NWS Tampa Bay, FL wrote its last area forecast discussion before the first event at Aug 12, 1:04 PM EST, 3 hours 16 minutes earlier.
Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 204 PM EDT Wed Aug 12 2020 .DISCUSSION... High pressure at the surface and aloft stretches across Florida and into the Gulf of Mexico. This will allow for light winds across the region with a sea breeze developing each afternoon. Showers and storms are already firing up along the sea breeze and will continue through the early evening hours. There will be some minor fluctuations with the ridge axis location, but overall the synoptic pattern will remain the same through end of the week and into the weekend. The temps will run around average with daytime highs in the low 90's and overnight lows in the mid 70's. && .AVIATION... VFR conditions will prevail through the day. Showers and storms are starting to fire up, so will hold VCTS at all terminals between 18- 00Z. The west coast sea breeze has set up allowing for the winds to turn onshore. Winds will decrease to light and variable overnight. No other aviation impacts expected. && .MARINE... Benign boating conditions with light winds and minimal seas persist over the gulf waters. The primary hazard for mariners continues to be thunderstorms. A few coastal showers are possible in the early morning before storms really begin to develop inland during the day. Mariners should watch for storms that may develop and drift towards the coast during the late afternoon and evening hours, creating locally hazardous winds and seas. && .FIRE WEATHER... Scattered showers and isolated storms can be expected each day for the next week. These showers combined with high humidities each day will preclude any fire weather concerns. && .Preliminary Point Temps/PoPs...
