Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 704 PM EST Mon Jan 27 2020

AVIATION. VFR expected with the exception of southern terminals where lower CIGS are possible through the overnight hours, causing periods of MVFR conditions. Winds out of the northeast generally AOB 7 knots.

Prev Discussion. /issued 247 PM EST Mon Jan 27 2020/

DISCUSSION . A short wave trough and attendant weak surface low will dampen out as they move across the southern peninsula early tonight and then east into the Atlantic overnight into Tuesday. Any lingering light showers or rain will shift southeast in tandem with these features early tonight with drier conditions and decreasing cloudiness expected overnight into Tuesday as high pressure noses in from the north. The dry conditions on Tuesday will be short lived though as the very progressive upper air pattern across the Conus pushes yet another short wave trough and weak surface low across the northern Gulf coast during Wednesday and then across the north- central Florida peninsula Wednesday night bringing with it the next chance for some showers or light rain to the forecast area.

Now during Thursday zonal flow aloft and high pressure to the north of the area will support pleasant dry weather, but this dry weather again will be short lived as models show another potentially stronger short wave trough and deeper surface low evolving over the western Gulf Thursday night with these features then heading our way during Friday and into the start of the upcoming weekend with increasing rain chances once again.

As mentioned the latest models show a much stronger system possibly impacting the area during Friday and into the start of the weekend, although the overall strength, timing, and exact placement of these features differ some between the models so will be cap rain chances in the 30 to 50 percent range for now, but as we move through the remainder of the week those numbers could increase as better model continuity develops with the highest rain chances likely occurring on Saturday as this storm system affects the area.

In addition to the rain chances we will also need to monitor for the possibility of some thunderstorms which could become strong to severe as shear and convergence increases across the region with this potent system. Breezy, dry, and cool weather will return Saturday night through Monday in the wake of this storm system as high pressure builds in from the western Gulf. Near seasonal level temperatures through the end of the week will fall to below normal late in the weekend and into early next week in the wake of the potentially stronger system mentioned above.

MARINE . Weak low pressure will exit to the east of the Gulf waters tonight with winds becoming northeast to north in the 10 to 15 knot range overnight into Tuesday morning, the diminishing to around 10 knots during Tuesday afternoon and night. During Wednesday another weak area of low pressure will affect the waters bringing with it increasing chances for showers. High pressure will again build in during Thursday with dry weather returning, but this will be short lived as another potentially stronger storm system with increasing winds and rain chances affects the waters on Friday and into the start of the upcoming weekend. Wind and seas should remain below 15 knots and 5 feet through Thursday with potentially higher wind and seas possible late Friday into Saturday as the aforementioned storm system impacts the waters.

FIRE WEATHER . Drier air will filter into the region later tonight into Tuesday. This drier air will support pockets of humidity values aob 35 percent across interior portions of the Nature Coast counties Tuesday afternoon, however with low ERC values and winds less than 15 mph no Red Flag conditions are expected. Humidity values should remain above critical levels on Wednesday and through the end of the week with no other fire weather hazards expected at this time.

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