...Heavy rain and mountain snows possible for parts of the Pacific
Northwest...

An unsettled pattern shaping up from Sunday to early next week across the
West. Persistent onshore flow will bring showers and higher elevation
snows to the Pacific Northwest on Sunday ahead of an approaching low
pressure center. The low will strengthen and eventually make its way
onshore in British Columbia on Monday with moderate to heavy precipitation
expected along the Coastal Range and Cascades. Some of the moisture will
find its way into the northern Rockies by Tuesday as a surface low tracks
inland. Temperatures will moderate across much of the Western U.S. ahead
of the deep upper trough offshore and will see temperatures rise above
normal across the central U.S. by the end of the period.

In the east, strong high pressure will momentarily give way to a weak
frontal wave moving from the Plains to the east coast with limited
precipitation. High pressure will regain control by Tuesday and although
temperatures will remain below normal they will not approach the winter
like temperatures experienced the previous few days.
