Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 835 PM EST Thu Jan 21 2021

DISCUSSION. A cold front is stalled across the northern FL border. This will settle southward through tomorrow, with the moisture allowing for some patchy to areas of fog overnight, and a few showers possible mainly across the northern half of the area Friday and Saturday. High pressure then builds from the NE then E through Monday, before the next cold front settles into the area and stalls through mid-week. Current forecast is on track with lows falling into the 50s. No changes planned.

AVIATION. VFR conditions expected through the early evening. Some patchy fog is then expected to bring some MVFR to possibly IFR conditions mainly 09-14z. VFR conditions then returns as the fog burns off, with light winds overnight, increasing from the SW late Friday morning through the afternoon.

MARINE. Winds and seas remain AOB 15 knots from the SW into Saturday. Winds then gradually shift around to the E by early Sunday as high pressure builds from the NE. Winds then continue to shift to the S through early next week as the high center shifts south over the Atlantic. Some low rain chances across the northern waters over the next couple of days, but otherwise no headlines expected 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.
