Not sure what that means but it does have that low of the dry slot coming in quick with one swatch north of us and then stuff reforming to the east. Sort of an anemic miller b look where if it were cold we might get 1-3 but at 35 or so, probably not. 

verbatim, it looks like slop after snow at first

the surface temps do cool with the heavier precip (relatively speaking), but by that time it's too late

we probably need at least 2 more degrees colder, at least in the closer in burbs, with more in downtown DCA & BALT

a bit of an inside joke. Yes, definitely anemic.Models have been showing the separation in various ways. Best lift and precip from the primary is north. Secondary delivers rain favoring the eastern half of the cwa. This map kinda sums it up in regards to snow. This is through hour 57 so not all snow east of Fred/loudon county.

It's obviously the NAM at 57 so that should be noted but it could definitely be a clue that the best lift and moisture skips us with both features.

A lot of that is FZRA.

 

You're saying the NAM categorizes FZRA as snow in it's snow depth?  The map is snow depth too, not a map of new accumulations. See F00 where there is actually more snow in many areas, including across Maryland.

It should be a rule to have to leave date/fhr, map legend and title on images posted.  We know it's f57 NAM, but beyond that, not much so it's hard to follow what you're saying.

Ahh, yeah your right. I quick looked and assumed that he was posting accums, not depth. That makes much more sense. :lol:

It's hard to follow a precip hole?

 

I don't like posting full maps all the time. Especially when just illustrating a detail versus full output.

Dang...Happy Hour is quiet...Anyway WPC gives the I95 corrior only a 1-5% chance of greater than or equal to 2"...Tommy T was just on in Baltimore, showed the RPM model snowfall, nothing for DC, inch or less for close to Baltimore...Dont know a lot about RPM but I know its the in house model for these TV Schmucks.

although I think most of north central md gets accumulating snow before a change over, I don't think it will  be anything more than an inch or two, . just not our storm in Maryland, unless ur   west of  Westminster in carroll county then maybe youll see  2 inches or more

I admittedly haven't been following Saturday very closely, but 18z GFS happy hour doesn't look particularly happy to me.  850s are fine when precip starts, but the column is above freezing below 925mb for almost everyone except the very far N/W zones. 

I agree, this isn't  our storm,  cant get them all, im happy we got 2 snow events in a week and its only dec 12th, a lot of winter left, infact..... techinally winter don't really star for 9 days ;)

Bob the NAM isn't showing stellar consistency on its precip. Top image is 12z run 24 hr precip at 7 pm sat., bottom is same time frame 18z run. Not sure the NAM should be trusted.

I wasn't really using the nam as a precip total tool with my post. Just just pointing out that it shows 2 precip maximas. One NW and one SE.

 

We are in the middle so our area will likely verify on the low end of totals of the front end precip. It's not just the nam showing off and on. 

 

I haven't seen any model run show good rates with the front end precip. At least nowhere near dc/balt anyways. 

 

I'm out.
