Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 205 PM EST Thu Jan 23 2020

DISCUSSION. The upper ridge has slipped off the eastern seaboard, which puts Florida in a more warm and moist air mass on the back side of this ridge. This pattern will hold over the area through Friday before being replaced by another upper low and trough that is currently located over Kansas. Models currently have this low and trough slowly moving east just south of the Great lakes through the weekend and exiting the northeast U.S. by early Monday morning. Another trough moves through the southeast U.S. on Monday and will lend support to a developing surface low in the Gulf of Mexico.

On the surface, the high pressure center has moved over the mid- Atlantic states and continues to ridge south-southwest along the eastern seaboard, over Florida and into the Gulf of Mexico. This will help keep an easterly wind flow and warm temps over Florida through Friday. The next weather system develops through the Mississippi River Valley with a cold front extending south into the central Gulf of Mexico late Thursday into Friday. Winds turn southeast, then southwest ahead of this system and will warm things up today and on Friday. This system will move eastward with the cold front moving across Florida on Friday bringing increasing rain chances, with the highest coverage over the eastern Gulf of Mexico waters. High pressure ridges in from the west behind this front producing sunny skies and northerly winds once again that will bring another slight cool down on Saturday and Sunday. Models continue to develop another area of low pressure in the gulf by Monday, bringing a good chance of showers to the area as it passes over the Florida peninsula. High pressure builds in once again by Tuesday bringing clearing conditions and seasonal temperatures.

AVIATION. VFR conditions with east-northeast winds less than 10 knots expected through the day. As we saw this morning, low CIGs and VSBY will be a concern early Friday morning with more IFR/LIFR conditions possible, so hold low clouds in the forecast from 07-15Z to cover this. VFR expected after 15Z tomorrow. No other aviation impacts expected.

MARINE. High pressure has moved over the New England states and continues to ridge south-southwest along the eastern seaboard. The gradient has weakened, therefore the winds and seas are expected to remain around 10 to 15 knots or less and seas 2 feet or less for the next couple of days. A cold front moves through the coastal waters on Friday producing a chance of showers. High pressure builds behind this front on Saturday and Sunday producing some gusty north-northwest winds, but not expected to reach SCA or SCEC level at this time.

FIRE WEATHER. High pressure ridges in from the north keeping rain-free conditions and increasing RH values for the next couple of days. A weak cold front moves through the area late Friday bringing a slight chance of showers. Some more dry and cool air moves in on Saturday and Sunday, but not expected to drop below any fire weather threshold.

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.

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