PORTLAND-- Morning commuters should expect a 'wintry mix' of precipitation on Friday according to a National Weather Service special statement issued Thursday.
The mixture of snow and freezing rain or sleet is headed for the northern Willamette Valley and Southwest Washington in the morning and should give way to rain by the afternoon and evening.
KGW Meteorologist Matt Zaffino said there's a chance that some part of the region could escape cold temperatures.
"There's a possibility that some areas will see temperatures around or just below freezing," Zaffino said. "That means we may see a brief period, from say 3 a.m. to 8 a.m., of light snow or freezing rain and sleet."
Temperatures should rise quickly by late morning or early afternoon. Two to four inches of snow can be expected in the southern Washington Cascades before precipitation turns to rain.
The National Weather Services anticipates a difficult commute Friday.
