A Special Weather Statement has been issued by the National Weather Service for icy roads in Northwest Oregon, including locally, this morning. And then, mixed Winter precipitation possible along the Central Coast late tonight and tomorrow. The coldest night so far this season has allowed temperatures to drop into the 20s for much of Southwest Washington and Northwest Oregon overnight. Enough moisture lingers near the ground that roads and sidewalks may become frosty or icy resulting in slick spots this morning. Secondary and untreated roads will be most susceptible to becoming icy. Use caution while driving; black ice can be difficult to spot at any speed, and can cause a vehicle to lose traction with little warning.
Additionally, a strong weather system will spread moisture over the existing cold air mass along the Central Coast late tonight and early tomorrow. Mixed precipitation of snow, sleet and freezing rain are possible. Amounts along the Central Coast will probably be light and brief before changing over to rain Thursday morning. Farther north along the coast, the low level cold air will last longer and some ice or even snow accumulations are possible through a good part of Thursday morning before changing to rain later in the day. Overall be prepared for slick roads early today and for some Winter weather along the coast tomorrow.
A Winter Storm Watch has been issued by the National Weather Service for significant Winter weather expected over Southwest Washington and Northwest Oregon (excluding the immediate coastline) late tonight and tomorrow. An unusually strong Winter storm will bring mixed precipitation across much of the area with significant impacts. This is the strongest storm of this type in quite a while. Snow accumulations of 1 or 4 inches are possible tonight, and ice accumulations of a tenth to a quarter inch are possible tomorrow morning (snow and ice accumulations highest in Portland Metro and the Columbia River Gorge). Travel will be difficult as some brief snow accumulations change to sleet and then freezing rain and roads become snow- and ice-covered and slick. A Winter Storm Watch means there is a potential for significant snow, sleet, or ice accumulations that may impact travel. Continue to monitor the latest forecasts.

Forecast: As is always the case with Winter weather on the Central Coast, calling it right is next to impossible. Everything depends on how long the cold air lingers and how fast the moisture comes in off the ocean. Sometimes the warming is fast enough that we don’t see anything but rain, while on other occasions we’ve had several inches of snow topped by a coating of ice. As of this morning, the best guess is kind of a cop-out with a 50-50 coin-flip chance of some light snow, sleet and/or freezing rain tonight after a day of increasing clouds and a high around 40F. Tonight’s low is expected to be right at freezing. Tomorrow, warm rain takes control, a southerly wind ramps-up to 30 mph or better and the mercury climbs to 50F. Outlook is for showers Friday through Tuesday with seasonal temperatures; highs of 45-50F and lows of 35-40F.
Travel: With temperatures at or below freezing early today, black ice and frost are possible on all Central Coast roads, so heads-up while driving locally. In the Coast Range this morning, there’s roadside snow, areas of icy pavement, and 25-30F in the passes; patchy freezing fog, partly cloudy and windy today, high temperature 35-40F. Willamette Valley destinations are expecting areas of fog early, sunshine later, the thermometer rising to 35F. The Columbia River Gorge forecast calls for mostly cloudy skies, east winds 15-25 mph gusting 35 or more, high of 30F. For the Cascades, highways are snow-covered this morning, temps are about 15F, chains or traction tires are required in most areas near the passes; mostly sunny and breezy today, the free air freezing level is at the surface. NOTE: Travel conditions are predicted to become hazardous throughout Northwest Oregon tonight and Thursday with snow, sleet and freezing rain. * Motorists should always visit ODOT’s TripCheck before hitting the road.
Marine: E winds blowing 15-25 knots this morning are pushing seas down to just 7 feet at 11 seconds. A Small Craft Advisory for winds is in effect from this morning through tomorrow morning. A Gale Watch is in effect for tomorrow morning through late tomorrow night. E winds 15-20 knots gusting 25 today, swells subsiding to 5 feet at 10 seconds. Tonight, the E wind rises to 20-25 knots gusting 30, swells dip to 4 feet, and there’s a chance of light freezing rain after midnight. SE winds are on tap tomorrow, 25-30 knots gusting 35-40, veering to S in the afternoon, combined seas building to 14 feet at 13 seconds with freezing rain possible before noon. Outlook is for SW winds 25-30 knots gusting 35-40 on Friday, combined seas 21 feet, W winds 20-25 knots Saturday, swells subsiding to 14 feet, and then S winds 15-20 knots and 7-foot swells on Sunday. * Make sure you check the latest Bar Reports before venturing offshore.
