Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 121 AM EDT Fri Apr 3 2020

AVIATION. VFR will prevail during the next 24 hours with an increase in high clouds aoa 150. Northeast to east winds in the 5 to 10 knot range will prevail, except becoming onshore at the coastal sites after 18Z with the sea breeze component. Light and variable winds will return after 01Z tonight.

Prev Discussion. /issued 740 PM EDT Thu Apr 2 2020/

UPDATE . Dry and benign weather continues across the area with clear skies and another pleasant, cool evening. Morning lows will bottom out in the 50s area wide with a few isolated spots in Levy and Citrus expected to reach the upper 40s. Weak mid/upper level ridging will resume over the region by tomorrow, allowing temperatures to climb back up into the low to mid 80s. Afternoon sea breeze will help to ease temps near the coast. Otherwise, despite the sea breeze generation and decent daytime heating, a lack of moisture will preclude any convective development. Given low inland humidity values between 30-35% and our current drought situation, anyone burning outdoors should exercise extra caution the next couple of days . With all that said, no significant changes were made to the current forecast.

MARINE . Weak high pressure north of the region will keep relatively light winds and calm seas over the eastern Gulf waters into the weekend with an afternoon sea breeze shifting winds near the coast. High pressure sinks south Sunday into early next week with light- moderate winds shifting SE-S. Otherwise, no headlines or advisories are expected for the remainder of 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.
