Ummmm.....the UM model is in. Also inland, like ACCESS-G.

ACCESS-G is WAYYY inland. TOSS!

ARPEGE looking good!

Helpful link for everyone:

The spire model looks like the euro too

slight NW trend, more intense

The TPV lobe is way further north on this run (compared to the bad 12z euro run). Good!

Generally speaking, you don't want to see the confluence setup OVER WASHINGTON DC

Haha I hope this trends toward the tpv phasing with the trailing energy

wow, even the SPIRE model is moving our way. 00z: 12z

reverse jinxed it

I remember these well! before I knew to look at the 500mb stuff (and just stared at surface pressure and precip depictions) these were insanely frustrating. precip would build near the gulf with a low approaching from what appears to be the right angle. then the precip would suddenly disappear at the mountains, leaving DC high and dry....before it EXPLODED back onto the scene when the low bombed off the NJ coast. to a snow weenie with no clue why precip goes where it goes, this is one of the most painful events to witness. please be kind to surface map watchers.

RE: January 16th:

uh oh!

great points all. i just wrote all those wobbles off as "different cows being hit by rain or snow" but now i remember that there are cities in the midwest

Next weekend's cutter has been well modeled for a while. GFS remarkably consistent. I wonder if it's just easier to model inland storm systems? No messy coastal transfer/redevelopment? Or if there's something else about this setup that's easier for models to resolve? I suppose this just doesn't seem very complex. Just a vort orbiting around a well defined trough.

They have maybe 0.5% more skill than throwing darts. Mostly printing out old El Niño analogs from what I’ve seen

This seems extreme

January is ROCKIN'!!!

38F and light sleet and rain at the base of dc’s mighty Mount Hamilton

The 925mb hole setting up over Roanoke

YES. radar hallucinations have started!

For those who didn't get what "convection over the MC" is (me until 60 seconds ago) here's a neat little study where i figured it out: https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2022MS003503 Summary: Large-scale convection associated with the Madden-Julian Oscillation (MJO) initiates over the Indian Ocean and propagates eastward across the Maritime Continent (MC). Over the MC, MJO events are generally weakened due to complex interactions between the large-scale MJO and the MC landmass.

10 to 1! and half of this is from "tomorrow" (!!!)
