Today’s Eps extended have the mean MJO wave dying in Phase 8 inside the COD after a brief stint in the warmer Maritime phases. That would probably be a good result if right, but again it's a mean of a lot of different member results. I've attached the RMM plot for the MJO along with the Euro time-longitude plat showing the easterly trades feeding the Niña base state will end around 2/11 IF it's correct. That too would work, I think, with enough time left in the season for 1 or 2 last gasps...hopefully.

If you took the effort to look, you'd see it comes over a short window and not a little at a time. But you have you agenda, so...

12z EuroAI is weaker with the snow on the 5th, though still there. Pure guess of 1-2" max. 2/6 is warmer than last run and looks like snow to start in the northern forum and snow/mix in the south, then all to rain for everyone. Don't see temps getting as warm as the operational around the 6th/7th, with warmest around the 9th/10th before another cold shot leads into below. BIG threat on the 12th-13th which is showing up on both operationals and definitely the ensembles. Eps really likes that period. The run ends seasonably cold and a another cold shot looking to head south out of Canada.

Pretty decent snowfall mean on the Eps. Better than yesterday I believe.

Enjoy it while it lasts if you enjoy it because...

All is dependent the boundary location. Euro AI has probably been the best if you want cold and snow. Canadian if you want warmth.

6z Euro AI is decent for 5th-7th and end of run with a snow threat and cold.

I didn't post anything because the Euro site made it look much more tenuous at that time. I know it's hard to see, but the 0-line is north of Baltimore on this map and is moving north by 180hrs.

Yes...2 waves. One early on the 5th and another late 6th into 7th.

AI 18z run supports snow on the north side (N&W) of Baltimore this time, but it keeps switching back and forth between N&W and south into Central VA. It does show a very wet storm around the 12 and 13th, but is a little too warm south of the PA line, if even there. Plenty of time to go either way.

18z Gefs likes the period from day 10-14. Top map is total snowfall thru 240hrs and bottom map is 336hrs.

If I said 2/11, JI would have expected a second storm on 2/12.

18z Gfs has the 2/12 storm but a day or so earlier.

Ahh...No! Aldie and I have been posting on these boards for 20+ years and bust each other's chops now and then.

Thanks for the jinx.

Eps with the best snowfall mean of the 12z runs.

Today's Eps weekly MJO mean forecast. Would be nice if the MJO did just this and let our luck rest on something else. https://charts.ecmwf.int/products/mofc_multi_mjo_family_index?base_time=202501290000

AI has the 2/12 event. Definitely starts as snow probably DC north but likely ends as something else south of PA line, maybe further north from thateven. Again, wait for TT/WxBell. End of the run has a trough in the east.

AI still threatening for the 5th and 6th, though it keeps changing here and there. All I'll say is that it looks like most in the forum gets snow at different times. Probably light to moderate at best. Too hard to parse through 3 separate maps to figure it out. Wait for TT or WxBell.

At 360hrs, it's loading up for another overrunning event, but this is a little warmer to start, but not by much.

It isn't?

About time I get bullseye for an event.
