This blizzard is expected dump up to 14 inches of snow Wednesday which will make it the heaviest snowfall in this area in decades said the National Weather Service reports. Seattle was already hit by a snowstorm on Sunday.

A storm of possibly historic proportions is crashing into the Pacific Northwest. Seattle could see more than six inches of snow as reported on the weather channel as of 8:57 PM.

Since Sunday, snow showers have been falling off and on across the lower elevations of the Pacific Northwest. This wintry pattern will be capped off by a major, potentially historic, winter storm that will move across the region through Wednesday.

Major Winter Storm from Pacific Northwest to the Northern Rockies 

Late Tuesday night through Wednesday, a strong low-pressure system with copious amounts of moisture will approach the Northwest coast. This will set the stage for a major winter storm across the lower elevations and mountains of the Pacific Northwest. Travel could become dangerous or impossible in the cities listed below, just to name a few. 

Cities in the winter storm threat zone: Seattle | Olympia | Bellingham | Portland/Vancouver | 

Snow from this storm will spread well inland across the interior Northwest into the Northern Rockies. Spokane, Wash.Coeur d'Alene, IdahoKalispell, Mont. and Missoula, Mont. will all deal with substantial amounts of snow and rough travel conditions. 

How Much Snow? 

As usual, the big question is always: How much snow am I going to see??? Below is our snow forecast map for the Northwest region the next 48 hours. You can find specific snow forecast total ranges plotted below some of the cities on the graphic. As you can see, we are forecasting some rather hefty amounts across western Washington (including Seattle). 

One caveat to this forecast. There remains some uncertainty with how quickly the snow may eventually change to rain on Wednesday. This is particularly the case the farther south you go along the I-5 corridor (i.e. Portland/Vancouver). Snow should change to rain in Portland on Wednesday morning. 

Keep in mind, average annual snowfall is only 2.4" in Portland and 5.9" in Seattle, so these amounts are very significant for these metro areas! According to the National Weather Service in Seattle, Wash., snow amounts from this storm could exceed anything seen since November 1985 at Sea-Tac airport. 

More perspective: Seattle's snow history 

In the mountains (Cascades and Bitterroots), we expect several feet of snow to pile up!
