(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 ktbw 191825 afdtbw area forecast discussion national weather service tampa bay ruskin fl 225 pm edt Mon aug 19 2019 Short term (tonight - Tuesday) Surface mid level ridging from the western atlantic extending west across the north-central florida peninsula will remain in place through the period with an east-southeast wind flow continuing across the forecast area. Scattered showers and storms over the region early tonight will end by sunset with skies becoming partly cloudy overnight. On Tuesday increasing moisture (pw's in the 1.8 to 2+ inch range) combined with daytime heating will support scattered to numerous diurnal sea breeze driven showers and storms across the forecast area during the afternoon with a southeast steering flow favoring the best convective coverage and highest pops (60 percent) setting up along and to the west of the i-75 corridor during the late afternoon and early evening hours. Slow moving storms will support locally heavy rainfall and with the ground remaining quite saturated from the recent heavy rains the threat of some localized flooding and additional rises on area rivers will continue to be a problem. Temperatures will run near normal with lows tonight in the lower to mid 70s, with daytime highs on Tuesday climbing to around 90 to the lower 90s. Long term (Tuesday night - Monday) The bermuda high ridge has shifted northward and will be the dominant weather feature through the long term period. This will keep us in a more typical summertime pattern with an east-southeast wind flow. This will support daily showers and storms developing along the east coast sea breeze early afternoon and transiting westward. Winds will be light enough for the west coast sea breeze to push inland each afternoon as well. Sea breeze collisions combined with daytime heating and abundant moisture (pwat between 1.7 - 2.0 inches) will allow for scattered to numerous showers and storms each afternoon. Some of these storms could produce heavy rainfall, but we are not expecting a daily wash-out like we have seen the past couple of weeks. Many local rivers are well above average with several in or near flood stage. Any additional rainfall |
over those river basins will continue to cause elevated water levels in those locations. Temperatures will hover right around average with low to mid 90's each afternoon and mid 70's overnight. Aviation Brief MVFR CIGS vsbys may impact the terminals between 20-01z as scattered shra tsra develop over the region and have handled with vcts for now, otherwiseVFR is expected during the next 24 hours. East-southeast winds at 6 to 8 knots will become west to northwest at the coast terminals after 19z as the sea breeze develops with light east to southeast winds returning after 01z tonight. Marine High pressure across the region will support tranquil boating conditions over the gulf waters through the remainder of the week with southeast winds around 10 knots with seas of 2 feet or less with an onshore sea breeze component developing along the coast each afternoon. Wind and seas will be higher near late afternoon and evening thunderstorms, otherwise no headlines are expected.

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. |
