The ensembles really keep thinking we’ll get into a -EPO gradient pattern eventually!! Been advertising it for weeks now and perpetually been D10+ away. What I do takeaway is increasing confidence that Canada will NOT be entirely flushed with Pac air, so hopefully we can tap a solid airmass again at some point after 2/25.

i took your signature...divided the snow by the years...you are averaging 26 inches of snow pretty much since 09-10

Yeah, bolstered obviously by 4 historic years in there. Median over that period is 19.5”. Both are higher than the “true” long term mean/median by some amount. I’d guess my true median is pretty close to last year and this year, 16-17”.

Yeah that's what I was trying to point out with the EPS map I posted yesterday. If the Sh!t pattern is relatively brief, should still have some workable cold not far to our north, so once the east coast ridge flattens we have a chance for the cold to press south some and get a wave to track along the boundary.

GEFS does just that... this is March 2015-esque

NOT saying that this March will be anything that extreme, but the advertised pattern could certainly deliver with overrunning events riding the boundary

Weather Will said that we were done for the season though.

I'm honestly surprised there haven't been any "confused" reactions to this yet since the map has yellow/orange over us.

That said...those two H5 anomaly maps are astonishingly carbon copy-ish looks.

I posted a similar h5 map from around the the same timeframe off the EPS yesterday and I got at least a couple :blink: 

I think some people have a hard time interpreting a smoothed mean (understandably), and also context matters.

Didn't like hours 360 through 384 ? Lol

Yeah that was great and all, always like to see snow and stuff on the long range GFS and it was a decent storm. But tell me that this H5 with cold air and a high pressure in place with a low just south of the Florida panhandle that this would not of been the main storm.

I think DC itself struggled, but plenty of us just north and west had a decent month.

Edit: What WxUSAF said.

I can’t remember the year but I remember it was one of the few times I saw -0 temps and it was March.  Saw -4 driving through Bull Run Battlefield. Maybe 2015.  Negative anything is rare here any month.

Lots of -5 to -10 in central VA that morning.
