The big news this week is COLD.
But before we get into the cold, a convergence zone will deliver 3-7 of new snow for the Summit and possibly Stevens overnight. Baker, Crystal and White will have less snowfall 1-3.
Cold artic air will flow into the NW as the week progresses. With clear skies and dry air, the nighttime temperatures will be frigid. This will be by far the coldest air of the season.
The weather will remain mainly dry, with an outside chance of a little light snow, but youll see sunshine with the cold.
Morning temperatures by mid and late week will be in the lower teens, single digits and below zero on the slopes. Shady spots will remain extremely cold all day. Even highs wont get higher than the teens in the Cascades.
There is uncertainty later in the week (Thu & Fri) with the amount and location of incoming precipitation. The cold air in place could mean a lot of snow in the lowlands (possibly Seattle and likely Portland) and in the mountains. Ill update as we become more certain. In the meantime, stay warm.
