...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.
