ARE WE SETTING THE STAGE FOR A NASTY THANKSGIVING WEATHER MAKER? MAYBE....ALL THINGS POINT TO A TRAIN OF WEATHER MAKERS STREAMING INTO THE NORTHWEST U.S. OVER THE 2 WEEKS....THIS SAID, IT FALLS DIRECTLY INTO LINE WITH TALKWEATHERS WINTER FORECAST. AREAS ALONG THE ENTIRE I-80 CORRIDOR IS LIKELY TO SEE THE FIRST REAL WINTER WEATHER OF THE SEASON - WITH HEAVY SNOWS ALONG THE CORRIDOR - AND SHOWSTOPPING WINTER MIX TO THE SOUTH.....JUST A HEADS=UP....

The nastiest travel weather in the nation into much of the week of Thanksgiving is taking aim at the Northwest.

A combination of a parade of moisture from the Pacific Ocean and the southward push of Arctic air will lead to some cold storms in the Northwest now through the first part of next week.

When the pattern finally settles, temperatures could dip well below zero in eastern Washington to Montana and the Dakotas, and snow could fall on Seattle.

Whether or not there are merely a few snowflakes or a bit more falling around Seattle remains to be seen this weekend. As does the possibility of temperatures staying below zero during the day over Montana early next week.

However, the worst travel conditions due to the weather will stretch from the coastal areas of Washington and Oregon through the northern Rockies and northern High Plains through at least Tuesday of next week.

Snow could clog the passes, while rain, fog and even wind-whipped snow could cause flight delays at some airports in the region.

Areas north of Interstate 80 can be adversely affected by the expanding cold and storms. Interstates 80 and 90 corridors appear to heading into the thick of the nastiest conditions.

As conditions may improve in the Northwest on the heaviest of travel days, next Wednesday, unsettled weather and travel problems spawned by advancing cold air may shift into the South, Midwest and finally East.
