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.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
