Synopsis for the middle texas coastal waters -
weak east-northeast flow is expected today along with a low to medium chance for showers and Thunderstorms over the bays and nearshore waters. A few storms could be strong to severe. Rain chances decrease Friday night. Drier conditions expected Saturday and Sunday, as an upper level disturbance moves east.

SHORT TERM
(Today through Saturday)
Issued at 337 AM CDT Fri May 17 2024

- Marginal Risk (level 1 out of 5) for severe thunderstorms across the southeastern portion of our CWA today.

Rain chances are set to continue today. An outflow boundary originating from an earlier MCS in the Hill Country has moved through South Texas. This boundary intersected an embedded shortwave tracking across the region ahead of an approaching upper-level trough. The atmospheric environment is highly unstable, characterized by ample moisture, with the 00Z CRP sounding indicating over 6000 J/kg of SBCAPE and model PWAT values are ranging from 1.5 - 2.0 inches. However, a strong capping inversion is also present, which may initially inhibit convection.

CAM guidance suggests that convection will begin to develop across Mexico just southwest of our CWA between 08 - 12Z, moving northeastward as the embedded shortwave advances. Additionally, the main trough nearing the region will enhance upper-level diffluence, aided by a 105 - 110 kt upper jet sinking southward. Given these dynamics, there is a low to medium (20 - 50%) probability of shower and thunderstorm development.

This activity could become strong to severe, particularly across the southeastern portions of out CWA where favorable instability and moisture coexist with mid-level lapse rates around 7 - 7.5 C/km and 0 - 6 km bulk shear around 60 - 80 kts. The primary hazards from these storms will be large hail and damaging winds. SPC has placed the southeastern CWA under a Marginal Risk (level 1 out of 5) for severe weather, while the rest of South Texas is in a general thunderstorm risk. The optimal timing for severe weather appears to be from this morning into the afternoon hours, with all activity expected to dissipate and move out of the area by late evening. As this upper-level disturbance moves east, ridging will build in behind, allowing for dominant quasi zonal flow and the return of warm and dry conditions for the weekend.

LONG TERM
(Saturday night through next Thursday)
Issued at 337 AM CDT Fri May 17 2024

Key Messages:

- A risk of heat related impacts Monday through Thursday across the Brush Country and southern Coastal Plains.

A warmer airmass is predicted to develop over the region Monday through Thursday, manifested by an upper ridge that builds over the region, per the GFS/ECMWF. A progressive pattern is expected to remain over the northern approximately 3/4 of the CONUS, with upper disturbances moving close yet remaining north of the CWA
Nevertheless, these disturbances will continue to return flow and increasing moisture over the region beginning Sunday. The GFS/ECMWF predict PWAT values to increase above normal over the CWA Monday and continue through the remainder of the period. The combination of heating and greater near surface moisture will increase maximum Heat Index values over the CWA WPC continues to predict a 40-70 percent chance that the maximum Heat Index threshold of 110F will be met over the Brush Country and southern Coastal Plains Monday through Thursday. The NBM continues to predict 8s maximum swell period over the coastal waters Saturday/Sunday, which would increase the risk of rip currents along the Gulf-facing beaches to the Moderate category.

AVIATION
(06Z TAFS)
Issued at 1047 PM CDT Thu May 16 2024

A boundary surging south across the area has resulted in northerly winds gusting to around 25 knots. Thoughts are that these strong winds will diminish shortly before the beginning of the 06Z TAF cycle, but it is possible a few locations could see these lingering for a few hours. Otherwise, light winds are generally expected through the TAF period. Ceilings will bounce between MVFR and VFR overnight before eventually settling on MVFR by morning.
Sites over the Coastal Plains and Victoria Crossroads may experience brief IFR conditions so have included a TEMPO for this.
There is a low to moderate chance for showers and thunderstorms to develop late tonight and into midday Friday. A few of these could be strong to severe, with large hail and damaging winds as the primary threats. Ceilings and visibility could be reduced in and around any thunderstorms. Haze is expected to persist across South Texas, but ceilings and visibility should become VFR by Friday evening.

MARINE
Issued at 337 AM CDT Fri May 17 2024

Weak east-northeast flow is expected today along with a low to medium chance for showers and thunderstorms over the bays and nearshore waters. A few storms could be strong to severe. Rain chances decrease Friday night, followed by drier conditions through the weekend. Warm conditions are expected Monday through Thursday, with weak to moderate onshore flow. Maximum Heat Index values 90-95F Tuesday through Thursday.
