KEY MESSAGES

- Elevated fire wx conditions due to low humidity and light winds. - A warming trend is expected after Tuesday with highs generally in the 80s.

DISCUSSION

Issued at 1213 AM CST Mon Feb 23 2026

Another day of cool dry weather is in store as surface high pressure moves through SE Texas today. Highs are still expected to reach the 60s during the daytime, dropping overnight to the 30s/upper 40s early Tuesday morning. Afternoon RH should be slightly drier today as well, around 15-25% for most inland areas and near 30% along the coast. Surface winds will generally be north to northeasterly around 10 mph or less with some higher gusts. As a result, most areas should experience elevated fire weather conditions today. Caution should be exercised when working with open flames or operating equipment that can cause sparks.

High pressure slides off to the east on Tuesday, thus onshore flow returns and ushers in a warming trend through mid week. Tuesdays highs should climb to the upper 60s/lower 70s with overnight lows in the upper 50s/lower 60s. We'll also see some breezy weather settle in too as the gradient tightens from a deepening low near the TX/OK panhandle. Temperatures for Wednesday should see a significant bump with highs reaching the 70s/lower 80s across the area with lows overnight generally in the 60s.

Thursday should be pretty warm during the daytime with highs pushing the mid 80s in some spots. However, a cold front is anticipated to push through SE Texas in the evening, briefly cooling down the region with lows for Friday morning dropping to the upper 40s/50s. Highs on Friday will be slightly cooler, though the day itself will still be pretty warm with afternoon highs climbing to the 70s. Onshore flow returns Friday night, allowing the warming trend to resume heading into the weekend.

Elevated winds and seas continue early today, generally around 15-20 knots gusting up to 25 knots with wave heights around 3 to 6 feet. Observations show sustained winds hovering near that 20 knot mark, thus decided to maintain current Small Craft Advisory through early today to allow for more substantial improvements in conditions. Negative water levels are anticipated in the bays, reaching around -0.5 ft MLLW at low tide. Onshore flow returns and strengthens on Tuesday. Caution flags and additional Small Craft Advisories may be needed Tuesday night through early Thursday leading up to another cold front.
