...Stormy weather continues across parts of the central Plains and along
the Gulf Coast through southern Texas, with locally heavy rain and flash
flooding possible...

...Cooler conditions persist across much of the eastern and central U.S.,
while a strong cold front brings a notably colder airmass into the
northern Plains and Midwest midweek...

...Heat intensifies in the Northwest, with record-breaking highs likely
across the northern Intermountain West...

Showers and thunderstorms will continue to develop this evening into the
overnight hours along and north of a slow-moving frontal boundary
stretching from the Gulf Coast back through southern Texas. With abundant
moisture in place, storms may produce heavy rainfall rates leading to
localized flooding, with isolated to scattered flash flooding possible.
Although unsettled conditions are expected to persist across Texas and the
Gulf Coast through tomorrow, the threat for heavy rainfall and flooding
should gradually diminish as the front shifts farther south and drier air
presses into the region.

Farther north, a slow-moving disturbance will trigger showers and storms
across portions of the central Plains, eastern Oklahoma, and the lower
Missouri Valley late today into tomorrow. Unsettled weather will linger
into early Tuesday before the system accelerates eastward, spreading
showers and thunderstorms across the lower Mississippi and Tennessee
Valleys by late in the day. In addition to the clouds and rain, daytime
temperatures will remain 10â€15 degrees below normal across parts of the
central Plains and lower Missouri Valley.

Across the eastern U.S., temperatures are forecast to remain seasonal to
below average into midweek. In contrast, above-normal warmth will persist
along the California coast and across the Northwest. Well-above-normal
temperatures will expand across the Northwest into midweek, with
record-breaking highs expected across parts of eastern Washington and
northern Idaho beginning Tuesday.

While the Northwest remains hot and dry, monsoon moisture will push
northward from the Southwest on Tuesday, bringing an increasing chance for
showers and thunderstorms across Nevada and interior California.

Finally, a strong cold front dropping south out of Canada will sweep into
the northern Plains and upper Midwest on Tuesday. This system will bring a
chance for showers and storms, followed by a notably colder airmass
spreading across the region.
