The 7z run knocked BDL down to 92 for today but gotta say...the NBM did quite well for yesterday's temps.
In the case of today, the only thing I can think of is there was a good bit of guidance perhaps slower with the cold front. I want to read more into what changes were made with NBMv5...I briefly did this a few weeks ago and there was mention this version was even more accurate with temperatures. I think the NBM may have a more "accurate" mixing capability versus traditional MOS and also isn't as scaled or tied into climo.
