A.M. Clouds, Cool

A cold front that passed through early this morning brought a reinforcing shot of polar air to the region. This air mass is much warmer than the arctic air mass we dealt with late last week and this past weekend. Most people probably got a little spoiled by highs in the upper 40s yesterday, but we'll be several degrees cooler today. A few low clouds may pass through this morning, but the majority of the day should be sunny. Highs will top out around 43. Very weak warm air advection will commence tonight as an upper level ridge begins to build across the region from the west. However, mostly clear skies, dry air, and light winds will support a strong radiational cooling. Lows around 20 tonight will be the coldest we'll feel in the foreseeable future.
