KEY MESSAGES

- Protect the 4 P's of Cold Weather: People, Pets, Plants, and Pipes thanks to another cold night with lows in the low to mid 20s across most locations

- Milder weather returns during next week with low (15-25%) rain chances midweek across the Coastal Plains

SHORT TERM

(Tonight through Sunday night) Issued at 1151 AM CST Sat Jan 31 2026

Surface high pressure builds southward this afternoon behind a secondary boundary that moved through the region overnight. While there will be plenty of sunshine today, it will be a chilly day with highs ranging from the low to mid 40s for our northeastern counties to the mid 50s along the Rio Grande. Moderate to breezy north to northeasterly winds maintain into the afternoon with gusts around 25 mph. Speeds then subside later this afternoon into tonight with the surface high becoming centered to our east- northeast. Clear skies and lighter winds should yield to radiational cooling and colder air temperatures tonight. Most will dip into the low to mid 20s except for locations along the Rio Grande, which should trend closer to 30 degrees. With light winds, expect for the wind chills to remain near the air temperatures. As a result, the region generally remains above the criteria for the issuance of a cold weather advisory tonight. Regardless, continue to promote and practice cold weather safety by protecting the 4 P's of cold weather: People, Pets, Plants, and Pipes

A warming trend starts Sunday into Sunday night as the surface high slides east and a light south to southwesterly surface wind develops across the region. The mid-level flow aloft should encounter changes as well with a shortwave ridge initially moving across the region during Sunday followed by a shift to more of a west-southwesterly flow from Sunday night into Monday. This west- southwesterly flow aloft should also help to usher in some increasing high clouds from the overnight into Monday morning. Highs on Sunday reach the mid 50s to near 60 degrees for most while Sunday night will see lows in the 30s.

LONG TERM

(Monday through next Saturday) Issued at 1151 AM CST Sat Jan 31 2026

A warming trend maintains into early next week with the southerly low-level flow and with a tame weather pattern aloft. The southerly flow helps to advect higher low-level moisture into the region and this will yield to the return of increased cloud cover, especially at night and into each morning. A modest cold front arrives towards the latter half of the day on Tuesday with the help from a shortwave pushing southward through the Central Plains that will likely then pivot more southeastward towards Louisiana. The front helps to provide the low end (15-25%) chance for rain across our coastal plain counties from Tuesday afternoon into Tuesday night but most locations will not receive any rain. The front does bring drier air and a slight cool down in it's wake but not much in comparison to the stronger fronts that could occur this time of year. Temperatures look to warm late week as the mid- level ridging across the western CONUS builds more east and as the low-level flow turns back to the west-southwest. Besides the small rain chances along the front midweek across the Coastal Plains, no rain is expected.
