The heights here look slightly higher compared to 12z and check out near MN where the s/w is. That’s a little deeper too. So to me, that’s probably a north move from 12z.
The 850 temp comparisons can be noisy and a result of precipitation helping to evapo cool. 500 heights will show you if it’s amping or not. I can’t compare at the moment.
I know and I forgot about that, but this date was solidified awhile back anyways. I've been just all over the place. Looking forward to after Christmas when things settle. We'll get one going.
