GMZ800 Synopsis For The Coastal Waters From Bonita Beach To Suwannee River- 848 Pm Est Mon Jan 20 2020
Synopsis.. Interaction between a cold front south of florida and strong high pressure over the central u.s. Is producing gusty northerly winds across the eastern gulf of mexico. Will continue to hold scec tonight into Tuesday. The gradient further tightens on Tuesday afternoon between the high pressure over the ohio river valley and a trough of low pressure near the bahamas, which will likely bring conditions back up to sca level continuing through Wednesday afternoon. The high moves off the mid-atlantic coast by Thursday which will bring the winds around to the east and will decrease below any sca or scec level to close out the week.

Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 842 PM EST Mon Jan 20 2020

UPDATE. Chilly night ahead as coldest air mass of the season settles into the region through mid-week. Troughing aloft over the eastern CONUS coupled with Canadian high pressure at the surface that has migrated south into the Upper Midwest continues cold air advection into the state. Shortwave embedded within main jet stream evident in water vapor imagery currently scooting east across the Carolinas is helping squeeze out lingering mid/upper-level atmospheric moisture, which has resulted in a few high clouds streaming east/northeast across the peninsula early this evening. Most guidance indicates this cloudiness should diminish overnight allowing temps to fall precipitously to freezing or just below across the upper Nature Coast . mid 30s/low 40s central/interior . to mid 40s coastal/south. Continued light northerly flow will likely make feels-like temps a few degrees cooler.

A trailing shortwave analyzed over Missouri this evening will continue to dig southeast, reinforcing the cold air Tuesday into Wednesday as it moves into the Western Atlantic and develops a surface low just offshore, increasing northerly flow over the region. Well below normal temps expected to continue Tuesday afternoon, with highs in the low/mid 50s along/north of I-4 corridor, and the upper 50s to around 60 at locations further south.

AVIATION. VFR expected through period with northerly winds generally below 10 knots, increasing to 10 to 12 knots with the potential for a few higher gusts after 15Z.

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.
