(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 ktbw 212352 afdtbw area forecast discussion national weather service tampa bay ruskin fl 752 pm edt Wed aug 21 2019 Update Some drier air over the area today (1.61 inches of precipitable water on the ktbw 12z sounding) resulted in thunderstorms being a bit slow to develop, but scattered to numerous storms eventually developed along sea breeze boundaries, and are still slowly working west towards the gulf coast early this evening. These storms are largely expected to taper off before midnight as they work west into the coastal waters. Some minor adjustments were made to the rain chance forecast for the early evening to keep up with radar trends. Otherwise, the forecast looks on track with even drier air expected on Thursday, with the bulk of the rain chances confined to southwest florida. Aviation A band of scattered sea breeze thunderstorms are still moving west across area terminals, with periods of MVFR or brief ifr lifr conditions expected as storms pass overhead. The storms are expected to taper off by around 01-03z, withVFR conditions holding through the morning hours. Scattered thunderstorms will be possible again Thursday afternoon, mainly over southwest florida |
around kpgd, kfmy, and krsw. Marine High pressure will continue to ridge across florida and into the northeastern gulf of mexico into the weekend, with generally southeasterly winds turning onshore with the afternoon sea breeze.

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. |
