...Heavy rainfall possible along a lingering frontal boundary across
southern Florida...

...Major to historic river flooding will continue across parts of the
Mississippi and Missouri River Basins...

...Warm temperatures and snow melt may lead to areal flooding across
portions of the Northwest and Northern/Central Rockies...

The weather will continue to be fairly quiet across most of the lower 48
during the short range period. The exception to this will be across
southern Florida where locally heavy rainfall is possible along a
lingering frontal boundary Monday into Tuesday. Elsewhere, light rain or
snow is possible by Tuesday from parts of the central/southern Plains into
the mid-Mississippi Valley; and increased precipitation chances out West
by Wednesday as a cold front approaches California. Most locations from
the Rockies eastward will be dominated by surface high pressure which will
keep temperatures near or below normal for this time of the year. The
greatest departures from normal (10 to 20 degrees) are forecast across
parts of the southern Plains as well as the Appalachians into the East.

Major to historic river flooding is expected to continue across parts of
the Missouri and Mississippi River Basins due to rapid snow melt the past
few days. Flood warnings and advisories remain in effect, mainly across
eastern Nebraska and into parts of Iowa. Flooding is also a concern across
parts of the Northern Great Basin into the Northern/Central Rockies as
warmer than average temperatures lead to accelerated snow melt for the
lower elevations.
