SHORT TERM

(Today through Tuesday) Issued at 1202 AM CST Mon Jan 26 2026

An Arctic airmass across South Central Texas gets a reinforcement on Monday as an upper level trough moves over the Central Plains. The Extreme Cold Warning remains in effect through Noon CST Monday due to a combination of wind chills and air temperatures. Lows in the teens with some single digits in the Hill Country and lower 20s along the Rio Grande are expected. Enough breeziness to the winds creates wind chills in the single digits most areas to as low as 5 degrees below zero in some Hill Country locations. In spite of ample sunshine, temperatures only manage to get a few degrees above freezing Monday afternoon. Surface high pressure settles across our area Monday night allowing for light winds, low dewpoints, and mostly clear skies to enable efficient radiational cooling with similar low temperatures to this morning. A Cold Weather Advisory may be needed for tonight into Tuesday morning as wind chills will be near air temperatures due to the above mentioned light winds. Surface high pressure moves to the east Tuesday allowing southerly winds to return, though highs only warm about 10 degrees from today's.

Record low temperatures will be broken Monday morning the 26th and are in jeopardy for Tuesday morning 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 is discouraged in those areas with extreme caution elsewhere.

LONG TERM

(Tuesday night through Sunday) Issued at 1202 AM CST Mon Jan 26 2026

Although temperatures warm Wednesday and Thursday, they remain well below average with hard freezes at night into early morning across most areas due to surges of surface high pressure. The scenario seen in previous models of a cold front and an upper level trough with a surface low briefly located off the Texas coast Thursday night through Friday that generates precipitation is becoming less likely. Models are consistent with a frontal passage while heavily trending toward a dry northerly flow surface and aloft. This is leading to decreasing precipitation chances. However, there remains enough uncertainty to keep them in the forecast for now. Well below average temperatures continue with hard freezes most areas next weekend.

AVIATION

(12Z TAFS) Issued at 522 AM CST Mon Jan 26 2026

VFR flight conditions continue under mostly to completely clear skies. Moderate north winds persist into this afternoon before subsiding to light and variable conditions this evening and tonight.
