Marine Weather and Tide Forecast for St. Hedwig, TX

SHORT TERM
(Tonight through Tuesday night)
Issued at 1200 PM CST Mon Dec 8 2025

Surface high pressure will lead to cooler temperatures for the start of the week, particularly over the northeastern portions of South Central Texas on Monday. After a much colder start to the day, afternoon temperatures should warm into the 60s for most, but some spots, primarily Burnet, Williamson, and Lee Counties will struggle to get out of the 50s today, despite full sunshine. High pressure will slide east tonight, but despite its departure, it will still be rather cool with strong radiational cooling expected Tuesday morning. Some locations will flirt with the freezing mark again, but most areas will likely dip into the mid to upper 30s. Tuesday will be warmer as southwesterly surface flow ramps up on the backside of the departing surface high with continued dry weather.

LONG TERM
(Wednesday through next Monday)
Issued at 1200 PM CST Mon Dec 8 2025

Much warmer temperatures are anticipated for mid to late week as WNW flow and weak mid-level ridging, along with very dry moisture within the column lead to highs in the mid to upper 70s across all of South Central Texas. By early Saturday, another cold front may work into the region, but model guidance is not confident on the timing or placement of this front at this time. In any matter, expect mild and dry weather through the entire forecast period.

AVIATION
(18Z TAFS)
