...Modest atmospheric river activity to bring multiple rounds of
beneficial precipitation across the Pacific Northwest and the Northern
Rockies this weekend into early next week...

...Large areas of the country will see much warmer temperatures over the
few days as Pacific air advances east across the Intermountain West and
out into the Great Plains and Midwest...

A series of low pressure systems advancing into western Canada will bring
modest atmospheric river activity into the Pacific Northwest this weekend
and early next week along with a series of frontal passages. The transport
of Pacific moisture ahead of these fronts along with onshore flow will
bring multiple rounds of moderate to heavy rain for the coastal ranges of
Washington, Oregon and northwest California, but with some potential for
locally heavy snowfall for the higher peaks of the Cascades. Some of this
precipitation is expected to spillover into the higher terrain of the
Northern Rockies as well. Given the ongoing drought conditions across the
Pacific Northwest, this precipitation is expected to be largely beneficial
as locally several inches of rain will be expected for the lower
elevations.

Farther south and east across the country, the story for the weekend and
into early next week will be mostly dry weather and moderating
temperatures. In fact, the influx of Pacific air across the Intermountain
West and downstream across the Great Plains and Midwest by Sunday and
Monday will allow for temperatures to surge well above normal. High
temperatures should gradually reach the 60s and 70s across many areas of
the Midwest and with some 80s expected farther south over the Southern
Plains. Milder temperatures will also be arriving across many areas of the
South and the East as temperatures here also advance above normal.

Despite much of the Central and Eastern U.S. being dry, some unsettled
weather may impact parts of southeast Florida this weekend, and especially
on Saturday, given close proximity of a front which will encourage a
threat of showers and potentially heavy rainfall. Also, increasing warm
air advection and moisture arriving ahead of low pressure crossing the
Northern Plains on Sunday will bring a threat of rain for portions of the
Great Lakes region.
