I did. Above 3,000 feet in West Virginia looks pretty good for wet snow.

 if YOU think   you are going to get snow  in westrn VA   with temps  39-43  degrees  and  925 mb temps    above  0z ... then you need to  slow down and  re think this

 because  clearly you did NOT look at  ALL the data

I think the confusion is that Wednesday is 12/16, not 12/14.  People may think you were referring to Weds event and not Monday’s because you said Weds 12/14.

Yes, thanks. Slight confusion over which event. We should try to be more clear when we are discussing. If Monday’s event trends colder, we can open a thread this weekend, and wait until early week for the late week threat. But for now try and be more clear

Not sure if Feb 2010 was also a hybrid. There were two lows, one off the OBX and another near West Virginia but I still don't think it fits.

I'm guessing just because there are two lows doesn't make a hybrid

Yea I would agree I think the primary will end up more west northwest of this particular setup but I also don’t think it drives as far north into the HP. We’ve all been around the block wrt that.

Fun fact with this event...the Ohio primary ended up stronger than progged, BUT the transfer to the coastal was pretty quick. A rare instance where up north into the PA mason/dixon counties boomed and DC didn't switch to rain. This was a rare wind for eveyone.

I agree. It will be hard for snow in Virginia on Monday. But West Virginia near Snowshoe could see a nice snow event

I know the general rule of thumb with cold dense air HP helping out naturally in a lot of situations, especially one anchored around St Lawrence Valley. Will 1036 be strong enough to combat the primary low pressure?

@psuhoffmantimeframe for the archambault event when the blocking breaks down? Jan 3 Blizzard?

Expand  

Jan 7. Should start in northern VA with pixie dust around 10PM temp near 18*. About a foot by morning. Some dry slotting during the day before a killer deform finish the next night. About 24” at Dulles. ~30 by you.
