THROUGH 0100Z July 23, 2006.

An area of thin smoke in the mid levels has been moving slowly Seward
under influence from a northerly jet streak descending over the ridge.
So the smoke can be traced back to the boundary water fires along the
MN and Ontario, Canada boarders.  Currently the smoke is not more than
20 km wide between Lenawee county MI, across NW OH, to Grant county IN
where a bulge of smoke is about 75km wide from NW-SE and then thins back
to a 10km wide line across central IN to Shelby county IL.

An area of thin smoke has similar origins as the aforementioned plume
but was transported westward as the jet bifurcated the smoke area.
Now the smoke is barely drifting W and S across the Central 1/3rd of NE
and N 1/3 of KS.  The most dense area is concentrated over the central
Platte river near Kearney, NE.

N Texas:
A fire near Brock in Carter county OK produced a very thin plume of
smoke that has drifted SSW into N Texas and is now located over N Parker
county, TX.
A fire near Ogden in Baylor county TX is producing a very thin plume of
smoke that is moving SSW and extends to the Jones/Haskell/Throckmorton
county intersection.

The Jim Creek WFU Fire is producing a fan of dense to convectively dense
smoke between S and SSE (along the spine of the Wind River Mtns) and is
bounded by US-191 to the west and I-80 to the south in Sweetwater county.
The Magpie WFU Fire in Yellowstone Nat'l Park is producing dense smoke
that is moving SE and extends to near Eagle Peak just south of US
14/16/20. The plume is about 25km wide from SW to NE.
Smoke from the Little Venus and Bomber Basin fires has combine into
a larger plume that extends E to SE in a fan but is difficult to
distinguish between mid to upper level cirrus and stratocirrus clouds
but the smoke covers most of SE Park county, all of Hot Springs county
all of E Fremount and small sections of W Washakie county.

Thin smoke from the Quartz Creek and Elkhorn fires is merging into
a larger plume along the upstream tributaries of the Salmon river
and flowing NE into SW MT. Fields of low level cumulus clouds make
determination of the NEern extent of the plume difficult to determine
at this time.

A new fire in the northern extension of Emery county along the Carbon
and Sanpete county lines just south of Clear Creek, UT is producing
a towering plume of dense smoke that is moving SW crossing US-89 near
Mt. Pleasant and Spring City.

A new large fire near Rio Verde and Sunflower in Maricopa county is
producing moderately dense smoke that is currently moving WSW to I-17
near exit 223.

N Baja California:
A fire near Real del Castillo on the western flank of the Sierra de
Juarez is producing a moderately dense area of smoke that has mixed
with local thunderstorms and low level clouds.  The area is moving west
over the Pacific ocean and is expanding both N and Sward so that it is
affecting San Clemente island in the Gulf of Santa Catalina.

Northwest Territories:
A thin area of smoke covers the Eastern portion of Big Bear Lake from
fires burning west of the lake and east of the Mackenzie River. The
smoke is high in elevation and is most likely from last nights burning
in Canada along with some smoke from the fire in NE Alaska.



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.
