The December 16th 1973 my mom talks about to this day . She was pregnant trying to get to the hospital to have my brother . She called it a blizzard ...said she barely made it Where was she living at the time. Westminster had 11” from that storm. I could see given the circumstances calling that a blizzard! January 2000 is a fond memory but not for the same reason as most. I was manning the weather station at PSU Hazleton the day before that storm hit. I remember looking at the vapor loop and comparing it to the guidance and it just wasn’t matching up. I Kept running the loop and thinking “why wouldn’t that just come up based on the flow”. I convinced my friend of such. I can’t remember the guys name, he replaced Jon Neese when he left psu, but me and my friend were driving the meteorologist who came in to check on the station crazy. He was dismissing it out of hand “No chance the models are that wrong at such short lead”. He didn’t even want to look at what we were trying to show him. Everyone else was focused on the long range progs for what would be the superbowl storm 5 days later. The next day we didn’t even have to say a word. We walked in and just looked at him and he said “I know don’t say it” 3 2 Link to comment Share on other sites More sharing options...

Heisy Posted December 9, 2020 Share Posted December 9, 2020 Maybe it’s the season of energy left behind? New England’s storm over the weekend originated from energy left behind that then rotated and phased. Usually when the euro is by itself for a run or two you usually see other models jump onto the idea, if not they usually cave, but you never know.... 1 Link to comment Share on other sites More sharing options...

H2O Posted December 9, 2020 Share Posted December 9, 2020 I know the argument over PAC vs ATL can be made almost every year and one bad side can overwhelm the one good side. But IMO in order to have ANY chances you need the AO/NAO to help be neutral/neg. I think that graph Wes showed many a time showed that its needed for snow in the MA. Obvi the PAC matters and both help with KUs but I'll take chances with a crap PAC and good Greenland blocking any day. 3 Link to comment Share on other sites More sharing options...

Obvi the PAC matters and both help with KUs but I'll take chances with a crap PAC and good Greenland blocking any day. Wes had a great CWG article on the phases/states of the indices wrt to DC snowfall years ago, with some scatter plots to illustrate. -AO has the highest correlation to above avg snow in DC, and when that occurs we almost always have a -NAO too. That being said, there are other ways to get there as we saw with favorable EPO/WPO in back to back winters several years ago, with little to no help from the the AO/NAO. That setup has a high risk of cutters for anything amped though. Ofc we also want ENSO to be warm neutral to moderate Nino in general for big snow in these parts. 1 Link to comment Share on other sites More sharing options...

That's a good plot...even the upper percentiles keep the AO near neutral or ever so slightly positive. I think @tombo82685 or @Rainshadow did some research and found that a -AO in December generally correlates to a -AO for most of the winter. 2 Link to comment Share on other sites More sharing options...

I watched it for a bit and then called all my plowing buddies by noon and told them to get ready for a surprise snowstorm. Called my parents in Richmond and told them to go to the store well before any forecasts had updated. Was a fun system to watch, but it was in a drier band in Eastern Loudoun so I only had 10 inches when further west had about 6 inches more and, well, it was so awesome up near Baltimore. Was a fun one to watch and enjoy! Link to comment Share on other sites More sharing options...

It’s a long shot but it’s the best chance we’ve had in a long time. Low bar lol. Doesn’t seem to be a lot of wiggle room. We need perfect spacing between systems. Ji was complaining we don’t even get fantasy storms to track anymore. At least he had one run to look at. 1 Link to comment Share on other sites More sharing options...
LP08 Posted December 9, 2020 Share Posted December 9, 2020 Standard shotgun of to far north, miss south, and hits. Definitely a signal for 7 days of at least a storm. Will come down to spacing. 2 Link to comment Share on other sites More sharing options...
WinterWxLuvr Posted December 9, 2020 Share Posted December 9, 2020 Laugh if you want but beware the model that’s in its own. It was one thing when this had support from the Canadian and the ICON but with them moving toward the gfs I’m skeptical. Link to comment Share on other sites More sharing options...

I started to take it as a really bad sign that climo is super hostile to snow down there now when it seemed like the models couldn't even bring themselves to show digital snow. We were just so far off from what was required to get a good snowstorm that model errors and biases couldn't even get it done. When I look at the GFS and Euro for MD now, it is such a dreadful snoozefest. 1 Link to comment Share on other sites More sharing options...

You can just come 25 miles west and see 20+. @psuhoffman Thanks for those setup maps. The thing I find interesting on them are the differences in the PAC. To me it really shows just how important Atlantic blocking is for us. Link to comment Share on other sites More sharing options...
