    Question why are they outliers when u have the GFSv16,GEM, RGEM , UKMET and both NAMS pretty much in agreement? They could all be wrong but please back up your statement.

    Lol, none of those models are as far west as the NAMs. The GEM/RGEM are somewhere in the middle, but the NAMs are, without a doubt, the furthest NW.

    I think the main source of uncertainty is over the the North Pacific.  It has good potential to trend NW if it comes off the Southern Rockies strong.  The pattern won't really be the same anymore over North America since the cold dome will be modifying some just because they days are getting longer.  Models just aren't sampling the source region for the upper jet streaks diving down the west coast very well.  It's not really an issue just affecting one model.  All of them have been sketchy lately at long range.

    Or any range for that matter.

     excellent under the hood discussion by the LOT forecaster. Even baked in the possibility of an over performance.

    I wouldn't be surprised if some of you who have continuously gotten snow this week do okay. I'm hoping for an inch. Have yet to see an inch from a single event this week, so it might be a fool's errand. Regardless, it's nice to have snow on the ground and I'm trying to just come to peace with the fact that that's as good as it's going to get this winter.

    First, confidence is increasing that a period of steady snow will
    occur Saturday as the diffluent right-entrance region of the upper-
    level jet stream passes overhead. Ensemble QPF from the ECMWF ranges
    from 0.10" along/south of I-80 to 0.25" along the IL/WI state line.
    A quick gander at forecast low-level thermodynamic profiles gives
    credence to very fluffy, perhaps "overperforming" snow ratios with
    the snowflake growth layer extending well beyond 10,000 feet at
    times. Plus, a trajectory off Lake Michigan may provide a boost of
    low-level moisture. Taken altogether, Saturday may end up yet
    another day to take it slow on the roads due to reduced visibility
    and accumulations of snow. The current forecast brings 1-2" snow
    totals from the Kankakee River Valley to I-88, and 2-3" totals from
    I-88 to the Wisconsin state line. Adjustments upward may be needed
    in later forecast packages.

    Is a LOT AFD worth reading if Ricky didn't write it?
