Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 823 PM EDT Sat Jul 11 2020

UPDATE. The area resides between upper low near the Yucatan Peninsula and large and broad upper trough over the the Eastern US. Tight pressure gradient earlier today produced breezy westerly winds and high dew point air off the Gulf and as expected gradient has relaxed with light W flow for tonight into Sunday. Afternoon convection has diminished in coverage and intensity but a few clusters of showers and storms continue this evening. Expect activity to wind down in the next few hours with clearing skies and warm overnight temps. Updated grids and forecasts on radar trends otherwise in good shape.

AVIATION. VFR expected with westerly flow this evening and overnight with VCTS again Sunday afternoon.

Prev Discussion. /issued 204 PM EDT Sat Jul 11 2020/

DISCUSSION . A trough of low pressure is in place across the area with high pressure to the south across Cuba. This puts westerly flow in place across the local area. An upper trough is also in place across the eastern seaboard, and with the extra upper energy aloft, scattered to numerous showers and storms will continue to be possible through the afternoon and early evening. A cold front will move through the area later tomorrow, with slightly drier air moving in and lowering rain chances across the northern half of the area. High pressure will then start to build back to the north for early next week with moisture moderating back across the area. The westerly flow continues through mid-week, then the ridge axis builds to the north of the area Thursday bringing a return to easterly flow across the area. Scattered to numerous showers and thunderstorms will be possible each day. Highs will remain in the lower to mid 90s each afternoon, with lows in the mid 70s to around 80.

MARINE . Westerly flow continues with a trough in place across the area. A boundary will push through the waters later Sunday, with winds and seas subsiding a bit from today. High pressure builds back to the north for the early part of next week, with the ridge axis lifting north of the area and turning winds to the east for the end of the week. Isolated to scattered showers and storms will be possible through the period, with winds and seas higher near the storms.

FIRE WEATHER . No concerns. Humidities will remain above critical levels through the period.

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