DISCUSSION

Issued at 212 PM CDT Mon Apr 6 2026

After a soggier-than-normal Easter, much of South Texas has started seeing drier air usher into the region. Tonight, temperatures will drop into the upper 40s/low 50s with mostly clear skies (aside from streaks of cirrus). As surface high that has provided this early- Spring cool spell moves off to the Southeast, surface winds will shift more southeasterly, allowing Gulf moisture to creep back into the region. As such, the latter half of the week will see temperatures climb back to above-normal values with locations seeing rain having cooler temperatures.

Speaking of rainfall, while most of the rain that feel this Easter weekend was a welcome sight, it increased soil moisture than meaningful improvement to the surface water supply. This week's rain chances will be thanks to a shortwave moving moving through the state, bringing moisture into the upper-levels from the Pacific while at the surface, southeasterly flow will increase the surface moisture back into the region (PWAT values between 1.4" and 1.6" along the coastal plains). While there won't be significant surface boundary support, the confidence in scattered showers and thunderstorms is moderate for Thursday/Friday. We'll have a better idea of the convective nature of any precipitation during this time period when the CAMs start coming in (especially if we have thunderstorms developing over the higher terrain in northern Mexico associated with the dry line convective initiation and how far east any storm moves into the Rio Grande Plains).

Guidance with respect to tide levels have been tricky this week with high tide reaching 1.4-1.5 ft above MSL, which is generally below the level needed to cause beach flooding but with consistent high tides seeing water levels reach the dunes, the coastal flooding observed is likely being driven by the increased swell period. Latest guidance has the swell period increasing to 8-10 seconds through the weekend bringing continued chances for this hazard. While no products will be issued with this package, one may be needed for Tuesday's late morning high tide.

AVIATION

(18Z TAFS) Issued at 212 PM CDT Mon Apr 6 2026

VFR conditions will prevail through the TAF cycle. Main thing that will change will be the wind direction, from a NE heading to an E'ly heading late Tuesday morning.

MARINE

Issued at 212 PM CDT Mon Apr 6 2026

Winds will gradually veer to an easterly direction and become more gentle to moderate (BF 3-4) through Tuesday afternoon. From Tuesday night, winds will be more onshore with 2-4 ft seas. Rain chances will be low to moderate (20-40%) through Thursday before increasing to near 50% from Thursday night.

FIRE WEATHER

Issued at 212 PM CDT Mon Apr 6 2026

Although drier conditions will continue through Wednesday, slight rain and thunderstorm chances return to the forecast by late week into the weekend. Relative humidity values will remain above critical thresholds. Therefore, elevated fire weather conditions are not expected.
