The first is around midday Friday, with colder air of Pacific origin behind it in NW flow (-8 to -12 C at 700-mb level). The second is associated with artic air spilling over the Rockies in British Columbia currently, which races southward through eastern WA/OR and arrives here late Friday evening (down to -16 C at 700 mb behind it). The third possible one is artic air that spills over the Continental Divide in MT/WY into eastern ID and then into northern Utah by Saturday morning (down to as cold as -20 C at 700mb). So looks very interesting as this system is mixing together air masses of very tropical and very arctic origin.Davidhttps://www.blogger.com/profile/02814313368731066590noreply@blogger.com
