KEY MESSAGES

- Extreme Cold Warning through 9 AM CST due to temperatures. Icy roads linger in places, especially Hill Country to Austin area.

- Slow warming through Thursday, then turning colder Friday into the weekend.

SHORT TERM

(Today through Wednesday) Issued at 1203 AM CST Tue Jan 27 2026

An Arctic airmass remains across South Central Texas. Light winds, low dewpoints, and only thin cirrus makes for efficient radiational cooling. However, dewpoints have risen a little and should keep low temperatures higher. Will maintain the Extreme Cold Warning through 9 AM CST this morning due to lows in the mid teens to lower 20s. A warming trend begins Tuesday and continues Wednesday as the Arctic airmass erodes due to daytime mixing with warming mid level temperatures. Highs warm 5 to 10 degrees Tuesday and another 5 to 10 degrees Wednesday. However, a northerly flow off the snow/ice field just to our north may stall the warmup or even lower highs across our Central Texas and northeastern Hill Country areas a few degrees from Tuesday's. Another hard freeze is expected Tuesday night with lows in the 20s to near 30 due good radiational cooling. One thing to monitor is a possibility of late night/early morning freezing fog as the airmass moistens.

Record low temperatures are in jeopardy for Tuesday the 27th. See CLIMATE section below for details.

These conditions may cause hypothermia and frostbite if precautions are not taken. Keep people, pets, plants, and pipes warm, and practice safe use of space heaters. Icy spots will linger in places, especially Hill Country to the Austin area through Tuesday. Travel with extreme caution.

LONG TERM

(Wednesday night through Monday) Issued at 1203 AM CST Tue Jan 27 2026

Warming trend continues with lows within a few degrees either side of freezing Wednesday night and highs near average Thursday. A cold front moves across our area late Thursday afternoon into evening. Any precipitation with this system is now expected to be to our southeast. In wake of the frontal passage, a cooling trend begins Friday with hard freezes returning to most areas by the weekend. Cold weather highlights may be needed. Southerly flow returns on Sunday bringing a warming trend going into next week.

AVIATION

(12Z TAFS) Issued at 526 AM CST Tue Jan 27 2026

VFR flight conditions prevail. Mid to high level clouds move in and push west to east across the region, especially for the northern half, from later this morning through the afternoon before clearing tonight. We'll also monitor for the low chances for the development of any patchy freezing fog, mainly around sunrise both this morning and again Wednesday morning, where primarily any ice still remains on the ground. Impacts are not expected at the TAF sites but have elected to add a brief TEMPO group at KAUS for Wednesday morning with a few very low clouds around 100 feet, just in case it approaches the site. Light and variable winds are expected at night while the winds trend of around 5 to 8 kt during the day from the west-southwest for today and out of the west-northwest on Wednesday.
