Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 822 PM EDT Mon Jun 14 2021

UPDATE (Overnight through Tuesday morning). The weather pattern remains on the unsettled side across the Florida peninsula due to deep moisture in place and a favorable westerly wind fetch off the eastern Gulf of renewed convective activity. Even as the sun is setting, additional showers and storms are generating here and there throughout west- central and southwest Florida. As often happens during these synoptic patterns, we are likely to see a brief lull in the convection during the later evening hours and first few hours after midnight. An this is a "lull" . not a completely dry period. However, all indications are that sct/nmrs showers and storms will get going again in the pre-dawn hours over the eastern Gulf and along the coast and be quite common through the morning hours of Tuesday. Similar to today, some will get more than others, but everyone in the region should be anticipating at least some rain during the morning hours, especially those with outdoor working or recreational plans.

Have increased the rain chances across the board starting around 5AM and lasting through the morning hours where fairly high potential exists for showers to at least be in the vicinity. The KTBW sounding profile this evening shows a very moist column with precipitable water around 2". NWP is in agreement that this moist and unstable column will not go anywhere through Tuesday, and in that case a persistence forecast in line with what happened today (Monday) seems like the most reasonable way to go.

AVIATION (00Z Tuesday through 00Z Wednesday) . An unstable atmosphere remains in place across all of west- central and southwest FL, providing a forecast that will support a the potential for a brief shower or storm at just about anytime through the evening. After midnight through the morning hours of Tuesday, conditions appear favorable for renewed areas of scattered to numerous showers/storms to roll ashore off the Gulf . impacting all terminals. Winds will remain SW/W around 10 knots overnight. Majority of storms look like they will migrate east of the terminals after 18Z.

Prev Discussion . /issued 255 PM EDT Mon Jun 14 2021/

DISCUSSION . The mid/upper level trough will linger over the eastern U.S. through midweek with the surface ridge axis to our south keeping a moist southwest to west flow across the region. This will continue to cause scattered to numerous showers and thunderstorms through Wednesday with the best timing over the coastal waters and near the coast during the late night and early morning hours then moving east across the peninsula for the remainder of the day. However, with the abundant tropical moisture in place, precipitable water around 2 inches, there could be a shower or thunderstorm at almost anytime. Main hazards with the convection will be gusty winds and locally heavy rainfall, and cannot rule out a brief waterspout.

Late in the week into the weekend the trough begins to move east as a potential tropical system moves north into the western Gulf of Mexico with the surface ridge moving north into the area. This will allow the low level flow to back to a more south to southeast direction and with plenty of moisture persisting we'll see more scattered showers and thunderstorms, especially during the afternoon and evening hours.

AVIATION . Scattered showers and thunderstorms are expected through the TAF period which could cause some MVFR/local IFR conditions. Otherwise, mainly VFR conditions are expected. Southwest winds 10 to 15 knots this afternoon will decrease to around 10 knots or less after sunset then increase back to 10 to 15 knots by late Tuesday morning once again.

MARINE . High pressure ridge axis over the Florida Straits will maintain moderate southwest to west winds and 2-3 ft seas across the eastern gulf waters into midweek. Expect scattered showers and thunderstorms at almost anytime through Wednesday with winds and seas higher near this convection. Wind begin to shift to a more south to southeast direction late in the week into the weekend as the ridge axis drifts north.

FIRE WEATHER . No fire weather hazards are expected for the next several days as relative humidity values will remain above critical levels.
