Flake size here has went from about the diameter of a pencil eraser, to about the size of dimes and nickels now. Temp is now down to 27. -

RGEM remains rock steady with 4+ inches from the Plateau eastward, and 2+ for Chattanooga. Big run of the ICON and it's fallen close to in line with other models after being far east all day yesterday and the day before.

Jan 30th-February 1st 2026 Arctic Blast/ULL Snow OBS Thread.
John1122 replied to John1122's topic in Tennessee Valley
Finally getting that foggy look, the flakes are small, the temp has dropped a degree and snow is beginning to cover up raised surfaces where the snow had melted off. -
This is a pre-event portion. Most accumulations are supposed to be tonight. My forecast for tonight is 80 percent snow, low 12, accumulation 1/2 inch. It's MRX vs the Euro and all other modeling except the NAM now.

Snow beginning, 29 degrees. Already have snow on the ground mostly, so everything will stick. We seem to get this and then I get a lull per my forecast. -
Euro at 12z Maintains 3 at the center of the Plateau, rising as you head east. 6+ knox east. 1.5-2 in Hamilton Co.
