8/30 – Rob’s “Final Friday of August” Morning Forecast
Surface high-pressure over Tennessee won’t move much over the next 36 hours as a weak tropical wave will traverse the central Gulf of Mexico this weekend. The wave is currently along the Florida Keys to the west edge of Cuba will work slowly westward through the weekend. Dry air should remain in place today/tonight. As the wave moves NW, moisture will gradually increase with precipitation chances returning to the Mississippi coast by late Saturday afternoon. Best chances for rain/thunderstorms will be late Saturday night through mid-afternoon Sunday as low continues westward.
Wild card is in the extended forecast…and the eventual track of Hurricane Dorian. The current forecast track has Dorian over central Florida Tuesday night, and only moving less than 5 mph at that point, so no local impacts through the holiday weekend. Beyond Tuesday, still a lot of spread in potential tracks and scenarios. No major changes to forecast at this time, but we suggest continuing to monitor trends through the holiday weekend until Dorian makes its northerly turn.
