January 2026 Short/Medium Range Thread

The GFS isn't just often wrong these days, whatever has happened to it, it doesn't even correct until the event is actually happening. 

[GBOVolz]

I think what we're hoping for is a lee-side low developing in response to the upper-level energy moving through. If the surface low tucks closer to the coast, it could indicate slower progression of the overall system due to the upper dynamics, which would give more time for precipitation to wrap around and develop over the eastern parts of TN

You can sometimes get troughs where there’s a wind change on the backside with this much CAA spilling in. Any kind of convergent area to create more lift will be appreciated. lol

The GEFS AI is definitely showing a westward trend with the moisture

[fountainguy97]

Euro-ai. Significantly west

[fountainguy97]

So all we need to do is hate on the GFS a bit and now the euro is heading to the gfs lol.

One thing that looks nearly guaranteed is the coldest air of the Season this Weekend.

So the question is do I hate on the gfs again before 00z for double or nothing?

Euro AI…and this is just 10:1..substantial westward expansion

[Reb]

OP caving as well

[TellicoWx]

That's fairly significant shift on AIFs...little extra moisture gonna go a long way. Looks like a solid 3-6+ event on it imo

[Kasper]

Have we not been down this trail of disappointment and misery?

I’m ready to be hurt again, but that’s probably  30 years of sales experience and dealing with rejection helping me out……lol.

I feel this the let down is real!!

[Vol4Life]

That was a significant shift for the Euro.  We are still a couple of days out. Still time for it to move some more!

And that “should” bring precip with it if other cold winters are used as analogs.  I don’t trust the coastal enhancement, but I do like light snow from the northern stream with high ratios.  If this turns into a NE blizzard, NE TN and SW VA often finds themselves in that axis even if just light amounts near the genesis of the storm.  If DC can end up in the storm, that is usually a good sign for us.  Kind of a weirdly displaced Miller B.

[Carvers Gap]

My rule of thumb…get the slp west of Cape Hatteras if we want help from the coast in E TN.  Otherwise, we need lift from the west slopes of the mountains.  I still wouldn’t discount a LSL…anyone see it?  Lee side low
