Synopsis for the middle texas coastal waters -
moderate to strong onshore flow will persist this afternoon into Friday, as an upper level disturbance approaches the southwestern united states. A persistent strong onshore can be expected through Sunday when small craft advisory conditions are likely. Winds become weak to moderate during the day Monday and will persist through the remainder of the period. Isolated showers and Thunderstorms will be possible daily Sunday through Tuesday as a couple weak disturbances move over the area.

SHORT TERM
(Tonight through Friday night)
Issued at 355 PM CDT Thu Apr 25 2024

Key Messages:

- High risk of rip currents this afternoon through Friday

- Wind Advisory conditions possible Friday

- Isolated thunderstorms possible over the northern Coastal Plains and Victoria Crossroads Friday

There were minor changes made to the forecast. Due to obs reporting higher winds, seas reporting heights around 4 feet and 7 second periods per Buoy 42019 around , along with the influence of the full moon the rip current risk was elevated to a High risk for the rest of today through tomorrow. Erring on the side of caution due to the fact wave heights are expected to increase overnight tonight and winds are expected to persist through tomorrow.

With the presence of increased onshore flow due to the upper level disturbance moving across the southwestern US and a tightening pressure gradient, Wind Advisory conditions will be possible tomorrow. Models have been on a down trend from previous runs with the 13Z run of the NBM ensemble showing lower probabilities. They do however predict wind gusts to still be borderline Wind Advisory criteria, therefore it's not completely out of the question. This will be reassessed later tonight in order to get a better gauge on the threat. Some energy associated with the upper level disturbance will move through the area and combine with above normal PWATS (1.7- 1.9 inches) which could allow for some isolated thunderstorms over the northern Coastal Plains and Victoria Crossroads Friday. The caveat to this will be higher CIN values which should limit chances.

Conditions will remain humid tonight with lows in the 70s expected.
High temperatures to the east will be in the mid 80s with mid 90s out west due to less cloud cover.



LONG TERM
(Saturday through next Wednesday)
Issued at 355 PM CDT Thu Apr 25 2024

- Medium to high chance of Wind Advisory conditions for portions of South Texas Saturday

- Very warm Saturday with highs near 100 degrees out west

- Low to medium rain/storm chances daily Sunday through Thursday

Latest medium range models still indicate a strong surface pressure gradient setting up over the area Saturday into Saturday night leading to a medium to high chance of Wind Advisory conditions. This is in response to a deep layer trough advancing from the Rockies into the Central Plains. As this trough lifts into the upper midwest on Sunday, a weak boundary will stall over Central Texas causing our pressure gradient to relax. There remains a low to medium (20-50%)
chance for showers/thunderstorm across our northern CWA on Sunday due to convergence along the boundary and lift associated with the tail end of the upper trough.

A nearly zonal flow aloft will bring a steady stream of s/w's over South Texas through the work week. This will combine with a persistent onshore flow and abundant moisture with PWATs in the 1.5 to 1.9 inch range (99th percentile) to bring daily low end chances for showers and thunderstorms. The main inhibitor is the lack of low level focus. The operational 06z ECMWF is currently an outlier with regards to a slightly deeper trough forming over the eastern CONUS Wed-Thu, bringing a boundary into the region and a potential for a large MCS to sweep through the area. The 12z ECMWF still brings an MCS into the area but is less amplified with upper trough. The rest of the guidance including the EPS, GEFS and GEPS ensemble forecasts maintain a more zonal flow. Will carry low chances for PoPs at this time and continue to monitor.

Temperatures will be very warm on Saturday as a dryline nears the area from the west. Highs are forecast to approach the upper 90s to around 100 degrees over portions of the Brush Country and Rio Grande Plains, with maximums in the mid 80s across the east. Otherwise, expect highs to range from the low 80s to mid 90s through the end of the work week, with overnight lows generally in the upper 60s to mid 70s.



AVIATION
(18Z TAFS)
Issued at 1250 PM CDT Thu Apr 25 2024

Ceilings will improve across the western terminals (ALI,LRD,COT) from MVFR to VFR. MVFR conditions will persist across the remainder of the area through this evening. Winds are expected to remain elevated around 15-20 knots with gusts up to 30 knots possible through the end of the forecast period (Midday Friday). This evening ceilings will transition to MVFR with periods of IFR expected at sites (VCT and CRP). Ceilings will remain MVFR through the remainder of the period with some clearing out west (COT and LRD).
