Improving weather is coming, but it will take a little while to get here this weekend.
A frontal system will wash out along the South Coast tonight and Friday while high pressure tries to build in. The result will be mainly dry conditions, but still plenty of cloud cover, especially along the South Coast. Temperatures will remain on the cool side compared to the last few days thanks to northeast to east winds, but we should still see most places get into the 70s.
Meanwhile, an area of low pressure off the Carolina coast is trying to organize this afternoon and it could become a tropical depression or even a weak tropical storm over the next day or so. It will move northward and then northeastward, passing well south and east of us Friday night and Saturday. However, it will bring some gusty northeast winds to coastal areas, and churn up the seas again, resulting in some rough surf and rip currents at the beaches.
A weak cold front will also be moving in on Saturday, with a few showers possibly accompanying it. For later Saturday into Sunday and Monday, we’ll have high pressure building in, which means sunshine and mild temperatures, which is about as good as it gets for the final weekend of astronomical summer. Fall begins with the autumnal equinox at 3:20pm next Wednesday.
