...Light to moderate rain showers to continue over portions of the Pacific
Northwest...

...Lake effect snow showers continue across Great Lakes region over the
next couple of days...

...Warmer temperatures ahead for much of the country; Elevated Fire
Weather Risk for southern California...

A quieter and warmer pattern is ahead for much of the country as
upper-level energy remains either over Canada or stationary off the Baja
coast. A deepening low pressure system off the Northeast coast will cause
gusty winds across New England this afternoon through tonight. A weak
clipper system will bring another round of snow showers to the Great Lakes
region over the next two days. Snowfall totals will remain marginal, but
areas downwind of the Great Lakes may receive higher amounts due to lake
effect enhancement. A weak atmospheric river will impact much of British
Columbia, Canada and parts of the Pacific Northwest on Tuesday. Rainfall
amounts in the U.S. will be highest over areas that border British
Columbia such as the northern Cascades and Olympic mountains due to
orographic enhancement. Only a few inches of rain are expected to
accumulate over the area once the AR event ends on Tuesday night.

Persistent upper-level ridging and a cutoff low over Baja California will
contribute to warm air spreading across the CONUS over the next several
days. Temperatures are expected to be above average for much of the
country by midweek
