jayyy Posted December 11, 2023 Share Posted December 11, 2023 I was wondering about that too with much smaller amounts nearby, but maybe a lucky heavy burst? It's just curious though right on the water. Some good measurements in southern MD though, for example a couple inches in LaPlata (hi diatae!) Got 1.5 in Germantown which triples last winter's total MoCo schools delayed so my wife's preschool is closed. That's a gift since she's dealing with a bad cold and does not get paid on sick daysThey got that bay inlet effect snow. . 2 Link to comment Share on other sites More sharing options...

mattie g Posted December 11, 2023 Share Posted December 11, 2023 I honestly didn't measure here in Burke because by the time I woke up there had already been decent melting and compaction, but our cul-de-sac caved fully and was quite icy at about 7:00. Checked our Ring and you could just make out how our walkway caved at about 3:30 and then eventually melted. I was also shocked that the snow on cars and other surfaces was crusty and not just wet. I'm confident we had over 1" at the height of it. Crazy to think that we've bested last winter on December 11 with a post-deluge/post-front event. I guess that says more about last year than it does this year. 7 1 Link to comment Share on other sites More sharing options...

katabatic Posted December 11, 2023 Share Posted December 11, 2023 2.4" with a surprising (and not inconsequential) amount of -ZR this morning. There was enough so that even on paved surfaces that weren't treated, you were slipping and sliding. A pretty side effect was it encased the snow on the trees so even with a bit of a breeze, the scenery was still quite beautiful. 4 Link to comment Share on other sites More sharing options...

WxUSAF Posted December 11, 2023 Share Posted December 11, 2023 Ava Marie showed a picture from pre-dawn very near BWI that was clearly measurable.

stormy Posted December 11, 2023 Share Posted December 11, 2023 I usually review statistics on every event, winter and summer. A lot of discussion Saturday and Sunday concerned the preferred model measure of total accumulation. What I believed to be the common sense preferred measure because of marginal borderline surface conditions pre and during the event did not measure up very well in review. I usually relied on the Positive Snow Depth Change. In review, I found it to be consistently too low for both myself and Psu. Of course I realize it may have been correct for "skunked" locations. The 10:1 measure was far more accurate. 24 hours pre-event at 06 Sunday : Stormy 2.0" - Total PSDC - GFS .3" ECMWF 1.0" Stormy 2.0" - 10:1 Ratio - GFS 1.7" ECMWF 2.0" 24 hours pre-event at 06 Sunday : Psu 3.8" - Total PSDC - GFS .3" ECMWF 1.4" Psu 3.8" - 10:1 Ratio - GFS 3.9" ECMWF 2.9" Link to comment Share on other sites More sharing options...

IMO, this is part of a larger issue with the national AWOS/ASOS network. There has been extensive discussion in the New England subforum about the FAA's lack of routine maintenance for technology, and funding the observer positions at the airports. Thankfully, Maryland is deploying the mesonet statewide and we are adding snow depth sensors to all of our stations so this problem will be somewhat mitigated locally. 1 Link to comment Share on other sites More sharing options...

The nearest station that reported is right by South Run Rec Center and they reported 1.4". That also sounds like a good number prior to compaction and melting.
