Definitely a much stronger gradient than usual.  Hell, I have 6-7" more than BWI. 

And between you and me (close in DC burbs) it's a huge gradient.  I probably have about 6 inches on the season.

Got 5.5 but could have been more I’m teaching and couldn’t clear when sleet started to mix the last hour. Lot of compaction so the last band didn’t add any depth even though it was puking snow/sleet for 30 mins. But since I didn’t clear the area I can’t get a perfect measurement and I don’t want to guess and inflate so the final depth of 5.5 was what I recorded. It was very likely 6 had I done it correctly. 

I noticed you recorded 0.9 on 2/5. I have nothing recorded and no recollection.

Yes I can vouch for over on this side...about 10-11" but some of the heaviest snow of the year right now...go figure. Too bad it wont last.

It's very unusual.  I think largely due to the fact that the cities and 95 corridor didn't have 1 pure snowstorm this year.  Every single one has mixed.  If we had a uniform 4-7" storm once even, that would have smoothed some of these gradients.

I’m thinking only piles remain by the end of the week. Hope I’m wrong. It’s been a good run, whatever happens.

Probably. Not sure what your snow pack is. I was in PA yesterday and around York had way less then me. I have about 12-15” depth now and it’s THICK with about 5” of that being solid ice and likely 3” a qpf content. I also tend to hold “cooler” temps here. If it’s 50 in Westminster I’ll be 45. Maybe.

Yeah, this. Our only shot at a clean event was wave 2 of the Feb 10-12 timeframe, and that one completely clipped us. Final maps for the year will be pretty telling. Payback for Jan 11-13 2019 maybe? :yikes:

The last heavy burst changed to snow after it had been sleeting in Rosedale.   Now it's down to a light drizzle.

Probably have around 9-10 inches of snowpack, and it’s icy.

Our last overperformer.   

Also holds record for most forgotten bust by a model.    HRRR kept insisting on just a couple of flurries while we got another widespread 4-6".

Wow that's wild you have that much snow on the ground. I think I'm around 2 inches.

It fell between like 4-6am and melted on non snow surfaces by 8am. It was a quick thump band from the “cutter” kind of similar to today but MUCH weaker and not as cold.  It got really warm that afternoon.

I remember the NAM showing a medium sized event for most of the area up until 6z the day of, where it showed something like 6-10" with a jackpot near DC. I glanced at it before heading to bed pretty skeptical, but it doubled down on 12z with a jackpot of like 12-18". Wasn't as insane as that, but still a super memorable storm. The unicorn pattern long range models had been pushing might've not set up shortly after that event, but that still was a pretty decent winter for most. Surprised to see that McLean got 5.5" during that February. Even more surprising given that so far this month I've tallied 6.2", which takes the crown of most snow in February since at least Feb 2015 here. Also 4th snowiest month since I started keeping track starting in March of 2015 which is.. kind of just sad lol.

Yeah it's pretty crazy that the temp there can be significantly colder than Westminster, which is a pretty cold, snowy location compared to most areas around here.

Of course, it also helps that he tacked on almost 6 more inches today.

I'm expecting my snowpack will be gone by the end of tomorrow or Wednesday at the latest. All the ice and sleet might help it last until the end of Wednesday, but 50's and 60's this time of year with sun will melt it all real quick. Maybe keep my snowpiles through Friday? Probably should shovel what little slush is in my driveway onto those piles to keep them around as long as possible!

Think this has to have been one of the most difficult winters to predict preciptation types and the timing and amounts of each in quite sometime...Ive been following/studying/forecasting weather since about 2008 when I went to college for it. i cant remember a winter when the atmosphere has been so chatoic with the warm noses. We're a rate dependent area for sure...but the rates have really mattered this year in all the marginal events. Such a large gradient from PSU land to my land

Just made the trip back from Baltimore to frederick. 70 was a damn mess. Fascinating to see the different gradients of precip. Bmore was all sleet, around 29 it switched to snow and then on the warm backend in Frederick it was back to rain. Probably 6-8 people spun out in the median.

Measured 1.0 in Havre de Grace after the rain and sleet started so probs a bit more.

@Kay what did you get? We are usually within a few tenths lol.

1.5 just now, possibly more due to compaction.

Pretty incredible year up there for you. You usually do better than us out here. But not usually by this large of a margin. I am not complaining being over climo. Just making an observation. I have around 6 or 7 inches of snowpack. I expect it will be gone, except for the piles at the end of my driveway, by Friday.

Guidance being wayy too excited with precip hasn't helped either for sure. In some cases it hasn't been close. Most if not all guidance had 0.8-1" QPF with last Thursday's system from the DC metro up through your way, with a fair bit of it falling when the column should've been supportive of at least partly if not mostly snow (4-9am). Instead all that precip  with the initial impulse of snow went north of us, and I'm not sure either of our areas got even half as much QPF as most guidance showed.

You missed the Feb. 7th event? We got around 6.

I got 4 on the 7th. I think it was the 10th/11th event that made the biggest difference. I got an inch of slop while you guys got hit pretty well. 

3.5 here on 2/10-11 and 7.5 on the 18th/19th.
