Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 823 PM EST Tue Feb 7 2017 .FOR THE EVENING UPDATE... ...Severe thunderstorm watch in effect until midnight for Levy county... A strong U/L disturbance is moving across the southeast U.S. with an associated line of strong/severe thunderstorms currently approaching the big bend of Florida. 12Z TBW sounding quite unstable for early February with CAPE around 1800 with significant dry air aloft which will aid convective instability...leading to mid level evaporative cooling which will create favorable conditions for damaging downburst winds. The line of thunderstorms will approach the northern nature coast between 10 and 1030 PM with the potential for damaging wind gusts with the stronger storms across Levy county. The main U/L forcing will push across north Florida around midnight...and away from the region overnight. The line of storms will weaken rapidly as they sink slowly south across the nature coast after midnight...and will begin to dissipate as they approach the Tampa area. South to southwest boundary layer flow continues to advect very warm moist air over the coastal waters. Sea fog will likely develop late tonight over the eastern Gulf of Mexico which will advect locally onshore...with areas of dense fog possibly developing late tonight/early Wednesday morning across west central and southwest Florida. && .TBW WATCHES/WARNINGS/ADVISORIES...
