GMZ800 Synopsis For The Coastal Waters From Bonita Beach To Suwannee River- 324 Am Est Tue Dec 10 2019
Synopsis.. High pressure will persist over the waters through tonight. A cold front will move into the northern waters on Wednesday, and then into the central waters Wednesday night where it will stall out through Thursday. Ahead of the front, there is an increasing threat for sea fog off the nature coast, which may eventually extend south to the mouth of tampa bay. SEa fog may persist through Wednesday morning over the cooler northern shelf waters. As the front moves into the area increasing northeast winds and seas are expected, with a period of cautionary or near advisory level conditions possible by late Wednesday into Thursday, especially across the central and northern waters.

Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 303 AM EST Tue Dec 10 2019

DISCUSSION. Broad upper/mid level troughing is currently sprawled across much of the continental US, with weak ridging centered over the Florida Straits. At the surface, the sub tropical ridge axis extends from the Atlantic across the central Florida Peninsula into the eastern Gulf of Mexico, while a cold front associated with the upper level troughing is pushing into the Gulf Coast region. This pattern is setting up light southerly low level flow over Florida, setting up a warm and moist environment. This low level moisture is already leading to some patchy fog over the interior, which should continue to expand in coverage through just after sunrise this morning. Although the southerly flow is fairly weak, some pockets of sea fog cannot be completely ruled out today and tonight. Otherwise, warm and pleasant conditions will hold today, with only isolated showers expected in the afternoon, mainly over the interior.

The front will slowly move southeast through the forecast area Wednesday and Thursday, bringing increased rain coverage and winds increasing and turning to northeasterly behind the front. With the slow forward motion of the front, most of the area will see chances for patchy fog again Wednesday morning, although increasing cloud cover and wind speeds will prevent more widespread fog from developing. Since the front will not make a quick or clean passage, the only areas to see cooler or less humid air will be mainly over the Nature Coast, with well above normal temperatures remaining from around Interstate 4 south.

A shortwave trough swinging through the northern Gulf of Mexico Thursday night and Friday will help develop a weak surface low, that will lift northeast into Florida Friday, dragging another weak cold front through the Florida Peninsula Friday night. This will result in more showers expected Friday and Saturday, and slightly cooler temperatures Saturday night and Sunday, although temperatures will remain above normal for mid December. High pressure will fill in Sunday night and Monday, allowing temperatures to begin to climb back up yet again.

AVIATION. Some patchy fog or MVFR ceilings will be possible through just after sunrise this morning, most likely around KLAL and KPGD. Then mostly VFR conditions will hold through the rest of the day, although occasional MVFR ceilings cannot be ruled out.

MARINE. High pressure will ridge across the Florida Peninsula and into the eastern Gulf of Mexico today, with light winds and seas continuing. Deep moisture ahead of an approaching weak cold front will allow for the possibility of sea fog reducing visibility, mainly over the coastal waters off the Nature Coast. This front will slowly sag southeast through the area Wednesday and Thursday, with winds turning to northeasterly and increasing to near advisory levels behind the front, as well as bringing a few showers into the area.

An area of low pressure will develop in the northern Gulf of Mexico late in the week and lift northeast into northern Florida Friday, dragging another cold front through the waters through early Saturday. This system will bring additional showers, and perhaps another period of cautionary or advisory level winds and seas.

FIRE WEATHER. Relative humidity is not expected to drop to critical levels through the next several days.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
