KEY MESSAGES

- Dangerously cold temperatures will continue as many locations have remained below freezing today and will fall into the teens again tonight.

MESOSCALE UPDATE

Issued at 638 PM CST Mon Jan 26 2026

Rest of tonight...

Dangerous cold has settled in across the region. Evening surface analysis indicates 1038-1039mb surface high has settled across the ArkLaTex into south TX and will sink south and east overnight. The Gulf Coast remains under strong subsident portion of the upper jet and combined with arctic surface high drifting over and winds decoupling and near calm, clear and favorable radiational cooling is on tap. This is extremely dangerous for areas with extensive power outages and residual snow and ice cover, which will amplify the longwave radiation potential. Based on that, blended towards 25th percentile of NBM on lows due to snow and ice cover and amplified radiational cooling potential. A large portion of the area northwest of the Interstate 59 corridor did not reach freezing, potential for ruptured water pipes remain possible. Please ensure pets and friends and relatives have a warm place to stay. Follow all safety instructions for portable generators and heaters. Updates are out. /DC/

DISCUSSION

Issued at 1213 PM CST Mon Jan 26 2026

Dangerously cold temperatures will still be the main concern through this next weekend. While "product criteria" for Cold Weather Advisories or Extreme Cold Warnings will end tomorrow (warming wind chills), the extensive power outages will compound risks from cold exposure. This is especially the case in vulnerable populations and where structures are not well insulated. As we back down from currently advertised "Significant" to "Extreme" dangerous cold messaging on the back side of this event, we will likely advertise some degree of messaging on local graphics and products through the end of this week. Another strong system diving from Canada late in the week will bring another bout of very cold air, and likely push overnight lows into the teens Friday night with wind chills of 5 below zero to 5 above. This would require another round of Extreme Cold Warning products across the region. No significant accumulations of wintry precipitation are expected, but can't rule out some light precip in parts of the region as a disturbance moves south of our area Friday or Saturday. /NF/

AVIATION

(00Z TAFS) Issued at 638 PM CST Mon Jan 26 2026

Earlier clouds has mostly dissipated with variable winds turning out of the southwest by 27/15Z Tuesday. Some additional low stratus cannot be ruled out Tuesday from melting ice/sleet. /DC/NF/
