New AVIATION

SHORT TERM
(Tonight through Sunday night)
Issued at 253 PM CDT Sat Jul 20 2024

Key Messages:

- Shower/thunderstorm chances low to medium across South Texas, high over the waters

Rest of Today and Tonight

An upper air trough over the region combined with minimum PVA at 500mb and precipitable water (PWAT) values up around 2.15 inches along the coast and lower inland will lead to a low to medium chance (20-35%) for showers/thunderstorms today. Activity today will be focused along the seabreeze and over the waters. Extending further inland as the sea breeze moves east to west across the region. The loss of daytime heating during the overnight hours will result in decreased precipitation, with mainly dry conditions.

Sunday and Sunday Night

Looking ahead to tomorrow, we anticipate an increase in low-level flow along with the approach of a weak tropical wave. This will further increase moisture levels, pushing PWAT values up to around 2.25 inches. The combination of increased moisture and PVA from 850- 500mb will lead to higher rain chances, particularly over the Gulf Waters (with a medium to high chance 40-75%) where moisture and mid- level lift support are strongest, while the Coastal Bend and the Coastal Plains will see low to medium rain chances, ranging from 20- 50%.

Temperatures and Heat Index

Temperatures will remain in the 90s across South Texas. Combined with dewpoints in the mid to upper 70s, heat index values are expected to range from 105-109 degrees. This will continue to pose a minor to moderate risk of heat-related impacts for the region.

LONG TERM
(Monday through next Friday)
Issued at 253 PM CDT Sat Jul 20 2024

Key Messages:

- Increasing moisture will lead to higher rain chances next week.

- Marginal Risk of excessive rainfall and flash flooding Monday.

- Slight Risk of excessive rainfall and flash flooding Tuesday and Wednesday.

Only minor changes to the inherited Extended forecast package were required today, mainly just adjusted the QPF values based on the latest forecast from WPC.

A trough extending from the Great Lakes region southwestward into South Texas will combine with plentiful moisture and several mid- level disturbances to lead to unsettled weather conditions across the region through the end of forecast cycle. PWATs are progged to steadily increase over the area through mid week, going from around 2" on Monday to near 2.3-2.5" by Wednesday, which is closer to the 99th percentile for this time of year. The passing of the several weak shortwaves aloft, the presence of a moderately unstable atmosphere (SBCAPE values ~1000-2000 J/kg) and some weakening of the cap will provide daily chances for showers and thunderstorms through the end of the work week.

The highest precip and convective chances can be expected Tuesday to Thursday period, when PoPs increase to around a 60-90%. Latest guidance from WPC indicates total rainfall accumulation of 2-4" through Friday, with the highest amounts forecast over northern and eastern portions of the CWA mainly on Wednesday. The risk of excessive rain goes from Marginal (level 1 out of 4) over northern zones on Monday to a mixture of Marginal and Slight (level 2 out of 4) risks areawide on Tuesday, into a widespread Slight risk by Wednesday. This indicates there is at least a 5-15% chance of rainfall exceeding flash flood guidance during the aforementioned period. Certainly something to pay close attention to as we continue to fine tune the forecast over the coming days.

Aside from the convective and flash flooding potential, no other hazards are anticipated across South Texas through late in the week.
Though, models are beginning to indicate the upper pattern to change with the development of a low either over north central Mexico or over the state next weekend. But, that is beyond the scope of this forecast package. Temperatures will remain at near normal levels through the end of the week mainly due to the increased cloud coverage and rainfall probabilities.

AVIATION
(06Z TAFS)
Issued at 1034 PM CDT Sat Jul 20 2024

Generally VFR conditions will prevail through the TAF period.
Brief MVFR visibility will be possible for ALI and VCT, so a TEMPO is included from 09Z to 13Z.

MARINE
Issued at 253 PM CDT Sat Jul 20 2024

Weak onshore flow this afternoon will persist through the weekend.
Low chance for showers and thunderstorms tonight, will ramp up to a 40-75 percent chance Sunday. Weak to occasionally moderate south to southeasterly flow will persist through next week. Low to medium rain chances of 20 to 50 percent early Monday morning will increase to medium to high chances of 60 to 90 percent heading into middle of next week.
