DISCUSSION

Issued at 106 PM CST Sun Feb 22 2026

Fair and for some, comfortable weather continues today with plenty of sunshine, low humidity and afternoon temperatures ranging from the mid 50s to low 60s. Breezy north to northeast will continue this afternoon, though they are expected to weaken by sunset as the pressure gradient decreases and with the loss of daytime heating. It is very dry out there, with surface dewpoints in the 20F to 30F range, bringing relative humidity down to between 20% to 30%. Because dry conditions and breezy winds are a poor combination for fire safety; please, use caution with fire this afternoon.

Be prepared for a chilly night. Dry northerly winds and mostly clear skies will result in cold conditions tonight. Overnight lows will drop into the 30s across most areas. Near or below-freezing temperatures are possible across portions of the Brazos Valley, particularly in Houston and Madison Counties. The Houston metro area and the islands will remain in the 40s.

With high pressure dominating across the Plains, and persistent CAA, a cool start to the workweek is expected. Highs on Monday will generally range in the mid 60s with low humidity and light to occasionally moderate north to northeast winds.

The main weather story for the rest of the week is a trend toward warmer conditions. Ridging aloft breaks down after Tuesday, bringing back southerly surface flow across the area. Highs will generally reach the 70s. Conditions will turn even warmer after midweek as a warm front lifts across the area and winds shift slightly to a more southwesterly component. This will result in highs reaching the 80s Wednesday and Thursday.

A cold front will attempt to move across SE TX on Thursday; however, no significant impacts are expected other than temperatures dropping a few degrees by Friday. In terms of precipitation, the only window for rain will be with the FROPA. However, most of the forcing looks to remain to our northeast/east. Will continue with precipitation chances as NBM suggests with only a slight chances over the Gulf on Thursday.

AVIATION

(12Z TAF Issuance) Issued at 528 AM CST Sun Feb 22 2026

Outside of a few scraps of 250 cirrus, SKC throughout. The only real forecast issue is timing for gusty north winds gradually diminishing late this afternoon/early this evening.

There is one related safety note though, primarily for awareness of GA pilots. While the stronger surface winds largely preclude the need for explicitly including LLWS in the TAFs, there may be transient stretches if/when those winds go into a relative lull where there could be some noticeable low level wind shear. For more information, see the AIRMET in effect for the region this morning.

MARINE

Issued at 106 PM CST Sun Feb 22 2026

Moderate to strong winds continue, though they will remain below Gale Warning criteria. North winds around 15 to 25 knots with higher gusts and elevated seas are expected through late tonight. Small Craft Advisories are in effect until early evening for the bays and until early Monday for Gulf waters. While conditions will remain below advisory levels, strong offshore winds will also lead to low water levels over the bays, especially during low tides through Monday. Onshore winds return by Tuesday as the high pressure shifts to our east. Winds may become moderate to strong at times through the rest of the workweek.
