the Central/Southern High Plains and Central/Southern Rockies on Sunday...

...There is a Slight Risk (level 2/4) of excessive rainfall over parts of
Southeastern Florida on Sunday...

�Snow will develop over parts of the Northern Intermountain Region into
the Northern High Plains Monday into Tuesday�

An upper-level low over Southern California and the Southwest will weaken
and move northeastward to the Northern Plains by Tuesday. Moisture from
the Gulf will stream northwestward into the Southwest/Southern High
Plains, producing showers and thunderstorms with heavy rain. Therefore,
the WPC has issued a Slight Risk (level 2/4) of excessive rainfall with
these thunderstorms over parts of the Central/Southern High Plains and
Central/Southern Rockies on Sunday through Monday morning. The associated
heavy rain will create mainly localized areas of flash flooding, with
urban areas, roads, small streams, narrow canyons/gullies, and burn scars
the most vulnerable.

Also on Sunday, easterly flow off the Atlantic will produce showers and
thunderstorms with heavy rain over the eastern coast of Florida.
Therefore, the WPC has issued a Slight Risk (level 2/4) of excessive
rainfall from these thunderstorms over parts of the eastern coast of
Florida on Sunday through Monday morning. The associated heavy rain will
create mainly localized areas of flash flooding, with urban areas, roads,
small streams, and low-lying areas being the most vulnerable. In addition,
the easterly flow off the Atlantic will continue to produce showers and
thunderstorms over parts of the Southeast Coast and the east coast of
Florida through Tuesday.

Moreover, a front extending from the Upper Great Lakes southwestward to
the Southern High Plains will move eastward to off the Northeast Coast and
extend westward to the Northern Rockies by Tuesday. Rain will develop over
parts of the Upper Great Lakes into the Central Plains on Sunday.

Overnight Sunday, a low-pressure wave over the Central High Plains will
move northeastward into the Northern Plains/Upper Mississippi Valley by
Tuesday. Rain will develop over the Northern/Central Plains Sunday night
and move into the Northern Plains/Upper Mississippi Valley through Tuesday
morning. Snow will develop over parts of the Northern Plains late Sunday
night into late Monday night. Showers and thunderstorms will also move out
of the Central/Southern High Plains into the Plains by Tuesday.

In addition, a front will move onshore over the Pacific Northwest and
inland to the Northern High Plains by Tuesday. Rain will develop over the
Pacific Northwest and move inland to the Northern Intermountain Region
with snow at higher elevations Monday into Tuesday.
