Temperatures will remain slightly below normal through Monday, with one more cooler night in store as winds remain light coterminous with clear skies and high pressure influencing the region's weather.

We will continue to closely monitor the interaction of Tropical Storm Beta with a vorticity streak that rounds the basal side of an upper-level ridge axis that will persist across the area through mid-week. This may increase precipitation chances for the southern part of the area mid to late week, but for now, dry conditions look more likely to prevail with temperatures gradually warming to again be slightly above average by the end of the workweek. We even cross the 80-degree threshold again by next weekend.
Astronomical autumn officially arrives Tuesday morning as the center of the sun's disc crosses the celestial equator. The area will continue to see a loss of an average of several minutes of daylight per day.
