December 29-30 storm.

The Euro does look good for a moderate event around the DCA/BWI metro area this weekend. However, I always get a little nervous with these storms that have central MD as the western cutoff for the "good snow" and the best precip is depicted further north and east. Unfortunatley, I've seen storms through the years with this precip pattern, shift NE and leave the DCA/BWI area with little precip. I'll be closely watching the 12Z Euro for any shifts in precip gradient (hopefully stable or even further west)---do not want to see the dreaded east shift.

I feel like this is going to evolve into a major storm for areas further north, but DC will still see a 3-5" event. The EURO has looked close to something big for some time, and I think the same trend with this past storm seems to be occurring with the new one (further N&W, which in this case is a good thing). Will be the first white New Years in quite a while, I think?

Just woke up... should have stayed awake for the party last night... looks like it is evolving well... the gfs looks to support all snow... what about the ratios? With this thing really not bombing until it gets to our north and east... I am hoping we can sqeeze out 10:1.. maybe 4-6?

Edit -

yuck... from NWS- A WIDE AREAL

RANGE OF RAIN-SNOW MIX FOR THE LATE MRNG HRS...CHANGING TO RAIN OVER

SRN MD AND THE METRO AREAS HEADING INTO THE AFTN HRS

Still have p-type issues?

The 00Z Euro and 00Z GFS (06Z has trended towards the Euro) are almost identical at the 500's @ 48 hours as the low starts moving up from the gulf states. The only minor difference is the fact that the Euro is slightly stronger with the southern low and the GFS has slightly lower pressures to the north of that southern low. I find it interesting the end results for our region just with those subtle differences.

Im stuck with phone models till later but I scanned through everything. My best guess is to go in between the gfs and euro (cliche. Lol).

Euro is a thing of beauty but let's be honest, do the various setups at 5h really support a classic dc-me significant snowfall? I guess it's possible but I'm not biting there at all for now.

6z gfs looks fair. I could see that type of evolution but a bit juicier. I also don't think freaking out on the column is worth it either. How have the last 2 events played out? I think this is still a very good chance at all snow in DC.

There are 2 more events on tap after this weekend as well. I don't care what the exact solutions say right now. There is good spacing and active jets. Fun stretch of tracking for sure.

if the GFS is the solution better hope you are as far north and west as possible

yes...and when I brought them up last night, i was told I was being too IMBY....the GFS has looked questionable for at least 2 days now

Even though we are at the outer limits of the usefulness with the SREF's you have to like the fact that over the last 24 hours of runs they have trended away from a GFS solution and more toward a Euro solution in the setup leading to the Saturday storm. They seem to be evolving away from the more strung out look with lower pressures to the north that the GFS prefers, to the more consolidated look that the Euro presents.

Thinking more in between honestly. Just like with the Xmas eve the ns ended up not being as dominant and the column went cooler. Just a hunch but I think surface low pops south enough to give mostly snow but prob not some big juiced up system with a classic track. Just a wag but things keep looking familiar to me.

the 6z GFS is a definite improvement.....I imagine this storm will be like the others...people who live in places I have never heard of with one traffic light will post pics of their +SN and 4" and I will be oscillating between precip types and taking pics of cartops

LOL- funny post. But I know exactly what you're saying. Not this time though. We are going to witness the tried and true euro unwrapping and gfs amping. I love being a weenie. Busting had no consequences. Haha

i'm going to look at the NAM now since I am desperate and hope it gives me snow...if it doesn't no big deal...We can dismiss it like we usually do

This has a progressive look to it and I don't expect it to wrap up too much. I see a light overrunning event with 1-3 inches over a wide area. I just don't see a strong enough system to do much more than that. The one big question I have is if the light precip will be enough to overcome a questionable boundary layer.

I looked the the euro on wunderground since you can get 3 hourly maps and it has a wind stream line map that shows dc with easterly winds even with the low developing to the south as it implies a weak low to the northwest. That's still the crux of the issue for you and me. My boundary layer is above freezing on the Euro. I think the GFS, even the 06Z would be mostly rain for the city and points southeast or really sloppy snow. The ncep precip algorithm has us as rain. We need the Euro to hang tough. The Ji's of the owrld probably do well with either model.
