  • ...Dense fog this morning...
    .The combination of light winds, high moisture levels and wet
    ground has allowed patchy dense fog to develop east of the
    Mississippi. The dense fog is expected to become more widespread
    through sunrise before slowly dissipating through the morning
    commute. Although the dense fog is currently patchy, the
    possibility does exist of a rapid expansion around sunrise.
    ...DENSE FOG ADVISORY REMAINS IN EFFECT UNTIL 9 AM CDT THIS
    MORNING...
    * Visibilities...One quarter mile or less. The dense fog may
    quickly expand around sunrise.
    * Timing...through the morning commute.
    * Impacts...Low lying areas and river valleys are most at risk
    for seeing dense fog. Visibilities may change suddenly over
    very short distances.
