Synopsis..A weak area of low pressure over the northeast gulf this afternoon will gradually wash out through Sunday as surface high pressure builds down the eastern seaboard. The high will move east into the atlantic early next week with the ridge axis extending back to the southwest across the central waters with a light southeast to southerly wind flow expected. A cold front will move into the northern waters on Wednesday, and into the south-central waters Wednesday night where it will eventually stall out through Thursday. As the front move into the area increasing winds and seas are expected, with a period of cautionary or advisory level conditions likely by late Wednesday into Thursday with some rough boating conditions developing.

Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 620 PM EST Sat Dec 7 2019

AVIATION. VFR through period with mid level clouds streaming over area. Flow in the lower levels become east Sunday with Atlantic moisture headed toward the Gulf Coast with sct-bkn040 in the afternoon.

PREVIOUS DISCUSSION. A weak area of low pressure over the northeast Gulf this afternoon will gradually wash out through Sunday as surface high pressure builds down the eastern seaboard. A few isolated showers will be possible over the northern gulf waters and over Levy county early tonight, otherwise pleasant dry weather is expected through Sunday with moderating temperatures. Temperatures tonight will be milder than previous nights with overnight lows in the lower to mid 50s across the Nature coast, mid to upper 50s central and south interior locations, and lower 60s along the immediate coast.

During Monday and Tuesday high pressure from the Atlantic extending southwest across the central peninsula will maintain dry weather with warmer temperatures. Another upper level trough and attendant cold front will approach from the west Tuesday night with the front moving south through the region during Wednesday and Wednesday night as a weak area of low pressure rides along it from the Gulf. Sufficient moisture should support some scattered showers along and ahead of the front as it moves into the region, before it stalls out across the south-central peninsula on Thursday.

Now during Thursday night into Friday models show low pressure developing over the central Gulf of Mexico ahead of a potent upper level trough which will be diving southeastward into the western Gulf from the southern Plains with the upper trough and surface low then tracking east-northeastward across the northern Gulf coast and northern Florida peninsula during Friday night, and then up along the mid Atlantic coast on Saturday.

As the low develops the remnant stalled frontal boundary across the south central peninsula will lift back to the north as a warm front. As this occurs deeper moisture will be drawn northward into the forecast area on a deep layered south to southwest wind flow. This moisture combined with increasing large scale lift and good dynamic support aloft will lead to increasing rain chances area-wide with the possibility of some isolated storms as well through Saturday as these features affect the area.

Warming temperatures can be expected tonight through early next week with overnight lows moderating into the 50s and 60s from north to south with daytime highs in mid to upper 70s on Sunday, and then lower to mid 80s Monday through Wednesday. Cooler temperatures will return Thursday through Saturday in the wake of the front and low pressure system.

MARINE. A weak area of low pressure over the northeast Gulf this afternoon will gradually wash out through Sunday as surface high pressure builds down the eastern seaboard. The high will move east into the Atlantic early next week with the ridge axis extending back to the southwest across the central waters with a light southeast to southerly wind flow expected. A cold front will move into the northern waters on Wednesday, and into the south-central waters Wednesday night where it will eventually stall out through Thursday. As the front move into the area increasing winds and seas are expected, with a period of Cautionary or Advisory level conditions likely by late Wednesday into Thursday with some rough boating conditions developing for small craft operators.

FIRE WEATHER. Humidity values are forecast to remain above critical levels into early next week with no fire weather hazards expected.

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.
