High pressure centered over the region tonight will result in clear skies, diminishing winds and cold temperatures!  Most areas will drop into the upper teens and lower 20s, some of the coldest readings we've seen so far this season.  Despite the cold start Wednesday, sunshine and winds shifting out of the south will help warm us well into the 50s to near 60.  The warming trend will continue Thursday with many valley locations expected to rise into the mid 60s.
