MN Transplant Posted December 17, 2020 2 minutes ago, MN Transplant said: The exact position of the surface low didn’t end up mattering as much as the upper air features. The 850 low, which is both broad and late developing, is basically over DC allowing the warm air to flood in. We always want an 850 track to the south of DC by a fair margin. By the way, look at the ridiculous lack of northerly wind barbs in this image. Southerly 850s in Erie! 1 1 Quote Share this post Link to post Share on other sites

psuhoffman Posted December 17, 2020 4 minutes ago, jayyy said: 850 low never closed off, allowing warm air to scream north. It’s early winter, barely below freezing, with relatively warm ocean waters compared to deep winter. If we had a closed 850 low south of here, this was an easy 12+ area wide Exactly...ERS caught this early on and no one wanted to hear it but he was 100% right. December coastal with super warm SST and no closed mid level circulation is a big problem...nothing to cut off the easterly fetch to the north of the low. This could have worked in 2 ways...true arctic airmass, phased system. In the end we got the perfect track...the blocking did its dirty work...but other parts didn't come together. December is a HARD month to get a BIG snow here. We are almost better off with progressive wave type systems that cant scorch the mid levels with screaming easterlies. December is a good month to waste a good pattern unfortunately. But give me this look again...anytime between xmas and March 10...and I will take my chances. 1 1 Quote Share this post Link to post Share on other sites

Don’t look now but there is a slight pivot to a more N/S Orientation on our radar, and snow is picking up here with occasional pingers mixed in. 1 Quote Share this post Link to post Share on other sites
osfan24 Posted December 17, 2020 Radar is definitely exploding but it looks like it's all advancing northeast rather quickly and the changeover line is lagging behind. 1 Quote Share this post Link to post Share on other sites

That road is a car trap any time we have frozen precip. Also: Am I the only one that is fine with sleet fests? Like, seeing sleet just filled my heart with joy after the last 3-4 hours of rain. Getting a lot of sleet seems to add some good staying power. One of my most memorable storms was... was it 2017? With the absolute epic sleet bomb 3.5" of sleet in Gaithersburg. Nope I like it if it’s between choosing sleet or zrain because zrain practically never lives up to the hype. Also, one of my favorite all time storms was Valentine’s Day 2007 when we got 7 inches of sleet and froze solid the next day day and didn’t melt for weeks.

But I am definitely up over 9 inches now for the event. I am not going to measure tonight. I'll do it in the morning. 1 Quote Share this post Link to post Share on other sites
poolz1 Posted December 17, 2020 Pouring snow similar to earlier in the day...radar looks to be eroding on the back edge fairly quick tho. We'll see if the lift N and eastward progress can slow like some of the mesos show. Quote Share this post Link to post Share on other sites

ErinInTheSky Posted December 17, 2020 I think I'm about to get my last chance for back end snow as this band moves in east from Frederick. Looking at reports though it's just more sleet. Quote Share this post Link to post Share on other sites

The back edge has slowed w of HGR, but it’s still moving NE a bit. Cue @psuhoffmanto tell us where the lagging ULL energy is to spark off some good banding if it shall come.

Cue @psuhoffmanto tell us where the lagging ULL energy is to spark off some good banding if it shall come. Certainly has transitioned to higher ratio type snow. Hard to tell because it is dark out but these rates right now might rival earlier today. Quote Share this post Link to post Share on other sites
