Clear skies and light winds tonight will allow temperatures to tumble into the 30s with patchy areas of frost likely.  Mostly areas will bottom out in the mid 30s, but some lower 30s are possible in the typically colder rural valleys.  Sunshine will mix with a few clouds on Thursday with afternoon temperatures into the mid 60s.  More clouds will arrive by Saturday morning with spotty showers possible as limited moisture approaches from the south.
