    Lingering low clouds will gradually lift as this storm system
    pulls to the East. New precipitation and clearing skies does bring
    some concern for valley fog. Neither guidance or short term
    soundings suggest fog developing at this point as drier air is
    moving. Overcast low clouds in the Vernal basin should also limit
    dense fog potential though MVFR fog may develop overnight. Will
    continue to monitor satellite and guidance data for trends and
    update as necessary. Otherwise VFR/ILS conditions should give way
    to all VFR by mid-day on Thursday with light winds in place
    through the period.
