winds remain above caution thresholds this evening, and may flirt with advisory levels on Thursday. Shower and Thunderstorm chances begin to increase today and persist through the rest of the work week, mainly for the galveston bay area and its adjacent waters. Although the strongest storms are expected to remain inland, an isolated stronger storm or two cannot be fully ruled out.

SHORT TERM
(Current through Thursday night)
Issued at 353 PM CDT Wed May 1 2024

Southeast surface winds have promoted increasing moisture across the region with afternoon dew points observed in the low to mid 70s.
Convection has been slow to initialize this afternoon with only a few light radar returns across northern portions of the CWA Early afternoon CAM guidance continues to suggest scattered to possibly numerous showers and storms developing this afternoon into the evening. Of note, guidance has shifted activity more northward than morning model runs and greatest focus of initialization now resides along the north central CWA border, generally after 21Z. SPC Mesoanalysis tools continue to suggest a favorable environment for strong to severe storms with surface based CAPE values between 3,500- 4,000 J/kg and DCAPE values greater than 1,000 J/kg. However, the threat continues to remain conditional with models continuing to indicate a warm layer between 850-700mb. Of note, SPC has included a 2% probability of a tornado north of a line from La Salle to Aransas counties where effective layer STP values are greater than 2. In addition, strong to severe storms developing this evening will be capable of strong to damaging wind gusts and frequent cloud to ground lightning. There is a low risk of severe hail. Most convection is forecast to move north and west of the local CWA after 0Z with a few hints of a lingering storm across portions of Webb county into late evening.

Overnight, guidance has hinted at the potential for fog development across the coastal waters, advecting into the Coastal Plains. Any fog development is forecast to lift through sunrise. Into the afternoon, enough low level moisture remains in place on Thursday to support widely isolated showers and lightning storms during the afternoon (PoPs ~20%). High temperatures range the low to mid 90s across much of Brush country and the Rio Grande Plains. Temperatures mostly in the mid to upper 80s along the Coastal Plains and eastward.

LONG TERM
(Friday through next Tuesday)
Issued at 353 PM CDT Wed May 1 2024

A series of mid level shortwaves pass overhead through the period.
Model soundings indicate a dry mid layer generally persisting into early next week with limited moisture around 850mb. Mostly dry conditions are forecast through the period with any mention of precip limited to the Rio Grande Plains Friday and Saturday afternoon (PoP ~ 20%). Temperatures widely ranging the 90s across Brush country and the Rio Grande Plains late this week, warm to 100 degrees by Monday. Along the coastal plains and eastward, highs in the mid 80s to low 90s follow a gradual warming trend each afternoon.

AVIATION
(06Z TAFS)
Issued at 1025 PM CDT Wed May 1 2024

Storms have developed well north of the area this evening.
However, there is abundant moisture in place across S TX that could interact with the tail end of the upper disturbance that is moving across Central TX overnight. There is a very low chance for convection to impact VCT during the early morning hours.
Otherwise, MVFR conditions are expected across S TX overnight through Thursday morning. Brief VFR conditions are expected by early to mid afternoon across VCT, CRP, and ALI, then quickly becoming MVFR once again by early Thursday evening. MVFR conditions are forecast to persist across COT through much of the TAF period, while VFR conditions are expected across LRD by Thursday mid afternoon and then persisting through Thursday evening. Surface winds are progged to remain 5-15kt overnight before becoming gusty by mid to late Thursday morning into Thursday afternoon with gusts between 20-25kt.

MARINE
Issued at 353 PM CDT Wed May 1 2024

Small craft should exercise caution tonight for onshore winds of 15- 20 kts across the offshore waters. Onshore flow continues on Thursday, building seas to 4-6 ft. Seas gradually subside Thursday night through Friday as onshore flow falls to 8-12 kts.
