UWFPS 2017 daily cold-air pool forecast valid Sunday 2/10/2017 2:00  PM MST

A weak inversion episode will begin Sunday and continue until Thursday. Only 'modest' inversions are forecast given the lack of snow cover and increasing temperatures and solar insolation as we approach mid-February.  Pollution levels will likely peak on Wed and Thurs, but remain below the NAAQS standards all valleys (possible exception being Cache).

Another storm system will likely end the weak inversion episode on Friday 17 February.
