16. LESSONS LEARNED Dry slots associated with low pressure systems consist of clearer skies that allow surface temperatures to quickly rise during the day. Dry slots also coincide with no precipitation. Daylight savings time recently ended, which means the sun sets at an earlier local time. Maximum heating occurs at an earlier time (i.e. 18Z and 19Z). Clear skies and light winds at night allow temperatures to drop faster than models predict. Dew points typically reach their maximum around dawn (i.e. 12Z).

25. LESSONS LEARNED Clear skies and calm winds are ingredients for fall fog formation, but there needs to be recent precipitation and/or enough soil moisture. Also, calm winds do not produce enough energy to lift winds upslope for fog to form. Clear skies and calm winds will drop night temperatures below model output predictions. Airport elevation is around 3000ft. Models can be misleading in mountainous terrain because the grid points may be in different elevations. Mist does not always lead to low visibility and ceiling heights.
