Good thing some guy named "Randy Legette" seems to know what's up:

***The modules are right. This could be epic. T hose loser at that American weather board or whatever are so full o f it**** I think the modules will be dead on for this one. I just called my sister and told her to begin preparations to secure life and property. Thanks wxsynopsis
Guise, that Ian dude is an admin at the troll board, american weather. FYI. Why do you have to bring that crap here. Go back there where they allow so called "meteorologists" with "degrees" to spread false information.

Maybe Bob or someone with secret Euro powers can tell us more, but this panel for next Monday morning suggests the overrunning snow potential still exists.  Having it come at night would help immensely.

One would think that would have to be OK for some of the area.  What's the precip amounts?

 

And does the Euro have its usual cutter?

hgr is the closest I can find with a decent chance. Looks like tracker is driving us all up there for a night on the town.

Looks solid for the N MD hills from 144-150-156...a little warm for I-95...not well timed with the best precip prob late morning. Despite that, it actualyl shows the 2m temps below freezing in the N MD hills. So probably even wet snow in the suburbs too.

 

The stuff from 132-138 is a bit lighter, but its not quite as cold in the BL. The 850 line stays pretty close to DC...so north would look the best.

I would also add that this evolution is probably going to change only 88 more times between now and the weekend.

JYO(Leesburg looks cold for the event) temps around 32-33. It keeps going north at 00zz and south at 12z

The only soundings I can find as a point/click is iad. There's a lat/lon function with a big disclaimer about "not being that accurate". lol. I stick with iad so I don't end up in a weenie witch hunt.

agreed but both globals have been showing best rates in the warmer side. I think the most supportive thermals are going to be N no matter what happens here. I can't see the cities having bl temps aob freezing AND getting good rates at the same time. We have to just hope we get a period of heavy enough to stick for a bit. That's my 2 cents anyway. Prob not worth a penny.

Doesn't look all that bad, if I'm reading it right.  I assume the first column is ground temp and second is 850?  One would think that the 12z to 18z period Monday might be good with that much precip falling during that 6 hours.

Yea, a line from you to hgr looks pretty good verbatim. Parrs looks ok too (psu land and westminster etc). The rest of us are facing another same ole same ole. 

 

It's nice seeing a colder solution again though. I don't like the flow all that much. w-e riding along a boundary. Sure would be nice if we can get a dome and some amp before it starts. Just a little more sw trajectory with a some sort of hp nosing down would make a huge difference. Odds clearly favor nw + elevation. Cities shouldn't be too excited.

A lot of if's usually means a NOPE - Not for you - scenario

 

Reality here is that we are in Spring and no one needs to get hopes up... they would only be dashed.

Not a very science based post. The reality is that models are emotionless. When a model shows a scenario, especially the model many consider the best, it is certainly possible. The other reality is that we are barely into met spring. Snow is possible. November is met fall. Is snow in November a shocker?

Whether it happens is up in the air. This weather event has nothing at all to do with the previous 50. There is no usually. It is a unique weather situation. At this point, it can still end in a lot of different ways.

I didn't say sleep on it though. We just had a storm bust 2 hours after it started. Using 5 day lead model runs to make a deterministic call is precarious at best. 

 

Below normal temps with precip in the area possibly falling at night should be watched even if it's low prob.

here is my first call

IAD 2-4

JYO 4-8

Rockville 8-12
