Remind what you said a few days ago about the accuracy of the GFS versus the ECM in Canada with the Northern jet in various regimes, PNA/EPO?

My location as well, forecast was 6 to 8. Total here was 3.5 inches. Saturday has potential, might even trend colder. Mount Holly states - It will still take several model runs to get a handle on this system. For now, will follow NBM PoPs and carry slight chance-chance PoPs over the area Friday night through Saturday, and even though forecast high temperatures are above freezing on Saturday, based on wet-bulb temperatures, the dominant p-type would be snow. High pressure returns on Sunday and Monday.

Without question. Many clustered West versus earlier far offshore.

I believe so, but could be machine generated. They came directly from the new update from Mount Holly. If you check out Richmond, VA they still have the mention of snow.

Well, it was in the actual forecast as a chance of snow yesterday, however, today it is gone. Zone 19709 Friday Sunny, with a high near 34. Friday Night Mostly cloudy, with a low around 22. Saturday Partly sunny, with a high near 35. Saturday Night Partly cloudy, with a low around 22. Sunday Mostly sunny, with a high near 36.

Mount Holly removed the wording of snow chances for this Saturday. However, they did discuss the potential. potentially active pattern will resume beginning Friday night and especially on Saturday as another upper-trough and associated surface low pressure system works its way toward the area. As expected at this forecast range, there are major discrepancies between each deterministic model, and from run to run. For now, went with mostly NBM probabilities for precipitation, though tempered them a little, and have chance PoPs for snowfall Saturday into Saturday night. From the overnight models, the GFS seems to have the most impactful solution for our region while the CMC much less so and a complete miss on the EC. Stay tuned for changes as the week progresses.

https://x.com/jhomenuk/status/1876047049285836995 There has been a lot of discussion about the phasing here. In actuality, there are multiple phases occurring - a first phase with a Pacific disturbance around 84-96 hours, and then a second (And potentially third) phase with a more "true" polar disturbance. Extremely complex.

https://x.com/jhomenuk/status/1876047026221424731 John Homenuk @jhomenuk This evenings GEFS has trended sharply towards a more meridional orientation to vorticity entering the US & a faster ejecting upper low from the Baja Days 4-6. Should this trend continue, chances for a strong Eastern US cyclone next weekend could increase. A very volatile setup.

Give it a couple days

18z Euro goes to 144 , maybe will show new trend or GFS like solution.

GEFS reacting and I believe more changes from the ensembles in the days ahead.

I am fine with even half of that

Full phase unlikely says Homenuk for next weekend, but might be some sort of impact in the East. https://x.com/jhomenuk/status/1875955036804825209

Very vigorous system , thunder noted https://x.com/burgwx/status/1875904212544127081 The major snowstorm is taking shape over the Plains as the surface cyclone is quickly developing and deepening — numerous reports of thunder alongside snow & sleet in Kansas so far!

Going to have to be a perfect track to prevent thermal issues. This windown always looked great for a powerful storm, now the question is locking in cold air and the exact track of the low. So many recent systems in past years have not worked due to a combination of coastal huggers, inland runners, poor phases, and other issues. @bluewave has spoken about this in detail the last few years.

Too warm East of the Fall line

Tomer end of the week https://x.com/burgwx/status/1875693350155592045

That would be a typical failure on several fronts. Seems we are going to avoid extreme cold, as the PV getting deflected. https://x.com/RyanMaue/status/1875357476503351668

Oh my . Leave early?? Drink a lot of coffee.

Also would this be considered a HA event based on the NAO reversal?

Extreme potential based on deepening. You will like this one for tracking. LETS GO !!

Your theory is holding water so far, with DC near jackpot zone and 48 hours to go. Creep North my friend.

Appears my area ENE from Baltimore benefits as well from the CCB, or at least assuming it is, as it moves East across the Northern areas.

Yet precip more North and NE with heavier amounts, coastal impact? Faster transfer.

Bamm Wx says reload. Webb says warmth is on the way end of the month in the East. Meanwhile over in the NY forum bluewave is talking about why we are not getting typical SECS and MECS.
