Good Question, where is the Warm air aloft?

A good question from someone reading the blog, the current temps for government camp is 20 and its in the 20's at Timberline which is 6,000ft. I thought I saw some flakes earlier and I don't see why this couldn't start as snow. We may get some snow and it will then transition to freezing rain and sleet later. The moisture has reached salem but I have no clue to what is falling there because my weather spotters have not sent me info. I will be checking back, I wouldn't be surprized to see snow first, good possibility!
