THROUGH 1530Z September 11, 2005

Mid-Atlantic region to the Great Lakes region and middle/lower Mississippi

The large mass of smoke from active fires earlier this week in Idaho and
Montana has apparently become trapped in weak flow under a sprawling
ridge of high pressure over the Northern and Central portion of the
US extending eastward into the Mid-Atlantic states.  Morning visible
imagery shows the thickest density  smoke oriented from northern Louisiana
through Arkansas and eastern Missouri.  The smoke then becomes oriented
southwest to northeast and covers eastern Iowa/eastern Minnesota all of
Wisconsin/Illinois/Indiana and most of Michigan.  A much thinner area of
smoke extends from the above mentioned axis eastward through Kentucky
and Tennessee before it becomes nearly indistinguishable on satellite
imagery on the western banks of the Appalachians.

Ontario/Quebec Provinces of south central and southeast Canada:

The highest density smoke plume continues from Lake Superior and northern
Lake Huron and extends through the southeastern portion of Ontario and
into far southwest Quebec.  Clouds from weather system over southern
Hudson Bay have obscured any smoke that exists northeast of there.



Unless otherwise indicated:
  • Areas of smoke are analyzed using GOES-EAST and GOES-WEST Visible satellite imagery.
  • Only a general description of areas of smoke or significant smoke plumes will be analyzed.
  • A quantitative assessment of the density/amount of particulate or the vertical distribution is not included.
  • Widespread cloudiness may prevent the detection of smoke even from significant fires.
