Looks like the post-Xmas 1984 warm shot. ORH hit 70F in that. Latest 70F on record.
-
If the solution ends up verifying pretty close to the AI models, that would definitely be a big win for them. They’ve been way steadier than the regular OP runs.
-
06z euro def brought it back…esp for SE areas. I’d want to see the 12z suite as a whole look better though before believing it.
-
Def quite a good change on the 18z eps
-
Fwiw, the energy responsible for the Sunday system is over Siberia and crosses over north of AK tomorrow night and finally into Canada by Thursday during the day. So we could still see some decent changes.
-
Yeah SE Canada does make a difference too. Ridge axis is a little west on that 18z run too…so even though it isn’t taller, it’s better oriented.
-
That’s a pretty decent sized event for recent standards over SE areas. But I think decent banding would prob get back into interior too.
-
That’s CAD-city on that setup.
-
Dang we lost our 70F Xmas day
-
Both AI models have been relatively bullish on the Sunday threat.
-
18z GFS still a whiff on Sunday. Icon was pretty decent though. Always good to have that model on your side.
-
Thankfully basically zero similarities between those two years at the moment. We’ve had a different Pacific regime compared to recent years so far…that very strong WPO block is not something that’s been there. In recent years, we’ve seen a generally strong positive WPO which will tend to mute the cold…the negative phase has the opposite effect which is probably why our cold has been overperforming in the medium range.

When you have summer heat ridge heights near the winter solstice, I'm guessing it's hard to wash that out even with other ensemble members.
-
Even the Euro aloft might argue for more QPF being wrung out a bit further inland...not an uncommon model bias for all guidance in keeping thew QPF too close to the low-level thermal gradient. It's why I think that run was pretty good for SE MA despite most QPF being centered over Cape/Islands. But yeah, that could get juicy pretty quickly if you displaced the PV lobe even 75-100 miles west.
-
This will be verification
-
Actually a nice look for SE MA.
-
-
Might be able to go 70F if we pump that ridge enough
-
Yeah same season....April '82 was the cold blizzard.
-
That was a big winter and quite cold....esp January '82. Very cold month with decent snow. Same month as the Air Florida crash into the Potomic with lots of ice in the river. Dec '81 was very snowy in New England both north and south.
-
Just take the mean of the GFS and GGEM
-
We actually have 1980s low temps too this time.
-
It's still there but it gets ground up by low heights to our northeast. I actually thought it might improve at first because it was lsightly better out west....but the vortex to our northeast keeps the flow too flat to allow the WAA to get going.
-
2007 actually pulled it off in Boston believe it or not....they didn't get a real snow event until the 12/13 storm (interior N of pike had some in the 12/3 event)
-
Yeah seeing Virginia get multiple snow events in early December doesn't help. It's one thing for that to happen in mid January but early December makes it worse. It's also pretty rare to get this type of cold for 10+ days and not get much or any snow to show for it even on the CP of SNE. We did get a stretch similar in early Dec 2018....though not quite this cold...and we got skunked while a huge storm hit VA. But fewer people were on edge in 2018....we were coming off an epic winter.
