Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 904 AM EDT Sun Jul 12 2020

DISCUSSION. The front is already pushing into the Nature Coast this morning, and some drier air has already started to filter in there as a few showers stream across the southern zones. The front will continue to push south through the day, with the drier air continuing to filter south. This will keep rain chances low for the northern half of the area today, and also allow temps to climb into the mid 90s. Scattered to likely rain chances across the southern half of the area with highs in the lower 90s. Current forecast is on track and have no updates planned.

AVIATION. A few showers streaming in across the southern terminals this morning has allowed for tempo MVFR at those locations. W/SW winds will be in place through the period, with VCTS possible through the day for all but PIE and TPA where some drier air should keep them rain-free. VFR prevails, but MVFR to IFR conditions possible in storms.

MARINE. Westerly flow continues across the waters with more of a NW component across the northern waters behind the front. Winds are lighter today and the rip current risk has lowered from yesterday. Troughing will continue as the front continues to push south through the day. High pressure across Cuba then starts to build back to the north for early next week, with westerly flow continuing. Easterly flow then returns by Thursday as the ridge axis finally lifts north of the area. No headlines are expected through the period, but winds and seas will be locally higher near scattered thunderstorms. Current forecast is on track and have no major changes for the update.

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.
