The stage will be set for Seattle and Portland to see their first snowflakes of the season in the wake of today's powerful storm.
Snow levels will be on the rise across the Pacific Northwest today as the potent storm swings onshore, allowing only rain to wet the Northwest's I-5 corridor.
However, the opposite will happen later this week as the storm's passage opens the door for bitterly cold air from Alaska and western Canada to plunge into the Northwest.
The cold is so extreme in Alaska that Fairbanks set a new record low overnight Tuesday when temperatures plummeted to 35 degrees below zero. Even colder temperatures are expected tonight.
It is not just the frigid air that will trigger snow in Seattle and Portland. Another storm must first arrive.
The snowflakes should return to Seattle Thursday night into Friday, then Portland Friday night into Saturday.
Between the two cities, the chance of snow is greater in Seattle than Portland.
Regardless, the snow will not amount to much in either city. Accumulations will likely be held to a dusting with slightly higher totals in the neighboring hills.
