In Portland's dry climate, a chilly Friday will present a brief lull ...

On Friday, cold and unrest forecasts for Portland but there are a few scattered showers, but it's also a very cool day.

Morning traffic cameras indicated clear skies as of 5 a.m., with early temperatures dropping below freezing in many locations. Snow levels remain low, but accumulating snow from any showers is expected to continue on Friday in outlying areas. Drivers outside urban centers should assume there will be slick spots early in this mornings commute, according to the weather service.

Any showers that are moving through will likely get carried out before noon. Skies might be partly sunny by the afternoon, and the high humidity should reach 53 degrees.

This morning, particularly west and south of the city, there's a lot of room. Take it out there and keep an eye on pedestrians and bikes.

Rain from south to north in the valleys and snow in the mountains and foothills will continue on Saturday morning. Portland might see a mix of rain and snow in the morning, as well as showers with thunder in the afternoon. Snow levels will remain between 1,000 and 2,000 feet much of the day, so showers that are rain on the valley floor could easily be all snow in the higher foothills. The daytime high is expected to reach only 50 degrees.

Snow will fall further into the Cascades, especially in the Lane and Linn county areas. A winter weather warning is in place for snow above 2,000 feet. Total new snow accumulations will range from 2 to 8 inches, with the southern Cascades getting the most trouble.

This Easter weekend, anyone cruising over the passes should be cautious of winter driving conditions, blowing and accumulating snow, and delays due to driven-out or collision vehicles. Snow showers should begin to taper off by the late afternoon.

Scattered mountain snow showers are expected today, and widespread snow will fall tonight and Saturday. The hardest accumulations will over eastern OR and far southern WA. Snow will fall off Sat night, and a dry and warm forecast is in place for Sun.

In most areas, high pressure building into the area will clear skies overnight and lead to a cold but dry early Easter Sunday. When the strong April sun rises, it should warm the atmosphere and increase daytime high temperatures to 59 degrees, close to what would be average in mid-April. Skies will be cloudy at times with possible sun breaks.

The dry period doesn't last long. Extended forecasts show another front moving in from the Pacific late Sunday, bringing rain and gusty winds to the valleys by Monday morning.
