Took a blizzard to shut down Valpo in 2007. Only weather-related day off I got in four years. Times have changed.

I'd have to disagree with you there. The MJO, the forcing mechanisms in the pacific are where we get the PNA and EPO, which are crucial for cold air delivery to the SE. It's not the end all be all (it's more complicated of course), but where the pacific forcing is to me is step one to understand the base state. The forcing has stayed in the Maritime continent the majority of our winters, and I think that is the main reason our winters have been so bad for so long. It rarely stays in the cold sections in winter. It all comes back to the forcing mechanisms in the pacific imo.

I love it! We need a thaw. 16 this morning was 13 degrees colder than normal. It was 65 degrees for Christmas 1965. That was 60 years ago.

Still have a snow depth of about 3”. Some light to moderate lake snow potential today and Sunday before the torch.

We have seen below normal temperatures every day with the exception of one day since Thanksgiving Day. This pattern looks to continue for at least the next week. We warm enough today that except for areas in Northern Berks and Lehigh counties we should see mainly rain showers. We turn colder tomorrow and will see some light snow chances both Friday night and again during the day on Sunday.

37 / 29, Highs in the 40s, will make this the warmest day through next Wed. Rain/ showers pushing through, cloudy once to mid morning. Overall cold Dec 11 - 17th with the coldest 72 hours Sun - Tue highs sub freezing in places one or all 3 days. Snow squall / showers overnight Sat/Sun possible with arctic front reinforcing cold. Moderation to and above normal by the 18th into Christmas as ridging noses east.

Absolutely something to keep in mind. Like dendrite said...this could easily turn into an overrunning pattern. Sometimes its easy to get caught up in the H5 charts but the sfc may not always connect. Remember back in like 2017(?) the Great Plains were under like 560 heights and it was widespread single digits at the sfc lol because they had that stout Arctic high.

Just went to a WWA here for 2-4" of mixed precip and a light glaze of ice, Beats plain rain though.

Nam gets some light snow in on Friday, DC to the south at around 10.

Thats fine with me. I read previous times where Decembers that featured a mostly -PNA have a following Jan with a overall + PNA. Hope that repeats next month, along with some timed moisture. Even a little snow would be nice.

Over 90% success rate for 14 out of the last 15 La Ninas spanning 30 years so you are mistaken.

GFS is soupy 80s to Virginia where they have deep pack now lol .. I can see Christmas week delivering a nasty ice storm for the northeast GFS has the cold in Canada ready to be tapped .. Kevin may get his dream, a very dark Christmas

This is going to erode most of the negative departures we have for the month. The worst of the worst.

Might as well just close the shades till January: wide left, wide right, wide right, wide left, wide left.

Yeah, it's increasingly likely we see a reshuffle, which makes sense obviously because we're running massive negative departures, but the devil is in the details.

Wolfie?

Sort of a chain reaction effect, with short term changes with the current trough in part leading to the changes for the clippers.

Lots of cold air lurking just up north. This warm up won’t last long. Unfortunately it may happen right at xmas

...and a Melt Outbreak for some people here lol

someone said wait til 48-72 hrs to jump on board-that makes sense too vs a week out

right... 74 in Central Park, and 68 in BTV, too

LOL, the CFS from 00z is the best model of all for the 14th

I drove up to Philipsburg this morning from Three Springs and it was a consistent 25°F on the ride up and temps got to about 29°F currently. Cold rain coming today. Beautiful.

Merry Warm up. Need to go back in time to get even a normal winter. I miss you Nor'easters and SECS/ MECS .
