####018011607#### FNUS75 KSLC 110949 SMFSLC Smoke Management Forecast National Weather Service Salt Lake City Utah 336 AM MDT Sun May 11 2025......forecaster .DISCUSSION...A large scale trough will approach the region into early next week as a stout ridge flattens and shifts east. Increasing deep layer south to southwesterly flow will result in excellent clearing index values and associated ventilation given strong transport winds and good mixing depth at area air sheds. A cold front will move through from late Monday evening to early Wednesday morning, but mixing height and transport winds are forecast to remain sufficient enough to yield continued excellent clearing index values across area air sheds.
