January 2026 OBS and Discussion

[Krs4Lfe]

Models punting the originally expected "good pattern" through first week of January. Onto the next week, and the next week, and I bet the week after that. Mild and warmth returns to most of CONUS except northeast starting next week. No sustained cold or snow for most of country. We might remain cold, but it'll be hard to snow with such persistent warm all around. Terrible look

Wind has been absolutely insane. My Tempest is NOT in a good spot for measuring windspeed and it’s routinely returning 30mph gusts, higher than I’ve ever seen from it except in like 2-3 other instances which were one off gusts.

You said the same thing about this month. Take a break.

The cold will definitely take a break at some point, but it took a break in every good winter we’ve had. We don’t live in the Yukon.

of course it will take a break but smaller breaks through January before the next arctic front comes through - also those great lakes cutters especially on the GFS are hard to believe with that massive blocking stretched across Greenland and westward - GFS has done this before trying to force the LP's to far into the block

Be careful dismissing those cutters. Many hobbyists have made the mistake of discounting cutters due to a block...yet we have seen many cutters slice right into those blocks like a warm knife through butter.

Interesting setup. Probably an inch or two type deal but nice refresher and possibly more with just a little better/sooner redevelopment.

At least half of that is 1/1, although I'd be happy with a fresh coating each day...

Wouldn’t surprise me if east end of li ends up with 2”

At the 30,000 foot level, the EPS, GEPS and GEFS ensemble means are far more similar (for 95, inland and even through interior PA, NY, New England) out to 360 hrs than they are different, indicating pretty good agreement on the general idea of a snowy period with most of this falling after 1/5 (all have <1" for most of the 95 corridor from DC thru NYC and even inland a bit through then).

 

 

The EPS, GEPS and GEFS ensemble means for snowfall through 1/13, 12Z, generally dropped a decent amount in the last 24 hours (except for the GEPS north of NYC and not because any snow was forecast to fall over the last 24 hrs), presumably reflecting the pattern not being quite as good for cold and snow as it was 24 hours ago.  On today's 12Z ensembles through 1/13, 12Z, Edison, NJ (25 miles SW of CPK, whose numbers look wonky on these graphics) dropped from 4.0" to 2.0" on the EPS, it fell from 3.5" to 2.8" on the GEPS and it fell from 3.5" to 2.3" on the GEFS.  Picking one more point, White Plains dropped from 4.5" to 2.8 on the EPS, it jumped from 3.7" to 4.8" on the GEPS (the only increase) and it fell from 4.3" to 3.0" on the GEFS.  Given how far out these go, I'm not even going to attempt to explain any of this - just noting a modest to significant decrease for most of the 95 corridor at least over the last 24 hours.
