Cold with icy spots overnight. Heavy mountain snow all week

Winter Storm Watch in the Cascades starts Wednesday morning, another two feet of snow coming

PORTLAND, Ore — We’ve got cold air in place and with a clearing sky, temperatures are quickly dropping through the 30s. This may create icy spots on roads that remained wet after sunset.

A new storm spreads rain into Oregon Tuesday. The snow level will be low, but valley snow remains unlikely, other than perhaps a few wet snowflakes if the rain begins early enough.

Wednesday brings heavy valley rain, and heavy mountain snow.

There is a Winter Storm Watch in the Cascades from Wednesday morning until Thursday afternoon. The Cascades above 3,000 feet will see upwards of two feet of new snow over that time period. With more snow on the way later in the week.

The snow level will drop from 3,000 feet Wednesday to 1,000 feet Thursday. The valleys may see snow showers Thursday mixed with rain showers but sticking snow for the valley is unlikely this week.

I’ll be watching Friday closely, but again, it looks like sticking snow will stay in the hills above 500 to 1,000 feet and the valleys will just see a cold rain.

Stay warm and take good care of each other.
