Schools in Jefferson County are operating on normal schedules today, although some roadways may be slick from freezing temperatures overnight.

No snowfall hit lowland Jefferson County, unlike our neighbors along the northern coast of Clallam County. Port Angeles and Sequim schools are opening two hours late today. Snowfall has also created some school delays in Mason County and elsewhere.

Galley service on the ferry Kennewick is opening late due to contractors being delayed in reaching Port Townsend to board the ferry, Washington State Ferries reported.

The National Weather Service continues to adjust its forecast for the current mix of cold weather and precipitation. As of Monday evening, snowfall even at sea level is possible in Jefferson County. While snowfall along Clallam County's northern coast could reach 4 inches, less than 1 inch of accumulation is considered possible in the Port Townsend area.

Driving conditions may be sketchy Tuesday morning in East Jefferson County, depending on snowfall and below-freezing temperatures. School bus route schedules could also be affected.

MONDAY 9 a.m.

Snowfall in Brinnon Monday morning has not been enough of an issue to change the public school schedule. The National Weather Service has updated its forecast, with snow showers possible Monday night in lowland Jefferson County, and again Wednesday night into Thursday, before turning to rain.

No significant snowfall accumulation is expected this week in lowland Jefferson County.

The cold weather is expected to dip into the mid-20s this week in parts of Jefferson County, but no longer is the NWS calling for lows in the mid-teens.

SUNDAY 9:30 a.m.

While there is a chance of snowfall in lowland Jefferson County overnight Monday and again on Wednesday, it’s the cold temperatures that are really to be noticed.

The National Weather Service has issued a Winter Weather Advisory for much of the Greater Puget Sound area with an initial chance of snowfall possible from 4 a.m. to noon Monday, Dec. 5.

Snow accumulation of up to two inches is possible at an elevation as low as 500 feet.

Also, another burst of moisture mixed with cold temperatures is expected to raise the chance of lowland snow on Wednesday, Dec. 7, according to the NWS.

As of Sunday morning, the chance for snowfall is much greater in Jefferson County along Hood Canal, with an estimated 50 percent chance of snow overnight Monday in Quilcene and Brinnon. Snow is “likely” along the Hood Canal again on Wednesday into Thursday before the moisture turns into rain, according to the NWS.

The Port Townsend and Port Hadlock areas are not included in Monday’s snow watch zone but are included in the Wednesday snow forecast.

COLD SNAP

The NWS predicts low temperatures Tuesday night in the mid- to upper 20s in places like Port Hadlock and Port Townsend, but the low could be in the 14– to 17-degree range in places like Quilcene and Brinnon. Daytime highs throughout the week in East Jefferson are only to be in the mid- to upper 30s.

The season’s first cold snap means people should be aware of the needs of their pets and animals.

Motorists should be on the alert for slick driving conditions, with or without snow.

High daytime temperatures are to reach into the 40s again by Thursday.
