...Unsettled weather across portions of the central Plains,
Tennessee Valley and along the Gulf Coast from Florida through
southern Texas, with locally heavy rain and isolated flash
flooding possible...

...Strong cold front to bring a notably colder airmass into the
north-central U.S. beginning late Tuesday into Wednesday...

...Hot weather remains across the western U.S. with the Pacific
Northwest carrying potential for record-breaking high
temperatures...

A stalled frontal boundary from Florida into southern Texas will
keep scattered showers and thunderstorms in the forecast for the
Gulf Coast region, especially Florida, over the next day or two.
Localized flash flood potential will remain across Texas through
early Tuesday morning but locally heavy rain will continue for the
Florida Peninsula into Wednesday.

Broad upper level troughing and weak disturbances in the flow
aloft will also keep areas of showers and thunderstorms across
portions of Nebraska, Kansas and Oklahoma through early Tuesday
while the threat for heavy rain shifts/expands into portions of
the Tennessee Valley. Any flash flooding is expected to be
localized to widely scattered but spotty 2 to 4 inch totals may
result in localized runoff.

Near to below average temperatures will linger for many east of
the Rockies through mid-week, but a strong cold front is forecast
to reach the north-central U.S. on Tuesday. Showers and
thunderstorms are expected with the front into the Upper
Mississippi Valley on Tuesday, expanding east and south along the
front for Wednesday. In the wake of the cold front, high
temperatures are only forecast to be in the 50s to 60s from the
Dakotas into northern Minnesota and Wisconsin on Wednesday,
roughly 15 to 25 degrees below early September averages.

Meanwhile, many locations west of the Rockies will remain hot over
the next couple of days, especially across the Pacific Northwest.
Extreme Heat Warnings and Heat Advisories are in effect for
portions of the Columbia Basin into northwestern Montana into
Wednesday. High temperatures may break 100 degrees for some folks
in northern Oregon and eastern Washington. Farther south,
monsoonal moisture will return across portions of the Southwest
and Four Corners over the next few days, bringing an increasing
chance for showers and thunderstorms.
