A widespread wind event is going to slam Arizona starting Tuesday night and going into Wednesday.  This arctic blast will be due to a 150-mph upper-level jet stream moving over the region.  This will cause damage in many areas, including the metros.  Prescott stands a chance at having wind gusts over 70+ mph, or hurricane force.  Damage is sure to happen up there.

In addition to that, this will bring a round of mid/upper elevation snowfall through Wednesday, some of Thursday, with a break on Friday.  After Friday, a secondary system will move through over the weekend.
