Another cold front will move through the area Saturday, turning winds to the northwest for a day. High pressure then quickly builds in for Sunday, with light winds. Wind speeds linger in the exercise caution range for the rest of the morning, but then winds and seas are generally expected to remain below headlines for the next few days. There is some potential for sea fog to develop over the waters mainly north of tampa bay on Friday night and early Saturday, but this will continue to be Monitored over the next day or so.

Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 633 AM EST Thu Dec 12 2019

AVIATION. Areas of MVFR/IFR cigs remain across the region and are generally expected to continue through the rest of the morning. Some breaks will be possible, especially this afternoon and especially for southwest Florida terminals, but overall a tricky and messy forecast for the next 24 hours. Winds remain east/northeast with some gustiness, though those gusts are forecast to be under 20 knots.

Prev Discussion. /issued 215 AM EST Thu Dec 12 2019/

SYNOPSIS .

The remnants of the front stretches across Central Florida with weak short waves flowing above. The result will be a cloudy day and some showers. The showers will be mainly inland today, tomorrow the focus will be closer to the coast.

By the weekend another front moves through and while this front will also be weak and will dissipate somewhere over the state. With this front however the deep layer trough will flatten out and the flow become zonal. The result will be a fantastic weekend with seasonal temperatures and drier conditions.

Enjoy it while you can because by midweek a weak deep layer trough digs into the Gulf and with it returning moisture. In fact I would not be surprised to see another sea fog situation set up mid next week as low 70s dewpoints advect over ocean temperatures around 70 degrees give or take a couple degrees.

AVIATION .

The frontal boundary or what is left of it stretches across the state from about the Bay Area to the Cape. This will be the focus of the low clouds overnight and tomorrow. The doesn't mean Ft. Myers area airports will not see MVFR ceilings, just there will be more breaks there. I introduced a TEMPO group with the ceilings but may need to amend that as the morning progresses.

MARINE .

Winds will decrease as the day progresses. I will let the SCA expire this morning and replace it with a SCEC into the evening. there are no other marine issues through the forecast period.

FIRE WEATHER .

Expect light winds, overcast skies, increasing low level moisture and a few showers especially Eastern Polk and Highlands counties today and the Nature Coast on Friday. Expect drier air over the area Sunday.

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.
