  1. GFS verbatim is about 0.2" in DC. Reasonable.
  2. RGEM was a step back in precipitation compared to 18z. 0.3-0.4" in DC at the end of its run with light snow ongoing.
  3. HRDPS another slight step back. 12z 18z for the same period
  4. I think you misunderstood. I'm not saying the GFS specifically is the model with the least snow for DC - in fact I remember it having some monster outputs in the Jan 2016 blizzard. I'm saying that whatever model is most pessimistic - GFS, NAM, Euro, whatever - is the best bet.
  5. Going with the model showing the least snow for DC has worked out remarkably well for the past 2 or 3 years - that includes the Jan 2016 blizzard.
  6. I don't think 0.25" spread out over 12 hours would amount to 3". You can quibble all you want, but GFS is a nice reminder that this was and is a 2-4", despite what the RGEM and NAM want to do.
  7. Not accurate. Much better if you're south of Stafford county, but a downtick for most of the area. Verbatim, less than 0.3" at DCA.
  8. NAM 0.4-0.5" for immediate area at hr 42 and still snowing.
  9. If I get 2" I'll be very happy.
  10. Not sure how this is 2-4" for our area. Looks like 0-2.
  11. It has. I'm a couple hundred yards north of 66 in Arlington and the radar has worsened for me in the past 20 minutes.
  12. I agree that the 3K nam is a legit model... i was pointing out it wasn't a legit model that gave our area precipitation
  13. or... I have lurked the whole time watching the discussion and decided to pop in to correct an obvious falsehood (that the 3K nam is a "legit model" and showed precipitation for our area)
  14. The 3K NAM has a whopping 0.0" of precipitation for anywhere north of Woodbridge.
  15. 2.3" and moderate sleet in North Arlington.
  16. Wow, what a beautiful run for you guys. 12-16" of march powder.
