A winter storm warning with heavy snow and cold temperatures remains in effect until 4 a.m. Monday for the area that includes Philomath and surrounding area, the National Weather Service reported.

Additional snow accumulations of 3 to 5 inches could be possible in Benton County.

“Snowfall amounts may greatly vary spatially due to the showery nature of the snow,” according to an NWS bulletin. “A much colder air mass will move southward from interior Canada tonight which, when combined with widespread showery precipitation streaming off the Pacific Ocean, will bring accumulating snow to all of western Oregon and southwest Washington. This will include elevations all the way to the valley floors and to sea level on the coast.”

The Sunday forecast shows snow continuing in the morning hours, giving way to lingering snow showers in the afternoon with an accumulation of 1 to 3 inches, a high of 36, overnight low of 23 and winds of 10 to 20 mph.

With the storm moving through, motorists should expect winter driving conditions with snow and ice-covered roads with reduced visibility.

“Anyone with travel plans should stay aware of the latest weather information, have alternative travel plans, or delay travel if possible,” the NWS reported. “If you must travel, slow down and allow plenty of extra time to reach your destination. Allow extra following distance to the vehicle in front of you and keep snow chains and a winter survival kit, including a flashlight, food and water in your vehicle in case of an emergency.”

Snow accumulation of up to 7 inches could be possible south of Eugene.

According to the NWS, “Snow will gradually decrease in coverage and intensity late tonight and Monday.”

Beyond the scope of the current winter storm warning, the forecast predicts snow showers picking up again at around 7 p.m. Monday and continuing into Tuesday. After overnight lows of 24 on Tuesday night and 21 on Wednesday night, the temperatures then begin to warm with rain showers likely later in the week. has no paywall and to keep it that way, we rely on voluntary memberships.
