Smoke & Valley Fog on Satellite - August 27, 2012

Smoke from wildfires in the western US and dense fog in the river valleys of the Upper Mississippi River Valley were both visible on satellite on the morning of Monday, August 27th, 2012.  Below is a visible satellite loop from 7am until 930am over the Upper Mississippi River Valley showing the smoke moving east across southern Minnesota and central Iowa along with the dense fog in regional river valleys.  Below is a picture from the NESDIS Hazardous Mapping System showing where the smoke originated from in the Rockies.  The red dots on the map show where the active fires are with many of them originating in northern Idaho.  The dense valley fog formed as a result of recent rainfall, clear skies and light winds overnight with visibilities dropping to a quarter of a mile or less at times.
