    July Discobs 2019

    Cool pic right as I arrived at work just west of the WH. This is looking south just as the torrential rain started. You can see the obscured Washington Monument on the left.

    I have matched the speed of the wall the entire way from Clarksburg to almost to DC. It has been like being in a car wash the entire way. Surfs up!

    I drove down from my place up there last night. The rapid change in air mass in northeast Pennsylvania was like driving into a jar of Vaseline at speed.

    1.57 inches of rain in 14 minutes under 60dBZ returns in Clarksburg before I had to hop in the car to head to work. And still dumping… (edited to fit the return rate)

    Mid Atlantic Snow Totals Winter 2018-19

    Completely understand. Thanks for all you’ve done for the board previously, btw...

    @mappy Hi there. Did you do a map this year?

    April Discussion

    It’s been fun. I’ll miss the big whopper coastals that nail Parrs Ridge in central MD but really like the constant snowfall and snowcover here.

    I have to say, I’ve really enjoyed my first winter (largely) in Vermont. My place right now: 57620193611__1FC869E7-2E42-403E-B638-EAF00235E798.MOV

    March 22-23 Storm Thread: Cabins and Pony-Os?

    1.1" of snow this morning in Charlotte, VT, south of Burlington. Snow continues to fall but 2m temps are up to 35.1F so the snow is melting off of the trees and roads. Edited to add, I'm at 285' here in the Champlain Valley, btw.

    Grading Winter 2018-2019

    B. Grade is based on actual outcomes (fair number of events, actual total snowfall, good distribution throughout the season and decent snowcover longevity). If I weight the actuals with expectations as we entered the season, it would be a perception-biased C-. 10 year mean for MBY went from 34.34" to 34.42" 10 year median for MBY went from 22.5" to 28.8" There's very little chance both median and mean numbers don't take a big hit next year as the 87.0" from 2009/10 roll off the 10 year rolling averages next year. C'mon moderate El Nino + blocking............ Totals subject to change after the upcoming Sunday night snowshowers and midweek 1993 March superstorm redux. And the whopper on the 30th as well. :^P

    State of the snowpack in Clarksburg: I am not so sure that it is going to survive until next week’s big blizzard…
  14. Reanalysis is a part of the program so, yes. Next steps are to: "determine why some MJO events produce a response over North America while others do not. Preliminary results suggest that the convective anomaly near Hawaii might play an important role. This convection may be associated with anti-cyclonic wave breaking from the extratropics. Therefore, further research is required to determine whether the convection is driving the circulation or vice versa". So, still in the research domain but, there is very little meteorological research being done just for the sake of research anymore. The vast majority of it is focused on expressly enhancing predictive capabilities and mitigating impacts.
  15. Some of the experimental work to assess the impact of MJO on tangible North American weather is yielding interesting results. For example, typically, Phase 8 of the MJO is typically cold in the east DJF but, when the experimental Multivariate PNA (MVP) is negative, it actually trends warm. MVP is assessing OLR as a decent proxy for tropical convection in the MJO domains as well as streamwaves at 850 and 200 hPA in near real time . If you look at the MVP plot for the last 90 days, you can see it has indeed been negative during the time period we expected the best outcomes according to the ENSO and MJO forecasts. If y'all want to dig into MVP a bit, here's some decent reading.
