####018011369#### FNUS75 KSLC 041114 SMFSLC Smoke Management Forecast National Weather Service Salt Lake City Utah 504 AM MDT Sun May 4 2025......Cheng .DISCUSSION...A low pressure system moving slowly across the area will bring cooler wet weather through the first half of the week. This unsettled pattern will bring generally good to excellent mixing. However, cool and cloudy conditions will bring mixing heights down, and due to relatively weak flow near the low, transport winds will not be particularly strong, so clearing indices in some areas will at times be closer to 500 or perhaps even slightly below.
