This system will allow for good to excellent ventilation across most air sheds today with the exception of northwest Utah. Much cooler air behind this system will result in more stable conditions Friday with significantly limited ventilation. This stable airmass will remain in place through Saturday, with better mixing expected Sunday as southwesterly flow increases across the area.
