DISCUSSION

Issued at 1228 PM EST Mon Jan 26 2026

We start the period in the deep freeze, and the main story of this week can be summed up in one word. Cold.

Temperatures this afternoon will stay below freezing, and tonight temperatures will drop into the single digits over nearly all of our area. There are still some scattered light snow showers and flurries being squeezed out as is typical in these arctic air masses, but these will gradually diminish this afternoon and evening. The winds will become lighter overnight as the temperatures drop, but the combination of the low temperatures and the wind that is still around will bring wind chill values down into the 5 below zero to 5 above across much of the valley at times, and zero to 15 below zero at times in the mountains of E TN and SW VA. Will keep the cold weather advisories that are in place for tonight and Tuesday morning.

We will remain under a deep eastern CONUS upper trough with generally northwest flow aloft and cold air persisting over the area for the entire week and through the weekend. There will be a few moisture starved short waves that rotate through and bring reinforcing shots of cold air, with models generally showing one around Tue night, another in the Wed night/Thu time frame, and a much stronger one around the Friday night/Saturday time frame. These systems may bring some snow showers and flurries, but right now indications are that any precipitation will likely be very light. While temperatures will be well below normal for the entire period, current models suggest another round of bitter cold is likely sometime in the Friday night into Sunday time frame behind the more potent wave. Stay tuned.

Monday may see some slight moderation in temperatures as the upper trough begins to shift further east and heights start to rise, but of course details are murky at best that far out and temperatures still look significantly below normal even then.
