The para is just an outlier, IMO. It's not like it has support from other models anymore. It was abandoned by the parent GFS and the Ukie and it's trying to hold down the weenie fort all by its lonesome. I would weight it very low right now.
Huge discrepancies in QPF right now on EURO vs. other models... Not too sure about it tbh. Even the typically dry 3k NAM has about .2" more for the NW crew than the EURO.
Para is king of weenie town, other models converging on 2-4" for DCA, plus an inch of sleet or so. The sleet has a nice effect of moving overall totals closer together. Models with 4" snow have less sleet, CMC has 2" of sleet on top of that snow.
It is tough for some, yeah. These are all Kuchera (WxBell) when available, 10:1 when not. Sleet is not included, and if it were, the NAMs would be considerably higher.
