(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 ktbw 230716 afdtbw area forecast discussion national weather service tampa bay ruskin fl 316 am edt Fri aug 23 2019 Discussion Easterly flow regime remains in place across the area today as atlantic ridge is positioned north of the area. To the southeast, an inverted trough tropical wave is moving towards the southern fl peninsula. This will bring deeper moisture over the southern portion of the forecast area today which will allow for likely pops across SW florida this afternoon and evening. Across the nature coast, atmospheric moisture remains lower and thusly rain chances there should be in the 20-30 percent range. A weak seabreeze will likely develop and push inland in the vicinity of the i-75 corridor which could spark some shower and storm development in this area. Any convection will move west out into the eastern gulf during the evening hours with skies becoming mostly clear to partly cloudy overnight. Similar weather is expected on Saturday with deeper moisture perhaps shifting a bit further north. During Sunday and Monday a weakening frontal boundary will drift into the southeast states with the models developing a weak low, perhaps tropical in nature, off the florida east coast that moves northeast away from the region. This pattern will setup a more south to southwest flow across the area and with ample moisture remaining in place we'll continue to see unsettled weather with scattered to numerous showers and thunderstorms. As is typical with this setup the best timing for the convection will be over the coastal waters and near the coast during the late night and morning hours then shifting inland during the afternoon and evening. Temperatures will run near climatological norms through the period. |
Aviation Vfr conditions expected through the rest of the morning and into early afternoon. Scattered to numerous showers and thunderstorms are expected to develop during the afternoon, causing brief periods of MVFR ifr conditions as storms move over individual terminals.

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. |
