KEY MESSAGES

- Dangerously cold temperatures will continue this morning before temperatures rise above freezing by this afternoon. - Additional dangerous cold is possible later this week.

DISCUSSION

Issued at 309 AM CST Tue Jan 27 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 today (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/

The previous discussion remains valid. Additional cold weather graphics were not generated this forecast cycle for the late-week reinforcing cold to avoid confusing messaging possible until after we get past this morning's cold. We will experience a brief "warm up" through mid week with highs finally rising above freezing across the area by afternoon today. It's likely that cold weather messaging will be required for the late week reinforcing cold and that could begin as early as later today or tonight. Winter carries on through the extended period with temperatures at or below climate normals for the foreseeable future. Much to my dismay, winter continues. /86/
