In South Florida, near record heat Thursday follows an October trend of above average warmth but also heralds a sweep of cooler, drier air that will last into early next week. A cold front, which was expected to bring scattered thunderstorms overnight and into Friday morning, is part of the same system that rocked eastern Texas and Louisiana with tornadoes on Wednesday but it was forecast to be more subdued by the time it reached South Florida. While high temperatures will remain in the mid-80s today (FRIDAY), they will be closer to 80 on Saturday and Sunday with noticeably cooler air as dewpoints drop from the upper 70s to lower 60s.
