DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
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. Gallina
