You did relatively well this winter considering, I basically lost interest after mid February without any type of upstream blocking or negative nao it was very difficult to cash in. I am looking for to a walk on Sunday morning when the temperatures are forecasted to be in the lower 20s , this might be the last time this winter we get to the lower to mid-20s for overnight lows.

I am totally content with this winter honestly. January was about as good as it can get here, so even though December was a snowless torch( the usual) and February was nearly snowless, I exceeded the the long term annual mean, and it all fell during the best month climatologically for combo of cold and snow and low sun angle. The pattern was generally cold and the snow stayed around awhile too. 5 Link to comment Share on other sites More sharing options...

Roger Smith Posted March 9, 2022 Share Posted March 9, 2022 Saturday snow potential in the I-95 corridor probably squalls with cold front that will blast through with NW winds 35-55 mph, could be brief visibility reductions with that, some areas a bit higher up will have a flash freeze situation and 1-2" then the mountains should see a decent snowstorm of 4-7". Morning highs will range from about 55-60 in the Delmarva and se VA, to near 45 in DC and 50 in BAL, temps will drop about 15-20 deg within 3-6 hours after the front. Hat tip to Capt Obvious on that one. Any last minute eastward shift on this low track and you have yourselves a surprise snowstorm. 5 Link to comment Share on other sites More sharing options...

At least that is what appeared to be when precip would be frozen. ETA: I'm talking more in the metro areas, but I'd still think most of it falls for the N/W folks in that same time period as well.

This is another event I log into my "this is concerning" mental file. Maybe not for DC and Baltimore as marginal events in mid March were always problematic for them, but up here this was troubling imo. We had a low off the Delmarva with a reasonable airmass profile across the CONUS to work with, at least by recent standards, and the lower levels didnt work out even for our area with 1000 ft of elevation. Even when it was pounding snow it was 34/35 degrees at my house! There have been numerous little things that bug me every time I see them. Like how there are frequently storms in mid winter without any appreciable frozen precipitation shield on the NW side at our latitude! Like how there are more and more examples of storms where there is no ice transition zone because the boundary temps are so warm well into the "cold sector" of the storm that it just goes right from rain to snow. We saw a troubling thing today that I have noted recently a lot...typically there are two zones of higher snowfall. One just NW of the rain/snow line where there is heavy precip associated with the frontal/baroclinic forcing and one further NW associated with higher ratios and better mid and upper level forcing. But lately the former zone is often rain...and the only snow zone is the latter because the rain snow line is much further NW then it should be given the track of the system and where the baroclinic boundary is! The retort I get every time I bring these things up is for people to focus on the imperfections. "Well this or that wasn't exactly perfect". Yea. That's true. I am not saying it can't snow anymore. But its not going to snow very much if we need EVERY DAMN THING to be exactly perfect. It used to snow frequently in very flawed scenarios. I know...I did a deep examination of every warning snowfall event for both our area and Baltimore! Not even the majority were perfect classic everything was right setups. All of the 20" plus storms were...and I would say most of the 10" plus ones in the cities are also...but up here we bootlegged our way to 10" storms quite a bit with really funky looking patterns and synoptic looks in the past.

It almost makes me think if something like Commutageddon (Jan. 2011) would even work out as well or at all in the cities anymore, if it were to occur today. It was a marginal event, at least near the surface. That may not be the best example, as that was very dynamically driven with intense uplift and I believe the 850 temps crashed. So perhaps not quite fair. But you get the idea. It was like 33-35, there about, while it was snowing hard for like 5 hours. A perfect paste job. Right after the snow ended it started melting underneath (at least on roads), before everything froze later that night as temperatures finally dropped.

I don’t have the ability to quantify this accurately. I’d be very interested if someone found a way to model this and went back and tried to use old saved data to project how some historical events would be different in todays temps. Of course maybe we could do that simply for the UHI effects but it’s not really likely to work on a full scale since the temp changes affect the global patterns so the truth is none of those storms would have even existed at all and completely different storms would if we changed the whole temp equation. You can’t just change just the temps but keep everything else the same. It doesn’t work that way. But to simplify I think everything’s bleeding the wrong way to some marginal degree. Ignoring the fact they wouldn’t be the same events I think in general storms that would have been a 30* 8” snow would be a 32* 6” wet paste bomb now. Some 6” paste bomb might be a 2-4” slush slop fest now. And what I was a slop fest is now white rain. You get the idea. Link to comment Share on other sites More sharing options...
WesternFringe Posted March 9, 2022 Share Posted March 9, 2022 Washington DC has annual snowfall data going back to 1888. When I get a chance, I will enter in all the annual totals and run a linear regression to find the line of best fit. By the slope of that line, we will be able to quantify any change in snowfall totals relative to the totals of the late 1880s, or from any point in time since for that matter. I can then overlay and/or add other cities and do likewise. It should be interesting to see how the cities may differ or not and what the slope is when starting with different points in time. 16 minutes ago, psuhoffman said: I don’t have the ability to quantify this accurately.

midatlanticweather Posted March 9, 2022 Share Posted March 9, 2022 I am definitely no meteorologist, but I wonder if there also a correlation to the heat of the ocean on the east coast. To me, when they are as anomalously warm as they are now it is a factor that can influence the impact of the marginal temps. Maybe I am grasping at straws.. but I just wonder.. yes, that can help juice up storms at times so it can be helpful, but I also think it messes things up. The Ocean is off the chart above normal!

There were several cold shots this past January that were certainly solid cold days but I'm convinced they would have been more impressive just several years ago. DCA is another story all together but now even BWI has trouble staying below freezing during the day even when there is a decent mid winter cold front. There are way too many days that bust warm now. A sunny winter day forecasted to be in the mid 40's ends up in the low 50's up here. On the other side it seems there are almost no days that bust too low anymore. 1 Link to comment Share on other sites More sharing options...

My take on today's event specifically is it was simply a bad setup for our latitude. The lower levels were complete crap with with really no mechanism for colder or drier air to advect in for any significant cooling. Most guidance had just about all locations wet bulbing above freezing. Dynamic cooling gets talked up a lot but it cant work miracles, and in this instance we would have needed some hella rates for a long duration to get it done even in areas with some elevation. Just because a low tracks along/off the coast to our south doesn't mean we snow simply because temps are marginal and "should cool" enough.

We can say that for a lot of events, but removing the weenie glasses this has mostly always looked too warm in front and too progressive, save for a few op runs here and there. Maybe the latest Euro is on to something (again?) lol. I doubt it. I think at best its a brief period of snow/ snow showers depending on the timing of the cold with the ass end of the wave along the front. We know how that usually works despite what guidance might suggest. Link to comment Share on other sites More sharing options...
