Big changes are coming this week with our weather. The sunny, pleasant, comfortable and dry weather will give way to clouds, showers and mugginess midweek. Monday morning will be clear and cool with lows in the lower-50s. The day will be full of sunshine and highs will top out near 80. Tuesday we are expecting a mix of sun and clouds and although it will be dry, it will be warm in the lower-80s and muggy as well. Wednesday we will continue to thicken up the clouds, boost the humidity, and there will be a chance of showers developing in the afternoon. Rain chances increase Wednesday night into Thursday. Clouds hang on for Friday and clear Friday night. Temperatures will be in the 70s Wednesday through Friday and drop into the 60s for Saturday. Fall officially begins on Sunday the 22nd with the equinox time at 8:43 am.
