Like him or not, one of the greats of LR forecasting (yes Bastardi) often reminded us that a model run "must fit the pattern". That phrase has stuck w/ me for decades and makes a ton of sense.
That said....this run doesnt really fit.
NAO/AO solidly neg, w/ PNA still slightly neg (around that timestamp), would not show such ridging out west, and would be notably more supressed in the east, and likely wouldnt show a cutter.
Not parsing over details yet, cause at 252, the details are fuzzy at best, but thats a 10,000 ft view from my noggin.
