Snow to Snarl Travel, Expand in Northwest for Holiday Weekend

As snow winds down over the Central states during the weekend between Christmas and New Year's Day, a new storm will ramp up over the Northwest and will lead to travel disruptions.

The worst travel conditions during the latter part of the weekend will center on the Northwest as a storm moves inland over the area with lowering snow levels.

Poor travel conditions due to drenching rain, poor visibility and low cloud ceilings will extend from the central Gulf Coast to part of the mid-Atlantic on Sunday into Monday.

The balance of the nation will feature fair to good travel conditions. This includes areas from California to central Texas, northeastward to the Midwest and much of New England.

Good travel conditions are forecast for the Florida Peninsula northward to along the Georgia and South Carolina coasts.

Snow to Diminish in Central United States

The storm system that brought a general swath of 1-3 inches of snow from central Nebraska to the Upper Peninsula of Michigan during Friday night into Saturday will move off into central Ontario and west-central Quebec by Sunday.

A second swath of snow that developed in northwestern Texas and central Oklahoma early on Saturday morning will pencil out reaching parts of eastern Missouri and northern Illinois on Saturday night. However, enough snow will fall in this swath to make some roads slippery.

According to Meteorologist Brian Edwards, "As cold air invades the storm in the Northwest, snow levels will lower to around 1,000 feet in the Washington Cascades by Sunday morning."

Travel over Snoqualmie Pass along Interstate 90 will be difficult with a foot of snow forecast into Monday.

While mostly rain will fall along I-5 in Washington and Oregon, snowflakes can mix in to sea level in the Puget Sound area, including Seattle. There could be a coating of snow on some of the hills in the region by Monday morning, when some sunshine returns.

A foot of snow is possible over the Cascades in Washington, the Blue Mountains in northeastern Oregon, the Clearwater Mountains in Idaho and the Tetons in northwestern Wyoming this weekend.

Enough snow will fall along I-84 in eastern Oregon and Idaho, I-90 in Idaho and Montana and I-15 in Idaho and Montana to cause slippery travel and delays.

Snow will fall in Spokane, Washington; Pendleton, Oregon; Boise, Idaho; Billings, Salt Lake City and Jackson, Wyoming.

Spotty Snow to Struggle in Northeast

Rain affecting the South will become less intense as it streams into part of the Northeast Sunday into Monday.

In addition to producing wet roadways in the I-95 swath from Richmond, Virginia, to New York City swath, enough cold air can filter in to allow some wet snowflakes to mix in at times.

The odds are stacked against an accumulation, due to above-freezing air and road temperatures, as well as a lack of heavy precipitation. The push of colder, drier air into the Northeast will prevent a major storm.

As the storm affecting the Northwest eventually swings farther east, the latest indications are the atmosphere will warm up, bringing rain to most areas by next weekend.
