High pressure builds in, dominates for several days... 

Yesterday's cold front will continue well south of the region today with any leftover AM clouds giving way to a mix of clouds and sun. Highs will be notably cooler today with the expectation of a low humidity day in the 70s as high pressure builds into the region. A mostly clear and cooler overnight period will follow with  lows in the upper 50s!

Mostly sunny and pleasant conditions are expected over the weekend with low humidity, and mostly clear skies follow each night. Another mostly sunny Monday with slightly warmer temperatures. then a mix of sun and clouds follows Tuesday. Humidity ticks up a bit Tuesday and Wednesday, and a frontal boundary off to our SE may be close enough to bring more clouds back into the picture midweek. Low pressure moving along that boundary should remain largely SE of the region Thursday, but we allowed for an isolated shower on the NW fringe.
