The wildfires throughout Lake and Cook counties are continuing to produce
a large area of dense smoke that is now moving north into southern Ontario
towards Lake Nipigon.  Remnant smoke from this fire continues to cover
a larger portion of southern Wisconsin.  The smoke is just one of the
contributors to the overall smoke coverage throughout the central and
eastern US.

Great Plains into the Ohio and Tennessee Valleys:
Remnant smoke from the massive fire in the Southwest of the past few days
is seen covering southern South Dakota, Nebraska, Kansas and northeast
Oklahoma and extending east across southwest Iowa, Missouri and northern
Arkansas and into the Ohio valley and northern Tennessee Valley. The
smoke is mostly thin to moderately dense with the densest part of the
plume now appearing to be over portions of the Tennessee and Ohio Valleys.

The smoke mixes with a large area of haze that covers the southern states
from east Texas to South Carolina and Kentucky and Tennessee. It is quite
likely that some smoke is mixed in with this area but previous analysis
felt that haze was the primary constituent over most of this region and
the most recent analysis concurs with this assessment.  The area over
east Texas may be primarily smoke from a large fire in central Arkansas
that produced a large amount of smoke yesterday afternoon and evening and
continues to burn this evening. The fire is in Perry county and there
is an area of moderately dense to dense smoke that covers portions of
Perry and Garland counties.

California, Arizona and the Great Basin:
A large fire is burning in the Colorado River Valley near the border
of Imperial and La Paz counties.  A very dense smoke plume is seen
with this fire extending north/northwest into portions of southern San
Bernardino county.  A large fire appears to have developed over Lassen
county in northern California with a dense smoke plume fanning mostly
to the east into southeast Lassen county.   Any smoke from the fire over
Douglas county in western Nevada has mostly been obscured by approaching
weather system from the south.

A fire in northeast Valley county is producing a dense smoke plume
that extends 150 miles northeast into the southeast Montana county
of Jefferson.  Several fires continue to burn along mainly the western
half of Fort Peck Lake and are producing a moderately dense to at times
locally dense smoke plumes that has fanned out nearly 150 miles to the
southeast and covers the entire portion of southeast Montana.

Great Lakes:
The large fires in the arrowhead region of Minnesota in the Boundary
Waters Canoe Area of Cook and Lake counties have produced a long plume of
dense smoke that extends south from the fires across central Wisconsin
and then curves to the east across southern Lake Michigan and southern
Michigan and extends through southern and central New York into southern



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.
