Chief Meteorologist Justin Stapleton‘s Daily Forecast Discussion:  

Conditions are starting to quiet down tonight as storm #2 finally winds down. The third and final storm will move through on Saturday with another round of snow for some, changing to freezing rain and eventually all rain.  So here’s the latest thinking/timing:

TONIGHT: Overnight, isolated freezing rain/snow showers will continue to move through mainly the central valley, with a few through the south valley. Temperatures have risen into the upper 20s but will fall a degree or two overnight. Roads are extremely slipper now and this will only add to the dangerous travel conditions. Icy roads will be the biggest concern. 

SAT: Warmer air moves in, bringing a chance for some wintry mix of sleet, freezing rain before changing to all rain later in the day for the S/C valley. Stays as all snow further north up towards Portland. However, with the snow on the ground, there’s a good chance it will slow the warming process, thus helping blast another round of freezing rain or ice in the south valley. Snow accumulations will likely be lower than Friday but still expect snow showers (1-3″) early Saturday, changing to freezing rain with light (< .25″) accumulations of ice. Finally warming enough to change back to rain in the evening. Biggest impact will be: Icy roads and possible downed trees or power lines.

SUN: All back to rain in most of the viewing area, still going to be tricky traveling north as Portland metro will be cold enough to still see snow.
