  1. 0.3-0.4” last hour. 5.3” storm total.
  2. Stopped briefly, but coming down really well right now.
  3. 0.9" last hour. 5" on the dot for storm total.
  4. Dumping with big flakes in Columbia
  5. First snowboard wipe. 4.1" official report, so 1.1" in the last 1.5 hours. Snowing well now with good size flakes. Still 24F.
  6. DCA with at least 5" per their ob
  7. Rt 50 corridor in MD between you and @MillvilleWx seems like the probable jackpot zone. Congrats dude.
  8. Guidance yesterday all had this window around 12z as the farthest north push of the warm air with greatest chance of mixing. It should retreat southward as the morning progresses.
  9. Was getting a little subsidence ahead of that band for the last 20 mins or so, but now both flake size and rates picking back up as it approaches. Should be a good next hour+ for HoCo. I was always skeptical of ratios much more than 10:1 with the WAA precipitation except for the far north folks. For dendrites, you want temps in the snow growth area aloft between -10 and -20C. And also aligned with the best vertical motion AND not overly strong horizontal winds. Didn't really look like that before this evening's snow.
  10. Seems I’m only allocated 5 reactions today. So imaginary likes and reactions to everyone!
  11. There’s a google form for official spotter reports
  12. Good morning everyone. Exactly 3” on the snowboard. 24F with mod to heavy snow. Small flakes.
  13. Radar will get a ring shape look to the echoes as virga overspreads the area. As the near surface layer moistens up, the ring will shrink and snow will reach the surface when it’s gone.
  14. LWX getting the half donut look. Full donut next and then no donut.
  15. Ravens v Steelers 8pm Saturday in Baltimore
  16. Blend the euro and gfs and it gives me 15-20” still. I can live with that.
  17. 30/7 let’s get this show on the road!
  18. My guess is if it played out exactly as the 3k NAM shows, areas near DC would mix in lighter precip right around 12z. Heavies would stay snow probably.
  19. 12z looks isothermal at 0C for a layer near 750mb. But colder before and after. Brief mixing if anything for DC proper.
  20. Thanks for the catch! Reading comprehension fail.
  21. 17z NWS map still has me in the jack. Fingers crossed. (stolen from @DarkSharkWX Twitter)
