We continue to see a very active Pacific pattern crossing the country and with colder air seeping into the Northern Tier, these systems have a very snowy side on their rear and severe side out ahead.

Simply skipping through the next 240 hours off the GFS alone, there is clearly a focus between Denver and Madison, WI for snowfall and I have counted up to 4 potential snow events from the central Rockies up through the Great Lakes.

Note the banana shaped position strengthening between 5-10 and 10-15. This will force and hold arctic air further south and with a still active Pacific storm track, we have plenty more snow to come over the Rockies and Plains as well as the Upper Midwest.

Note the warmth building over Alaska and Greenland while arctic air pushes south down the Plains.

If you take a look at the below GFS surface/precip charts that with each system crossing the Rockies, likely laying down additional snow on Denver, you get a shot of cold to follow. Each cold shot may be stronger than the last.

System 1 (now)

Note a nice warm surge out ahead. This fight creates a highly unstable atmosphere in between.

System 2 (weekend)

System 3 (Wednesday)

System 4 (late week)
