  1. This trough feature extending from the main SLP is an interesting development that we've seen gain traction over the past 12-24 hours. It can enhance precip/snowfall. Folks in the Northeast see significant versions, Norlun troughs, that sort of do the same.
  2. 18z Euro with the bump NW. Wisconsin gets the goods. up into N-L. Michigan.
  3. I can make this happen. Though, further inland may be more interesting. .
  4. Ya'll are slacking... No 18z GGEM mention?
  5. have been fairly busy unfortunately. would like to have been posting more, but just haven't had the time.
  6. Cautiously optimistic would be the phrase I'd use.
  7. ricky's mind going a thousand miles a minute right now.
  8. that white rain is gonna stack nicely there.
  9. Ricky will tell you the same… Never add up the P+C amounts. .
  10. Overnight disturbance dusted the area… ORD - 0.4” MDW - 0.1” RFD - 0.5” .
  11. 6z guidance generally came in weaker/east for the most part, and slower developing. Weaker/drier/east is a trend you need not want to see in the Chicago metro/NE Illinois. Shall see if it was a one run blip, or if it actually turns into a trend. .
  12. That compact-potent disturbance moving through tonight is doing work out in Iowa. 1-3" reports in E Iowa, snow squall warning near DSM, and probably should have another in E Iowa. There was also a bit of TSSN earlier.
  13. Chicago/O'Hare received 0.93" of precipitation on January 9th, which broke the record precipitation total for the date of 0.76", which was set in 1946.
  14. Chicago/O'Hare received 0.93" of precipitation on January 9th, which broke the record precipitation total for the date of 0.76", which was set in 1946.
  15. Final storm snowfall totals…ORD - 3.2"MDW - 3.8"RFD - 3.9"
  16. They like to avoid that situation, because it is indeed a downgrade.
  17. Cook Co is split into 3 zones for headlines. Will Co has a similar split as well.
  18. A watch for downtown and near lake areas seems highly questionable at this point. At least for now...
  19. That's not quite how it works. Ratio's would still not be optimal, but you would improve pavement accumulation.
  20. Here’s a link to a limited amount of experimental output… https://rapidrefresh.noaa.gov/hrrr/HRRR/Welcome.cgi?dsKey=rrfs_na_3km_dev1_conus_jet&domain=full%3Ahrrr&run_time=10+Jan+2024+-+00Z Latest update that I saw was that after several delays, implementation was planned for end of 2024. The FV3 will also be part of things. Here’s a link the the experimental output from it… https://fim.noaa.gov/FV3new/ The whole system will eventually replace the HRRR, RAP, Hi-Res Window, and NAM’s. .
