000 FXUS62 KTBW 091145 AFDTBW Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 745 AM EDT Sun Aug 9 2020 .UPDATE... Coastal showers have once again shown up offshore this morning along the Nature Coast. However, these are quickly fading away now with the collapse of the land breeze. The rest of the morning should remain fairly quiet, with temperatures rapidly warming to typical summertime levels. The environmental setup today is very similar to yesterday. There are very light winds throughout the atmospheric column. This will again lead to erratic storm motion and outflow boundary propagation as storms begin to develop later on today. The initial source of convective activity should be confined to sea breeze boundaries, but boundary collisions will become more important later in the day. Once again, the thermodynamics do not support much in the way of severe weather. However, ample instability and a moist column will support storms producing locally heavy rains and frequent lightning. As is the case with any thunderstorm, they will still have to be monitored throughout the day as they can still produce gusty winds, and hail is not impossible if a storm grows tall enough. A few adjustments have been made to the POP grids to capture the showers offshore, and where they are fading away. Additionally, winds have been adjusted slightly to better capture sea breeze development. Otherwise, the forecast looks on track. A few more minor adjustments may be made, but no other major changes are anticipated before the afternoon. && .AVIATION... VFR conditions prevail with light winds under 10kts. A favorable environment exists this afternoon for thunderstorms to develop near airports again, much like yesterday. This could lead to periods of MVFR/IFR conditions, but this is too uncertain for mention at this time. Conditions will quiet again tonight. && .MARINE... Benign boating conditions continue under high pressure. While the bulk of storms are expected to remain onshore again today, mariners should keep an eye to the east for storms they may drift back towards coastal waters, particularly late this afternoon and into the evening. The otherwise light winds and seas may become locally hazardous with passing storms. && .Preliminary Point Temps/PoPs...
