Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 412 AM EDT Wed Apr 8 2020

DISCUSSION. Westerly flow will be in place through Thursday with high pressure ridging across south Florida. A boundary will settle through the area Friday with some upper shortwave energy allowing for a few thunderstorms. The boundary shifts back to the north for the weekend, with low rain chances remaining across the Nature Coast. A cold front is then expected to stall across the area Monday, with a series of upper shortwaves moving over the state through Tuesday. This will keep a chance for showers and storms across the area through the end of the period. Highs generally in the 80s, except cooler Friday. Lows will be in the 60s to mid 70s, except lower 50s to mid 60s Friday night.

AVIATION. Westerly flow will be in place through the day with wind speeds increasing through the afternoon, then diminishing after sunset. Some patchy fog this morning may cause brief MVFR to IFR conditions, but VFR is expected across the terminals from 14z through the rest of the period.

MARINE. Westerly flow will be in place across the waters through Thursday. A boundary will then move through the waters Friday, with some showers and storms possible along with winds turning to the north. Winds continue to veer to the SE for the weekend. A cold front will then stall across the waters for early next week, with showers and storms again possible. Winds increase Sunday to near advisory levels, so will be monitoring that, but no other headlines currently expected.

FIRE WEATHER. Afternoon humidities will remain above critical levels through the period.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
