  1. Interestingly enough, the poorly performing 12z UKMET bumped NW and is now further N than the Euro.
  2. Neither of them are more accurate. A middle ground approach is always best when dealing with favorable ratios. .
  3. Indeed there are solid lapse rates shown and elevated cape correctly positioned as well. Another thing you like to see are high omega values, especially located within the snow growth zone for efficient snow production as well. There’s a nice overlap in this case. .
  4. Differences in the NW and SE solutions continues to revolve around the lead wave moving across Canada Tue/Wed and also a wave that stalls over the Northern Rockies and the eventual progression of it. All of the above is fully onshore and sampled. .
  5. Browsing through NAM soundings, and they are supportive of TSSN potential.
  6. Not really. They almost always mimic the previous NAM run. In this case the 18z NAM has bumped SE, so it was a given the 21z SREF would as well. Would expect the 3z SREF to bump back NW. .
  7. The former. Crusher. Edit: Both. Can see how it shears quicker heading into the Great Lakes.
  8. NAM will either be north, or end up going big earlier and shearing out faster.
  9. We’ll have to watch that trend. It was something that was seen with GHD3 in the days leading up to it. Guidance overcorrected in that case, and then ended up coming back faster once again. The other potential would obviously be for it to keep trending slower, which then could cause other issues .
  10. Ejection was a bit slower, which has been a trend.
