One item I’ve been seeing from multiple sources is how the models’ cloud cover plots are not handling high-level cirrus well. The upper level RH plots indeed reveal a very different picture than the cloud cover plots. The 06z NAM for instance has high RH (presumably meaning cirrus of indeterminate thickness) over the entire northeastern US at 18z Monday.
The clearing that many models seem to agree on over the Midwest also includes a hole on the the 250mb RH. I’m not sure what to make of that as cirrus can presumably be thin enough or lower enough to not show well at 250mb.
This doesn’t do much for my already-shaky confidence levels.
