Valid 081200Z - 091200Z

...NO CRITICAL AREAS...

...Western U.S....
An upper-level trough moving into the Pacific Northwest and
resultant increasing southwest winds aloft across the western U.S.
will promote breezy southwest winds of 15-25 mph across portions of
Upper Colorado River Plateau, Great Basin and northeastern
CA/south-central OR Wednesday. A well-mixed and dry boundary layer
will support minimum relative humidity values in the 15-20% range
with some localized values around 10%. However, fuels remain largely
unsupportive of significant wildfire spread with expected ERC values
largely at or below the 60th percentile across the region.

...Northern Plains...
An increase in southerly return flow across the Northern Plains as
surface high pressure moves into the Great Lakes is expected
Wednesday. A residual dry, post-frontal air mass across the Upper
Midwest will be in place but stronger south winds should be
displaced to the west of where RH values of 20-25% are expected,
limiting fire weather concerns across western MN and eastern ND
Wednesday.

...Synopsis...
Upper ridging will dominate much of the central U.S. as a mid-level
trough ejects into the Atlantic and another trough amplifies over
the Interior West tomorrow (Wednesday). Surface high pressure will
overspread the CONUS east of the Mississippi River while surface lee
troughing develops over the northern Plains, and a surface low
strengthens over the Pacific Northwest. Dry and occasionally breezy
conditions may develop over the Interior West, though fuels that are
poorly receptive to wildfire spread will limit wildfire-growth
potential. Across the northern Plains, the lack of lower RH will
limit wildfire-spread potential in this area as well. As such,
overall quiescent fire weather conditions are expected over the
CONUS for Wednesday.
