THROUGH 1615Z September 12, 2005

Great Lakes and Mississippi River Valley:
A large area of thin smoke could be seen over the Mississippi River valley
into the Great Lakes region. The smoke covers most of Missouri, Arkansas,
Illinois, Indiana, Michigan as well as portions of N Mississippi,
western and central Kentucky and Tennessee, and W Ohio. The most dense
areas appear to be over the upper and lower peninsulas of Michigan,
Lake Huron, and central Indiana. The smoke is trapped under a mid-level
ridge that is slowly progressing eastward.  Smoke is lingering under
the ridge from last week's fires in Idaho and Montana.

New England:
An area of thin smoke similar to the aforementioned are a is riding along
the NW flow downstream of the ridge across portions of New York and New
England into the Atlantic.  The core of the smoke area connects to the
Great Lakes plume across SE Ontario across Lake Ontario centered near
Watertown, NY and southeastward across Massachusetts into the Atlantic
Ocean centered off Cape Cod with an average N-S width of 200km. Smoke
moving S to SE along jet and originates from output from last week's
fires in Idaho and Montana.



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.
