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

...Snow melt may lead to areal flooding across portions of the Pacific
Northwest, Northern Rockies and surrounding areas...

...Quiet weather for much of the CONUS this weekend...

Numerous locations along the Missouri and Mississippi Rivers, and their
tributaries, will continue to have major to historic flooding for at least
into early next week thanks to heavy rainfall earlier this week falling on
frozen ground and a deep snow pack that lead to intense and quick melting.
Flood warnings and advisories remain in effect, mainly across parts of the
eastern Nebraska, Iowa, and southern Wisconsin. Warmer temperatures this
weekend across much of the Northwest, Rockies and adjacent High Plains
will cause snow melt and runoff, which may lead to low-lying areas to
flood given that the ground is still frozen. Should ice jams occur during
this time, rivers and streams may rise quickly out of their banks.

Showers and thunderstorms will be likely across Florida each daily near a
lingering frontal boundary. Lake effect snow showers with mainly light
accumulations are possible across the Great Lakes. Elsewhere, surface high
pressure will dominate and keep calm conditions in the forecast.
Temperatures across much of the country look to be near or below normal
with the greatest departures expected across the Southern Plains where
afternoon highs could be 15 to 25 degrees below normal.
