0z GFS run...a run for the ages for next weekend

Well the models have been progging a trof in the Western US by late this coming week and have been advertising some serious cold air up in Canada to come on down into the northern plains with a strong wave developing and pushing northeast into the central plains bring up lots of moisture with it. And due to the extreme cold air entering the U.S from the north and alot of warm and moist air from the south, this is creating a serious baroclinic zone for this possible storm system to feed off of and track along. I won't get into serious details because its still 7 days out and lots can and probably will change in model land but some of these images are just insane..

H5 vort and winds showing the 120kt mid-level jet and very strong wave, the 80kt LLJ, 60 dews getting up into IA and northern IL and the 983mb sfc low in northwest IA.

It doesn't get more impressive than this for a system to produce both good severe weather and an impressive snowstorm on the cold side.
