With the unstable atmosphere causing a funnel cloud in Utah county on Monday, the sudden frosty weather, and snow in all elevations above 5000', you have to admit this is an incredible change from the summer. Not only that, there is another shot on Friday night at rain changing to snow in the mountains and windy cold weather for all of us Saturday morning like Thanksgiving, not September. Is it fall? It's more than that: It is the collapse of the Jet Stream even MORE than normal for this time of year.

As that river of air descends from Canada, it allows progressive systems to move through and shake things up. Some years, this happens more than others. This is one of those years in sharp contrast to the hottest summer on record when the Jet Steam took an even longer "vacation" from us than usual.

I'll be back with frequent "Jet Stream" updates.
