DISCUSSION

Issued at 124 AM CDT Sun May 10 2026

Warm and humid conditions will persist as southerly winds continue to advect moisture into the region ahead of an approaching upper- level trough and associated cold front. Sunday will be one of the warmest days of the period with afternoon highs expected to range in the upper 80s to upper 90s across the region. Thunderstorm chances will increase late Sunday as the front moves through South Texas. Latest guidance continues to show modest instability with sufficient mid-level lapse rates supporting a few strong to severe storms. Deep- layer shear remains somewhat marginal generally around 20-30 knots, which should limit storm organization somewhat. However, due to marginally unstable conditions, and considering PWATs near or above normal, SPC has placed much of South Texas under a Marginal Risk for severe thunderstorms with damaging winds and large hail as the main threats. Rainfall is expected to remain light to moderate with amounts generally under 1.0 inch, however isolated higher amounts remain possible with stronger storms.

The cold front is expected to clear the coast early Monday morning, ushering in a cooler and drier airmass across South Texas. Northerly winds will gradually weaken through the day as surface high pressure settles southward into the Southern Plains.

High temperatures Monday and Tuesday will likely remain in the low to middle 80s east and upper 80s west, with overnight lows dipping into the mid to upper 60s. With lower dewpoints dipping into the 50s and 60s behind the front, more comfortable conditions will result through at least mid-week. By Wednesday and Thursday, onshore flow redevelops as the surface high shifts eastward. Meanwhile, a Low over the Desert Southwest will reposition just lee of the Rockies but looks too weak and far north to send us another cold front but will keep a pulse on guidance trends and adjust the forecast as necessary.

AVIATION

(12Z TAFS) Issued at 542 AM CDT Sun May 10 2026

Patchy fog may develop this morning with light winds and abundant moisture over the Coastal Plains and Victoria Crossroads so have continued a mention of periods of IFR/LIFR conditions for ALI, CRP, and VCT. Conditions will return to VFR between 14Z and 16Z Sunday morning. MVFR conditions will return later tonight as a front approaches the area. Have introduced showers and thunderstorms for LRD, COT, and VCT late tonight into the early Monday morning hours.

MARINE

Issued at 124 AM CDT Sun May 10 2026

A light to gentle southeasterly breeze (BF 2-3) will persist through Sunday ahead of an approaching cold front. Winds and seas will increase slightly Sunday afternoon and evening, especially over the offshore waters. There's a moderate chance for showers and thunderstorms with frontal passage. A few storms may become strong to severe with locally higher winds and seas. Behind the front, winds will shift northeasterly Monday morning and briefly strengthen to moderate levels before diminishing Monday night. Weak to moderate onshore flow returns by midweek as high pressure shifts eastward.
