The fun thing about the 18z NAM is that it would probably bust on the other end. The banding is even north of @dendrite on that run, the watch areas could be too far south.
Yes and no. It is basically agnostic about the wind. Whether it feels like 30 below or actually is 30 below, cold is cold. The thresholds are dynamic based on climatology though.
Bingo. Caution flags.
It would be tougher for BOX, but we could go watches Saturday afternoon and upgrade on the midnight shift and be fine on lead time for a Sunday night into Monday event.
Actually it was pretty remarkable caution for our area. At least up here in New England we were citing all the uncertainty we've been talking about in here today.
It's definitely not a pure slider. The Q vectors show that the band is going to try and twist a bit.
So maybe more of a banana shape (there are meds for that) than arrow straight.
Max temp and Kuchera are the same. There are two equations, based on what the max temp in the profile is. And then Cobb05 and Cobb11 are just the years the study and the update were published I believe. So in theory 11 should be a bit better performance.
