The Big Chill The upper level pattern has amplified...a nice deep trof is now in place over the Eastern part of the US. That means some chilly temps for us....however....Today, the winds will still be coming out of the West and that means a little down slope warming. As the air comes down the Eastern side of the mountains, it compresses and warms. On Thursday, we loose that warming wind direction....so it should be in the 40s for afternoon highs. In addition, I think the winds will die down Tonight and set up for some good radiational cooling...lows will drop into the 20s for the first time this season in many places. Thursday & Friday will be the coldest days this week. It still looks like a little clipper system comes through on Friday, but it won't have much moisture to work with...so maybe just a few light showers or flurries.  ¶ 7:43 AM
