New AVIATION

SHORT TERM
(Tonight through Wednesday night)
Issued at 314 PM CDT Tue Apr 30 2024

Key Messages:

▶ Coastal Flooding and High Risk of Rip Currents will continue into tomorrow

▶ Low to medium chances for showers and thunderstorms

Quasi-zonal flow is expected to continue tonight through Wednesday night which should lead to generally quiet weather. A shortwave is expected to traverse across the region tonight and tomorrow, with the one tomorrow being the more significant one leading to our best chances for rain. The shortwave tonight is expected to be north of our CWA, however, some Hi-res models are showing the tail end of the vorticity sneaking into the Rio Grande Plains with a low chance to promote some thunderstorms. The shortwave tomorrow is expected to be a little bit stronger which when combined with an abundance of available moisture, will lead to low to medium chances for rain.
Some Hi-res models are showing an MCS develop in the Hill Country tomorrow and sweeping into South Texas, however, confidence on that solution remains low at this time.

Despite swell heights and periods finally beginning to decrease, they remain elevated as Buoy 42019 showing swell heights of 4.5-5 ft and periods of 8-9 seconds. With swell heights and periods remaining elevated and webcam across local beaches today continuing to show minor coastal flooding, did not feel comfortable letting the advisory expire tonight. These conditions will also lead to a continued risk of high rip currents. This will be especially noticeable in any areas of egress from the intracoastal waters as the waters from minor coastal flooding find their way back to the Gulf.

Warm temperatures are expected to continue tomorrow with highs in the mid 80s to mid 90s with heat index values from the mid 90s to near 102 degrees. Overnight lows will not provide much relief as

LONG TERM
(Thursday through next Monday)
Issued at 314 PM CDT Tue Apr 30 2024

Key Messages:

▶ Low chance (10-30%) of showers and thunderstorms through Saturday

▶ Minor to moderate risk of heat-related impacts daily

Predominantly zonal flow will persist across Texas into the upcoming weekend with shortwave disturbances combining with above normal moisture (PWATs 1.6 to 1.9") to bring daily low end chances for showers and thunderstorms. The limiting factor will be the lack of a surface boundary. However the sea breeze may provide that focus as it propagates inland from the coast during the peak of the afternoon/evening. Best chances for a shower or thunderstorm will be across the Rio Grande, Brush Country and northern coastal plains.
ECENS continues to be the wetter solution with Total QPF greater than 1", while the GEFS is indicating about 1/3 of that amount.
Conditions dry out for Sunday as a weak mid level ridge moves overhead.

Otherwise, heat will continue to be our primary concern through the extended forecast with high temperatures in the upper 80s to upper 90s and lows only dropping into the 70s. Max heat indices could approach 105 out west late in the week. Please remember to drink plenty of water and take frequent breaks if outdoors for a prolonged period of time. Additional heat safety can be found at: weather.gov/safety/heat

Coastal Hazards
moderate onshore winds and wave periods of 7- 8 seconds Thursday/Friday may lead to a continuation of minor coastal flooding and increased risk of rip currents.

AVIATION
(00Z TAFS)
Issued at 618 PM CDT Tue Apr 30 2024

A mix of VFR/MVFR this evening, will become predominately MVFR across S TX by 03-05Z. Conditions are expected to improve to VFR Wednesday afternoon except VCT and ALI where MVFR CIGs may persist. Showers and thunderstorms developing across Mexico this afternoon may move toward COT and LRD through the evening, but are forecast to diminish as they approach the Rio Grande Plains.
Included a TEMPO group for COT/LRD to address a few showers making into the area this evening. There is a chance of showers and thunderstorms Wednesday, but should generally stay mainly across the northern Brush Country to the Victoria Crossroads.

MARINE
