####018011481#### FNUS75 KSLC 130839 SMFSLC Smoke Management Forecast National Weather Service Salt Lake City Utah 233 AM MDT Tue May 13 2025......Warthen .DISCUSSION...An active pattern will more or less continue across Utah over the course of the next week. A strong cold front will continue to progress southeastward through Tuesday, with another deeper and stronger system favored to move through the region during the upcoming weekend. Given there does not appear much likelihood of any period of strong high pressure or ridging, day to day mixing heights and transport winds will support good ventilation and generally excellent afternoon clearing index values accordingly.
