Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 316 AM EDT Sun Sep 20 2020

DISCUSSION. Mid level ridging over FL and the adjacent waters this morning expands northward toward a more robust ridge that shifts from the Mississippi Valley to the eastern US by late Mon. At the surface high pressure centered in Quebec, Canada stretches down the eastern states to FL . where a weakening frontal boundary eases south. A weak wave/low is on the boundary off the FL east coast. Tropical Storm Beta continues in the western Gulf of Mexico while Hurricane Teddy moves toward Bermuda. Please see National Hurricane Center advisories for details. The high pressure to the north along with the wave/low just to the east of the state will keep a brisk to robust northeast flow in place . with a Lake Wind Advisory for counties from Tampa Bay east and north. The wave/low slides west along the boundary as it slips south today with enough moisture and lift for scattered to numerous showers and some thunderstorms this morning into the late afternoon-early evening. For Mon the winds continue near or in Lake Wind Advisory criteria as drier air filters in . limiting rain chances and shunting higher values to the south. Temperatures run on the warm side of normal through Mon morning then cool during the day with afternoon highs a couple of degrees below normal in the north and around normal elsewhere.

Tue through Sat: The eastern US mid level ridging flattens down across FL then begins to slide east for the weekend as a low or short wave trough on the TX coast tracks toward the Mid-Mississippi Valley with broad troughiness in it's wake. The Canadian high pressure relocates to the Mid-Atlantic states midweek then slips out over the Atlantic. This high pressure dominates the east Gulf and FL through the period as a weak boundary resides in far south FL.

The dry air noted above lingers into midweek with low rain chances. Then . as flow becomes easterly then southeasterly . moisture increases with higher rain chances for the end of the week into the weekend. Temperatures range from just below to around normal.

AVIATION. 20/06Z. Anticipate MVFR CIGS along with ISOLD SHRA spreading across the aerodromes in NE flow during the next few hours and continuing into early afternoon. Then prevailing VFR although VCTS may result in brief MVFR/IFR TIL 00-02Z. NE winds continue with gusts in the 25-30KT range.

MARINE. High pressure building in from the north along with tropical systems to the west and east . see National Hurricane Center advisories for details . will maintain hazardous marine conditions through early in the week. The Small Craft Advisory continues in the north and will be expanded southward this afternoon and remains in place into Mon. Bay and harbor waters will have Exercise Caution in place. The high pressure settles south during midweek with veering and diminishing winds.

FIRE WEATHER. Breezy northeast winds for the next couple of days with some drier air Mon-Wed. No critical humidities are expected but dispersions will be high for most counties today and Mon.

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