Early evening clouds tonight will be quickly clearing after sunset. With dry air in place and lighter northerly winds, this will allow the temperatures to fall to rather cool readings for late April -- in the upper 40s to 50s. Abundant sunshine is expected Monday and Tuesday which will lead to warmer temperatures. However, the humidity levels will be rather low which will make for rather pleasant daytime conditions despite the very warm sun, and another cool night can be expected Monday night before warmer lows and higher humidity return Tuesday night through Wednesday. .
