  1. Differences in the 12z NAM start off at noise level early in the run, but increased quickly by mid-run. Main storm is definitely jumping north on this run.
  2. A lot of guidance that is south of the GFS are still showing significant snowfall totals. I’m not saying it’ll be the case with this one, but there are many cases that would prove the first part of your comment wrong. .
  3. 0z GEM appears to have bumped north with both the overrunning and main storm.
  4. Some of the positives we saw, such as with the 12z run, stepped back. PV in Canada was further SW, along with associated area of confluence. Heights also steadily lower ahead of the main ejecting wave.
  5. you had to pay for the derecho years prior.
  6. Looks like 0z GFS will bump south with at least the overrunning portion. Edit: And likely main storm too.
  7. COOP observer and NWS OBS sites are more the official route. CoCoRaHs is supplemental.
  8. There were only ~3 EPS members that had the main storm this far north.
  9. It does, but the 18z EPS goes out to 144hrs.
  10. Cross referencing COD, looks the same as WxBell… .
  11. Would hope that we have the overrunning portion sorted out by tomorrow at some point, and the main storm on Monday hopefully.
  12. It has been exceptionally bad this season.
  13. Fairly large changes on the 18z GFS.
  14. well, that’s a wrap for here. .
  15. The latter one is the correct one in this case. .
