A dominating high pressure system
will move in today which will give the northwest mostly sunny skies... But it won't last for long.
A low pressure system located just southeast of Alaska is on track to arrive in the contiguous states tomorrow. As a cold front that is associated with this
system passes through, heavier precipitation will coincide along with it.
It would not surprise me if the National
Weather Service issued a snow advisory in the higher elevations as this cold
front passes. As the cold front moves through northwest Washington, colder air
will usher in and lighter snowfall amounts are expected. In northeast Oregon, mountains may see 2-4
inches of snow Wednesday night and into Thursday. With the cities located closer to the
Pacific, Thursday looks to have a chance for some pop up thunderstorms. For higher elevations such as South Lake
Tahoe and northern California, windy conditions will take place Thursday with
snow showers along and behind the cold front. Snow accumulation for this area is
looking to be up to 12 inches at this time and light accumulations possible in
the valley floors.
…. Main message for the northwest U.S.: Be ready for much cooler temperatures to be settled in by the end of the
work week.
