Afternoon convection that mainly impacted the extreme eastern counties today is winding down, but a few pre-frontal showers have developed over the last hour across the greater tampa bay region and the adjacent coastal waters. Have some low pops in through the overnight hours as well as some patchy fog and this looks on track. The front will gradually push south through the area through the day Tuesday with high pressure ridging in for mid-week. No updates planned. Aviation MVFR ifr or lower will impact the terminals overnight with some patchy fog also developing. Ceilings will lift through the late morning, and then gradually clear out through the afternoon as the front moves through. A few afternoon storms will be possible across the southern terminals. |
Marine The front will push through the area tomorrow with winds turning to the W NW as high pressure builds in from the west. Wind speeds should remain AOB 15 knots through the period.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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. |
