More Snowfall 2-7-19

Light snow is possible in the mid-valley beginning late Thursday night and continuing Friday morning, with significant low-elevation snow possible Friday night and Saturday.

That's the word from the National Weather Service office in Portland which outlined the snow possibilities in a special weather statement issued at 5:51 a.m. Thursday.

Forecasters said a cold air mass will remain over the Pacific Northwest through the weekend, potentially lingering well into next week. This will result in additional chances for low elevation snowfall for northwest Oregon and southwest Washington, both along the coast and inland.

The next chance for low-elevation snow will be Thursday night into Friday morning, forecasters said, mainly across western Oregon. A band of light precipitation is expected to develop during this time, which will likely result in some snow flurries with little to no accumulation for many locations.

However, forecasters said, there are some indications that a steadier snow band may develop, which could result in anywhere from a dusting to up to one inch of snow on the ground by Friday morning. Temperatures will be cold enough for snow to stick to paved surfaces, so even a small amount of snow could cause travel issues during the Friday morning commute.

A more significant weather system will arrive Friday night and Saturday, forecasters said. Snow levels are expected to rise during the day Friday, with precipitation likely to fall as mainly rain below 1.000 feet through early Friday evening. However, snow levels will be lowering again Friday night, likely reaching the lowest elevations by Saturday morning. Heating of the day may allow general snow levels to rise a few hundred feet above sea level by early Saturday afternoon, but accumulating snow will still be possible down to the lowest elevations in any heavier showers.

Any wet or slushy roadways Saturday evening are expected to freeze quickly overnight, likely remaining frozen well into the day Sunday.
