    18z GFS is pretty close to snow for morning commute based on soundings from the beltway west. https://www.pivotalweather.com/model.php?m=gfs&p=prateptype_cat&rh=2022122118&fh=18&r=us_state_de_md&pwplus=1&lon=-77.4364&lat=38.9752&metar=&st=b686ce5c32bed4c6

    Looking at the soundings on pivotal it would be a ~2 hr period of snow even for the immediate NW suburbs if 3K is right

    Having chased Lake Effect during college at Syracuse, stay off the Thruway or any interstate unless you wanna get stranded between exits. The towns will keep most primary and secondary roads passable enough even in crazy bands for pretty much any 4x4 but have a shovel in case you can’t find the road and get briefly stuck.

    Based on Twitter we had a possible touchdown in Tyson’s?

    W borderline temps I agree rooting for a bit of sleet early on will actually enhance accumulations by putting down a base to help overcome daylight and mid March

    Check the Whitetail webcams. Looks like a solid squall.

    Looks like the GL being a bit faster on the 18z is what screwed things up

    18z isn't a fan of Sunday

    If you want decent accumulation during the day w temps at/just below freezing a good rule of thumb is having visibility under a mile. Light Snow with .75 mile visibility and 32f will accumulate while light snow with 2 mile visibility and 30f will struggle to accumulate ~10-3pm.

    That band has been jumping around like crazy if you scrowl through the previous runs.

    While we are getting closer to the goods on the coastal, the front end stuff on Friday is a bit more ragged looking than past runs on both Nam and now NAM 3K which is in range. We need the front end stuff to score forum wide since relying on the coastal is a huge gamble.

    DCA has had as much snow as Albany this year to put things in perspective

    I’m thinking something similar to the 2/7/21 storm last year. Had a warm day prior and it was a bit slower to flip than modeled with inside the beltway underperforming a bit.

    The Euro on Pivotal is showing Sleet on the graphics but looking at the Euro soundings at 7 am it should either be Rain or Snow since there's no warm layer except at the surface. This may be why the snow map is lower than earlier.

    18z Euro isn’t a fan of Snow in DC
  16. rjvanals
    I approve of the NAM

    The low is 500 miles west of 12z last night. Definitely worth watching.

    If we hadn’t been chasing this for a week most would be happy. Also does show a signal for some wraparound snow on this run

    Low on the Euro is at least just east of DC this run; maybe some backside snow?
  20. rjvanals
    If you like snowpack you'd want some sleet with the Euro as progged since DC spikes into mid 40's as the Low passes over

    It's a unusual progression from the mouth of the Chesapeake to DC from 81-84
  22. rjvanals
    Goes over Chesapeake beach at 90
  23. rjvanals
    Better front end for DC at 87 L is just west of Richmond
  24. rjvanals
    I've thought the same thing for a while this reminds me of that storm. Maybe we do a bit better front end but that was still a fun strom.

    This run really torches us in the DC metro. Would still be a few fun hours Sunday evening.
