Instability is lacking so still expecting only a few rumbles of thunder. The rain should continue through the evening and decrease late tonight. Behind the front northwest winds will help to bring temperatures down into the upper 40s to lower 50s. Strong cold air advection Monday will keep temperatures down. Will go on cold side of guidance with highs in the upper 50s to upper 60s...actually about 5 degrees below normal for this time of year. .LONG TERM...(Monday night through Saturday)... Will be in a quiet weather pattern throughout the extend with high pressure building in. This will result in mostly clear skies and dry conditions.
