Surface temps are not pretty on 12Z Euro after HR 66... above freezing for the rest of the event east of the Blue Ridge...

that high running east part still kinda sucks.  we always end up with temp issues even when we think we're fine. though lay down some snow before then and we probably are if it stays heavy.

Is there decent snow as well after any mixing (in the CCB area), and how area-wide does the Euro show that?  Hard to tell from some of the discussion, though it's clear there will be mixing issues in and around the metro areas.

 

yes...another 4-8" Thursday afternoon...but...surface is kind of warm....it may be 32-34...but that would probably still be 8-10:1 ratios in moderate to heavy snow...possible  -ra/sn as we wind down

I'll make sure to report low snow totals and P groups at DCA so you weenies have heart attacks.

 

 

just be honest and pay attention...we know DCA will be a little low due to location...we just ask for an attentive reading for big events....that's all...I think you have done quite well with snow readings the last couple years (liquid a different story)...keep up the good job!

If the ULL is as powerful/strong as some of the models say... we should stay snow even if it is 32-34 at the surface as long as the rates are good

It's a solid 6-8+ for DC before we ping, and then who knows what

Jason and I were thinking maybe 1993 type amounts for us in the city and points east hough this early we're not gonna put out any explicit accumulations and that the western guys could really cash in.  I sort of favor the Euro since it fits climo a little better than the GFS and nam.

Thanks.  That makes sense, I was just curious whether there was anything after the mix.  So there seems to be a general consensus of some kind of snow-sleet-snow sandwich here (at least metro area), and a lot more in terms of snow in the farther western burbs.

 

Kind of disturbing to have the Euro surface that warm, but right now that's a detail I suppose.  That "back end" part you describe almost sounds like Jan. 26, 2011, around to slightly above freezing with mod-hvy snow.

different storm but yes...maybe a useful guide for amounts...something like 6-8" for DCA (they'd do better if the euro is right), and 10-12" NW DC....that would be a major event

Just checked...  1993 was a dissapointing 6.6" for DCA...  That's prob more realistic than the 12-15" DT just assessed the Euro as showing.
