Slight Risk of excessive rainfall over parts of southeastern Florida

...Wet snow develops over parts of the northern Rockies and the northern
High Plains Monday and Tuesday...

An amplified weather pattern featuring an upper-level low sliding across
the Four Corners against a strong ridge of high pressure anchoring across
the South will maintain a stream of subtropical moisture from Mexico into
the southern Rockies and southern High Plains. Under this pattern, this
moisture plume will shift very slowly eastward over the next couple of
days. The most active showers and some embedded thunderstorms are found
across the south-central High Plains south of a stationary front this
Sunday afternoon. WPC maintains a slight risk of excessive rainfall
through tonight for much of the southern High Plains where additional
heavy rain could form ahead of a trough of low pressure. From Sunday night
into Monday, a low-pressure wave is expected to develop over the central
High Plains and move northeast toward the northern Plains. A swath of rain
ahead of the low-pressure wave will gradually overspread the northern
Plains, bringing 1 to locally 2 inches of soaking rain area-wide and into
the upper Midwest by Monday evening. The low-pressure wave will also drag
colder air from the north, which could change the rain to wet snow across
the higher elevations of the central and northern Rockies into tonight, as
well as across western South Dakota into central North Dakota on Monday.

Meanwhile, persistent easterly flow on the south side of a large and
strong high-pressure system under the slow-moving weather pattern will
continue to feed Atlantic moisture toward the Sunshine State. This will
maintain a threat of heavy rainfall for the east coast of the Florida
Peninsula. WPC highlights a slight risk of excessive rainfall for
southeastern Florida through tonight, lowering to a marginal risk for
Monday and Tuesday.

Across the Pacific Northwest, a low-pressure system is edging gradually
onshore. This system will bring a round of rain area-wide through tonight,
possibly with a few embedded thunderstorms. The rain is expected to
penetrate further inland across Oregon, reaching into Idaho on Monday. By
Monday night into Tuesday morning, high-elevation snow is forecast for the
northern Rockies before the snow lightens during the day as the system
exits into the northern High Plains.

Elsewhere, under the amplified and slow-moving weather pattern, cooler
than normal temperatures are expected to prevail along the East Coast and
down into portions of the Gulf Coast states through tonight before a
warming trend sets in on Monday. In contrast, return flow from the south
will bring much above-normal temperatures well into the 70s and lower 80s
from the central and southern Plains across the Midwest and Ohio Valley
through the next couple of days. Meanwhile, dry weather will prevail
across the Southwest. Colder than normal temperatures will overspread the
Pacific Northwest into the northern Rockies behind the low pressure system.
