(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 ktbw 181843 afdtbw area forecast discussion national weather service tampa bay ruskin fl 243 pm edt Sun aug 18 2019 Short term (today - Monday) The transition begins as upper level ridging extending from bermuda southwestward over the bahamas and southern florida starts to shift northward as the trough that has been over the east coast weakens and moves north. This will bring back a more summertime pattern as the winds shift to the east-southeast to start out the week. Showers and storms have been very limited today mainly over the nature coast. This pattern will continue for the next 24 hours as we transition to a more summerlike pattern. Atmospheric moisture will be on the decline starting tomorrow dropping below 2 inches for the first time in a couple of weeks. With the decreasing rain chances, temperatures will also warm back up to around average with upper 80's to low 90's expected each day. Long term (Monday night - Sunday) Mid level and surface troughing over the southeastern states and northeast gulf of late will gradually weaken as it lifts out to the northeast through Tuesday. In the wake of the trough mid level and surface ridging over the atlantic will rebuild in across the north central florida peninsula and eastern gulf through the remainder of the week and into next weekend with a return to a more typical summertime weather pattern across the forecast area under a developing southeast wind flow. After slightly drier conditions on Monday, increasing moisture (pw's returning into 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 each day, with a southeast steering flow favoring the highest pops and best convective coverage focusing along and to the west of the i-75 corridor during the afternoon and early evening hours along the east west coast sea breeze merger. The increasing moisture combined with slow moving storms will support some locally heavy rainfall each day, 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. Near seasonal level temperatures are expected with lows in the lower to mid 70s, with daytime highs around 90 to the lower 90s. Aviation We are starting out the day much drier than the past couple of days. Showers and storms are staying well to the north along the nature coast with no significant impacts expected at any of the terminals. Winds remain out of the southwest less than 10 knots with no aviation impacts expected. Marine High pressure ridging over southern florida lifts northward over the central gulf waters today and holds in place through mid week with fairly light winds and seas. The only impact over the coastal waters will be higher winds and seas in the vicinity of thunderstorms. && Fire weather Scattered to numerous showers and storms each day combined with high humidities will preclude any fire weather concerns through the period.

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. |
