We get some glaze on trees every year, but this is the most I have seen in 10 years in this location. It is hard to tell from the photo but it is well over a quarter inch on trees, mailbox, etc. I can’t tell from the picture but I will take your word for it.

MillvilleWx Posted December 17, 2020 Share Posted December 17, 2020 Definitely learned some things with this storm. I tried to be even keeled, but once again, I got bit some on the warm air intrusion in the boundary layer. I wrote a tweet thread about it. My estimates were still okay, for the most part. My high ends needed to be trimmed some out west. I’m glad almost everyone in here got some snow though. I certainly miss it and being back home for these events. . 2 Link to comment Share on other sites More sharing options...

I would never tell you that. I wouldn't use snow totals from hundreds of miles away to tell you that it was a great storm for your backyard. Kinda silly, but weenie psychology is a fragile thing.

Rule of thumb... you never want to be in the jackpot With a Miller a 4 to 5 days out. Nine times out of 10, the storm is coming north. Don’t get me wrong, I was rooting for this too. Just never seemed realistic given the time of year. This had the interior written all over it. This was a classic pre winter nor’easter. this run also depicted the 850 low closed to our south, with NE winds. That Never materialized. We were an 850 low closing away from seeing 12-24 area wide Link to comment Share on other sites More sharing options...
Herb@MAWS Posted December 17, 2020 Share Posted December 17, 2020 While we/Columbia seem to do OK compared to many here, living in Columbia creates it's own sort of snow neurosis: Too far south and east to benefit from the higher 400'-800' elevations and generally colder climo 30 miles to the N and W; too close to the Bay influences for situations like yesterday; and just barely west of the usual -- and seemingly very real - -"fault line and I-95" higher snow forecast cutoffs. OTOH, we do sometimes get the MoCo-HoCo deathbands. Plus, it's a nice place to raise kids! 1 Link to comment Share on other sites More sharing options...

A lot to analyze in hindsight. I'm not sure any modeling system can claim victory for this event, but several did have some important pieces to add to the forecast puzzle. GFS was pretty bad overall... GGEM was the first I think to sniff out that the primary low would form along the SE coast and not be in the OH Valley and then jump to the NC/VA coast. Euro did overall a pretty good job being on the western edge of the guidance and consistently showing a lot of mixing, even when the GFS/GGEM were snow bombs for us. NAM did well even from long range with the very expansive area of mixing and rain. I'm not sure the NAM did well on the track in hindsight, but it definitely was value added. And actually the HRRR did surprisingly well from range with the WAA thump. NAM, particularly 3k NAM, missed that entirely even from 6hrs out. 2 Link to comment Share on other sites More sharing options...

I never said that some place 400 miles away wouldn't get good totals. LOL I am not verifying my forecast across half the damn country like HM does...

RockabilyJunior Posted December 17, 2020 Share Posted December 17, 2020 Also, the GEM model is almost always one of the coldest solutions. If the GEM isn't showing snow, then it's probably not happening, but it often over does the cold. It doesn't mean it's always wrong, but as other people have mentioned, you can generally rely on a move NW, or at least a slightly warmer solution to ultimately verify.

Another one of the storms where warning signs showed on one or two model runs a few days out but because the overall trend wasn't a total disaster it was assumed they were outliers. Mesos came along and said there was something to those bad runs. Thats why they exist. To nail down the small stuff because for as good as globals are they can't get specific local dynamics nailed down until the storm forms and gets going. All i know is that the power of warm layers cannot be denied and when they are modeled they will perform. At least IMBY. Blame warming oceans or whatever. Until we get a Krakatoa I will just assume snow will be more and more difficult to get DC east. 2 Link to comment Share on other sites More sharing options...

We definitely don't have the climo of the cities and the airports, but we get fringed by the "N/W suburb" events usually. But being above the fall line, even barely, is noticeable in situations like this. We doubled BWI's snowfall and it's only ~15mi away. 1 Link to comment Share on other sites More sharing options...

Tell ya this though ... we keep getting the storm track we’ve had for the past few months we are gonna be golden. 2 Link to comment Share on other sites More sharing options...

Feels like there might be enough cold air around this year to cash in from time to time. Alot better than last year.

Until we get a Krakatoa I will just assume snow will be more and more difficult to get DC east.Thanks for the feedback guys. It was definitely a tough forecast to nail down. There wasn’t a classic phase of the streams that can make things a little easier to track in traditional Miller A events. This was a hybrid with a further north close off at 7H and that really hurt the chances for a bigger storm, along with the boundary layer warmth. The HREF is amazing and it’s now got 3 storms I’ve used it for nailed down inside 24 hrs. I think that’s something to monitor for down the road. I’ll be a little more cautious with these kinds of setups for now on. You live and learn. It was fun to track. Wish I could’ve been up during normal people hrs, but what can you do lol. 2 Link to comment Share on other sites More sharing options...

It APPEARS that storms want to keep taking a great path off the Carolina / VA coast to our SE. The pattern moving forward, especially from Christmas through January 10th, looks conducive for more of the same. Link to comment Share on other sites More sharing options...

Seemed like the far N/W zones mostly ended up with 7-10". Over the years that Miller’s report a couple miles east of me (they are about 200 feet lower) aligns with my snow depth at the end of storms better then snowfall. Sometimes the two are the same but sometimes when snow came in different parts with lots of mix and compacting they can be a bit off and their total almost always matches my depth.
