January 2026 Short/Medium Range Thread

We just need the vort to wrap over West Tennessee vs East Tennessee. The Canadian and GFS do it there, the Euro isn't as wound up and brings it further East. The Euro Ai is closer to the Canadian/GFS than the OP Euro.

[John1122]

At the end of its run, the RGEM looked like it was going to wind up similar to the GFS/Canadian.

Any GoogleAI updates for 12z and/or trends?

[John1122]

The 12z Weather Next should be out in a few minutes.

[John1122]

Weather Next is delayed for some reason.

Looks like Google Weathernext v2.78665  pretty well held with the upper low bringing snow, but that's about it.

With. 20:1 ratio, that’s likely a 2-4+ for ETN with amounts increasing for NETN

[John1122]

It was ever so slight, but the Weather Next moved the precip slightly west and slightly more for most of East Tn vs 06z. So a small step in the right direction.

It's crazy to see snow dumping over the gulf stream off the South Carolina coast. But here we are where it snows heavily over warm ocean areas but avoids it at all costs for East Tennessee.

Will be interesting to see what the High-res models do with the ULL moisture as they get into range. Even without the bomb Eastern areas may actually have a shot at the biggest snow of the year.

[John1122]

From that Weather Next run, ratio'd since temps are in the single digits and low teens and the entire column looks like a North Dakota snow sounding, I'd say 1 to 1.5 inches around Cookeville, 1.5-3 inches along the Plateau west to East, 1.5-4 along the central valley of East Tn, 3-6 for NE Tennessee/mountains.

Maybe the low will track in a favorable direction for East Tennessee.

After what seems like a train of downslope events, i'm sure most in our area would sign up for a 2-4" snow, especially if we don't have to use that term.......

If I can get 2 inches from this, I'll be happy at this point. The Euro being a complete whiffer is a sadly decent chance to happen too.

That’s the one I use. Very handy

These guys do a good job. Nice write up here for the weekend
To summarize… they are on board with a faster phase and a more western track
