  1. Probably the most significant and longest lasting that I can remember. .
  2. Freezing fog and low level snow showers here overnight and this morning. -DAB. .
  3. This event was C IL’s version of N IL’s day after Christmas 2009 surprise snowstorm. Both a product of a potent wave within the 500mb trough. .
  4. Looks like higher totals will translate into N IN as well, as banding is setting up as the UL disturbance pushes ENE. .
  5. Total precip bullseye up a max around 1.50” now. Even with a full half reduction, that’s over 7”. .
  6. Corridor between Champaign and Lincoln will end up with several inches. .
  7. this statement coming from you ironic. .
  8. And speaking of the system for tonight, most guidance bumped back north...with agreement on 1-2” for a good portion of the area. .
  9. Have been meaning to start a thread like this for the past few winters, but always end up forgetting... Just a little something for these systems, such as the one today/tomorrow, that don’t quite make it to being thread worthy... .
  10. Event 1... ORD: 2.6" snow/sleet. Here: 3.4" snow/sleet and ~0.20" ice. Event 2... ORD: 1.3" snow/sleet. Here: 1.3" snow/sleet and glaze of ice.
  11. Precip filling in now as the upper low passes to the south. Flipped to snow here about an hour ago, with a few tenths down. Should snow for several hours, with 1-4” area wide. .
  12. That was an error on their part from the start, in not having the WWA further NW. LOT had the same mistake in north having it far though N...and as did MKE. The consensus of guidance consistently had WWA level precip that far north. So for them to say the axis set up further north, is comical.
  13. Started as some sleet here earlier, before flipping to freezing rain. -FZRA continues with a glaze this far, and a temp of 32 now. .
  14. Location: 4 N QUINCY, IL Description: Ice Storm Magnitude: Report Time: 09:22 am CST - 1/1/2021 Remarks: PINE TREE BRANCHES FALLING OFF, LARGEST BEING 8IN DIAMETER. BRANCHES ARE BREAKING OFF FROM THE TRUNK .
  15. Large corridor across the SGF (Springfield MO), EAX (Kansas City) and LSX (St Louis) CWA’s ended up with 0.25-0.50”+ ice accrual. .
  16. Not to burst your bubble, but toss the NAM. Too far NE with event 1 and this current 2nd event, and already a far SE outlier for that 3rd event. .
  17. Comparing the 0z DVN sounding to the 0z RAP and 0z NAM for that location, they are running ~2C too warm at 925mb.
  18. To prove my point, these pictures below were just taken in Steward IL... .
  19. One thing to consider for portions of SE IA and N IL, is that many locations still have ice on trees (etc) from the first storm. Around here there’s still a solid glaze on trees, and I’d guarantee areas well to the W/SW that picked up 0.25-0.50” of ice definitely have more on the trees. Could lead to more sig issues overall out that way. .
  20. RAP and HRRR probably have the most sig overall solutions. .
  21. Might be the best overall combined snow and ice model run, but probably a bit overdone in both aspects. .
  22. he’s falling apart now that everyone else finally figured out his game. .
