The 0z Euro continues to be steady by yet again tracking the Sunday pm low under PA bringing the chance for snow. 

Long way to go, but it’s good to see the Euro & GFS now coming to an agreement. Let’s hope that it holds and improves more this week.

German house model now has similar look for this opportunity as well.  GFS is an unmitigated dumpster fire.  CMC is workable for much of true central/northers for next week.  

I'll be back in a few days.....in hopes that our pattern change thats been looking to start later this week starts throwing some better looks up.

I was surprised to see that this has only been the 5th warmest January through the first half of the month, but the one thing that we haven't had is a couple of days of extreme (highs near or above 70) that we've had in a few years that are higher. Still, a remarkable turnaround considering some (but not all :) ) of us were shivering around Christmas.

Great run of the 12z EPS for the advertised pattern for the last week of January.

The southeast ridge is pushed well off to the south & east. 

Temperatures look to be bit below normal for us.

This has the look of systems running from the south central states to off the coast of Virginia. Hopefully we can line up some moderate snow or snow to mix events for the last week of January.

Lol, not according to the 12z Euro… 

It has been steady for the last 2 days delivering snow to most of us by next Monday.

having the Euro/CMC/Icon showing colder solutions is good to see.  It'd be nice to see the GFS go back to being useless like we once knew it to be...:P

Turns out not all volcanic discharges are the same . Large Eruptions with high sulfur emissions cool the atmosphere . Large volcanic discharges with high water vapor emissions warm the atmosphere, and can do so for a much longer period than a cooling event, because water vapor is lighter than sulfur and will go much higher than other aerosols emitted by volcanoes .   The Tonga eruption emitted very little sulfur compared to other large eruptions  and discharged massive amounts of water vapor, both due to its geography.   Probably not a great thing for winter on top of a Nina.

The GFS Op has been pretty useless, especially since they supposedly upgraded it a couple of months ago.

Yesterday it was way west, then this morning at 6z the GFS had the Sunday/Monday low off of the DelMarVa just like the Euro has showed for the last several runs, but 12z & 18z wildly shifted way west again….0.0 consistency in the medium range!

they often promote warm seasons then average but hardly headline the very cold at all. like this fall it was one of the coolest I can remember but didnt talk at all about records. just daily about how cool it was.

This fall was not cold at all. At least not in south central PA. Almost half of October was above average and remember just how hot it was the first 2 weeks of November? The only time it got really cold was around Christmas for a few days. Another thing that seems forgotten is averages increased 2 degrees all over the state because we're now using averages from 1990-2020. The old averages we used were 1980-2010 which were 2 degrees cooler on average than they are now

There is still no agreement in the major weather models for the Sunday/Monday storm chance.

The 6z GFS still cuts the storm to Toronto bringing rain.

The 0z Euro now shreds the system and slides it under us with a little light snow by Monday evening.

The 0z Canadian has a compromise with snow to mix by Monday evening.

I’m not focusing on much else beyond this period until this storm is resolved.

You just can't trust government agencies or fellow citizens to keep track of temps, snow totals, or classified documents these days.

Looking at overnighters, I'm increasingly encouraged by the changes showing up aoa 100hrs+, as the PAC regime change starts to show and we get ridging popping up around the Aleutians which likely holds the key for better times as we can tap into the cooler temps.  This isnt quite the look we want, but once we get out to 144 and beyond one can see that cause/effect in the conus.  By 180 pattern becomes established...and chances should come.  Lets hope it holds.  Better for the show to start late than never.
