  1. Quickly went from mixed precip, to snow pellets to full on SN with good flake size. .
  2. Mixed precip has commenced here. Locked and loaded for 10".
  3. I skimmed fairly quickly and didn’t see it mentioned, but 6z Euro bumped precip amounts as well... .
  4. Unless you mean the usual mix seen when saturation is first occurring, we’re not going to see a legitimate mix this far NE. .
  5. where's threat #2? mine didn't produce, yours needs to.
  6. 0z GEM a bit wetter across E IA/N IL, and many other areas to the S and SE.
  7. It's also wetter, with 1.40"+ precip at ORD. It did run a bit too wet with the last storm system, so chop a bit off and it's still respectable.
  8. The good news is that the ARW/NMM/NSSL WRF all are much wetter and snowier than the NAM/3KM NAM. Usually wouldn't mention them much in the winter, but might be of some use this go around.
  9. The NAM trending drier makes little sense looking at things. For example, PWATS are the highest on a NAM run yet, in excess of 0.80" up to DVN.
  10. 0z HRRR, obviously discounting the overdone LE. .
  11. 0z HRRR moves precip into some areas faster than other guidance, including Chicago metro. Has a dusting in some areas at 3PM.
  12. This storm system is not going to have the same sig/widespread convection further south, as the last storm system did. Also, moisture transport is great. PWATS were actually higher on 12z NAM than previous run as well. So no, there will be no moisture transport issues this time around. .
  13. 3km NAM is a crusher, with 6-10” falling in 6hrs at one point... .
