wind Advisory Conditions.
Conditions over the waters will be SCEC to SCA in response to the elevated winds Friday through Monday.

Expect hot weather through the long term with highs expected to be in the 80s and 90s each day with 100s out west Saturday. It appears that summer made an early appearance this year with all of the heat that we have been experiencing.

AVIATION
(18Z TAFS)
Issued at 1202 PM CDT Wed Apr 24 2024

Expect mostly cloudy skies with MVFR ceilings becoming VFR in the next few hours as mixing continues. Southeast winds could gust around 20 knots at times through early evening. Low MVFR ceilings will redevelop along the coast this evening becoming IFR near the VCT Terminal late. Clouds will persist through midday Thursday before gradually lifting. Expect winds to be stronger on Thursday gusting in 25-30 knot range by afternoon as the pressure gradient tightens in response to low pressure in the Rockies.
