PM Update: Serendipitous September weather is on the way.
'You might call today Aug. 32, given the weather was pretty much exactly what we saw all month. Alas, weve turned the calendar corner into climatological fall, which covers the September-November period. Once we get northwest winds kicking tonight, that classic September weather is going to start filtering in. The next few day should be blissful.
Through Tonight: The heaviest of the showers and storms are out of here. We could see a couple more random showers this evening, through about sunset or a bit after. Despite the awful humidity of today, drier air is on our doorstep to the west and northwest. As we get through the late evening, well feel more of it coming in. Then the gates really open tonight. By morning, its mostly clear with refreshing temperatures of near 60 to the mid-60s.
Tomorrow (Thursday): Get ready for awesome. Its the kind of September weather we love to see tons of sun, lower humidity and temperatures reaching highs in the upper 70s. The main downside is a northwest breeze blowing around 15 mph, with gusts near 30 mph.'
