THROUGH 1545Z September 10, 2005

Mid-Atlantic and Midwest:
A large area of thin smoke from the previous week's fire output in Idaho
and Montana is caught in weak flow over the North Central portion of
the US into the Mid-Atlantic states.  Smoke can be seen in C Maryland
and C Virginia banked up along the eastern slops of the Appalachian
Mountains from NE of Winston-Salem, NC to Hagerstown, MD. This area
is connected to the main area in the Mississippi, Ohio and Tennessee
R. Valleys by a narrow strip across S WV near Beckley.  Within the river
valleys the smoke covers the SW one-third of Ohio including Dayton, the
Southern three-quarters of IN, all of Kentucky, Illinois, and Wisconsin,
as well as, the western half of Tennessee, extreme northern Mississippi,
NE Arkansas, the eastern half of Missouri (Columbia and east) and the SW
corner of Iowa.  The smoke is located in the mid levels and is currently
drifting under the influence of the High and weak NW flow descending
over the Central US ridge.


A pocket of moderately dense smoke covers most of the wooded areas of NW
Ontario and is bound by a line from N Lake Superior and Lake Nipigon to
the bend in the Manitoba/Ontario line NE to Hudson Bay then SE to the
Quebec line.  This area is more influenced by stronger westerlies over
the top of the Central North American ridge.


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.
