weekend...

...Severe weather expected from Central/Southern Plains to Middle/Lower
Mississippi Valley this weekend...

...Air Quality Alerts due to Canadian wildfire smoke remain in effect over

Shortwave energy stalled out over the Northern Plains will continue to
generate thunderstorms with embedded heavy rainfall across the Northern
Rockies/Plains through Saturday. A Moderate Risk of Excessive Rainfall
leading to Flash Flooding is in effect for portions of eastern Montana
tonight due to the potential for high rainfall rates over very saturated
soils. Meanwhile, severe thunderstorms will probably develop along a
shortwave and surface dryline over the Central/Southern Plains tonight. A
Slight Risk of Severe Thunderstorms is in effect for parts of southeast
Colorado, southwest Kansas and the Oklahoma Panhandle due to the
possiblity of large hail and severe outflow gusts. Upper-level energy over
the Pacific Northwest will support a Slight Risk of Excessive Rainfall
over portions of eastern Oregon and western Idaho, where high rain rates
and low flash flood guidance can lead to widely scattered instances of
flash flooding.

The threat for flash flooding shifts inot the Great Plains and Mississippi
Valley on Saturday due in part to the southward progression of a cold
front through the midesction of the country. Slight Risks of Excessive
Rainfall are in effect for portions of southeastern Montana, northeastern
Wyoming, western South Dakota/Nebraska,
