Synopsis for high island to the matagorda ship channel out 60 nm including galveston and matagorda bays
moderate to occasionally strong onshore winds are expected through early next week and seas will generally be between 3 and 6 feet. At times winds may be high enough during this period to require small craft exercise caution. Showers and storms are also possible at times through tomorrow night. Winds and waves would be higher in and near Thunderstorms.

New AVIATION

SHORT TERM
(Tonight through Friday night)
Issued at 254 PM CDT Thu May 2 2024

Key messages:

- Moderate risk of rip currents tonight

- Strong to severe thunderstorms possible over the Brush Country Friday afternoon

The GFS/ECMWF/NAM/Canadian deterministic NWP models predict the Victoria Crossroads under the LFQ of a subtropical jet streak late tonight/early Friday, and the ECMWF/Canadian place the western CWA under the RRQ of this jet streak by late Friday afternoon.
Slightly above normal PWAT values predicted for much of the period (deterministic GFS/NAM). The combination of the foregoing appear to drive the timing/position of mainly isolated convection during the period. Concur with the Marginal risk of severe for Friday over the Brush Country, when considering the NAM deterministic output of SBCAPE values 3000-4000 J/kg, and DCAPE magnitudes 1000-1500 J/kg late Friday afternoon/early evening for the central/western CWA The most recent spectral density and other output from the 42019 buoy suggest swell periods around 7 seconds, and the WaveWatch maintains this state overnight. Will retain the Moderate risk for rip currents tonight, yet an upgrade to a High risk may be needed if swell periods persistently reach 8 seconds.
Maximum Heat Index values may reach/exceed 105F over the Rio Grande Plains Friday afternoon.

LONG TERM
(Saturday through next Wednesday)
Issued at 254 PM CDT Thu May 2 2024

Key Messages:

- Increasing risk of heat related impacts next week.

Mostly dry conditions will persist through the long term period.
However there is a low (10-30%) chance for a thunderstorm to impact the Rio Grande Plains or northern Brush Country over the weekend.
Then it heats up as a more southwesterly subsident low level flow develops over the Sierra Madre spreading over South Texas. This will result in max air temperatures approaching 105 along the Rio Grande by Tuesday and a record 110 degrees by Thursday. Elsewhere temperatures will warm from the lower 90s on Tuesday to the mid- upper 90s by the end of the week. The risk of heat related illness will increase to moderate to high by mid-week, especially for vulnerable populations. While lower RH is expected out west to keep heat index values near the temps, farther east heat index values could exceed 110 degrees!

AVIATION
(06Z TAFS)
Issued at 1229 AM CDT Fri May 3 2024

MVFR/IFR ceilings will continue into the morning hours across the region. Ceilings will then improve to MVFR/VFR by the afternoon hours. There will be a low chance for isolated showers and thunderstorms across South Texas this afternoon and evening.
While the highest chance of convection will be across the western half of the CWA, confidence in impacts at either COT or LRD was too low to include a PROB30 with this forecast package. MVFR ceilings are once again expected to build into the entire region during tomorrow evening.

MARINE
Issued at 254 PM CDT Thu May 2 2024

Moderate onshore flow expected during the late afternoon and evening hours over the southern bays and southern nearshore coastal waters. Otherwise, generally weak to moderate onshore flow expected tonight through Friday night, in response to upper level disturbances upstream. A weak to moderate onshore flow will persist this weekend continuing through the upcoming work week.
