  1. Precip field actually shifted north on the GFS too. It's just farther south than other models like NAM and ICON. I'm not buying the 4-6" across northern neck and SoMD.
  2. First call: South of 66: 1-2” locally 3” Between 66 and 70: 2-4” North of 70: 4-7” Mountains: 5-10” Subject to change, hopefully with a last minute south trend. (But it COULD shift north)
  3. Is this where we say “uh oh” and root for a 4th last minute south trend? this is the ICON thread after all…
  4. Good run, but careful not to get any further amped else we'll either have temp issues or the best banding goes north of DC
  5. 0.5" qpf from harrisonburg through winchester through Loudoun and MoCo
  6. 850mb low just south of us, precip almost ending in DMV. Not longer duration, but maybe a heavier thump
  7. Heavier precip at 36, could be a longer duration than previous run Now I see an 850mb low
  8. SLP further back and 2mb stronger at 33 Big difference at 500mb. Previous run was flat and diffuse, now it's a bit more amped and further west
  9. 30-35% chance for 4” or more in dc/balt. I’d take those odds
  10. Looks on par with Jan 19 to me, if memory serves correctly. If this verifies or trends any bit wetter, we have a low end warning event. LWX may not go that far because its a saturday
  11. So far models are trending for the better. 36-42 hours out
  12. With the qpf and soundings you just posted, their snowfall output is probably wrong (again, it means nothing as far as verification)
  13. Ukie qpf actually looks about in line with the other models
  14. LWX has our low end being 1" and high end 5" in the dc/balt metros
  15. Looks south of what it was before, unless I got my wires crossed up with another model. Still think forum wide is good for 2-4" and northern tier get better ratios
  16. If that verifies, someone along the m/d line is getting 7”+
  17. Ironically, I think CC will do it. But who knows what will come next
  18. Not if the west pac warm pool and seas off Japan remain boiling. And a strong nina will just concentrate warm waters in the MC
  19. I’d want to see wholesale changes in the pacific and for those marine heatwaves to cease before thinking anyone east of the rockies get a snowy winter. At least the PDO has been less negative recently, but I’d want to see it firmly in positive territory.
  20. Its certainly possible. March waves tend to be crazy amplified but timing with cold air will be tricky esepcially this year. I’d be happy with one more chance to play in the snow with my daughter and call it a winter, though. That’s where my head’s at now
  21. Yep getting interesting. A little south trend won’t hurt. Wiggle room!
