GMZ800 Synopsis For The Coastal Waters From Bonita Beach To Suwannee River- 234 Pm Edt Mon Apr 19 2021
Synopsis..A quasi-stationary frontal boundary over the south central gulf waters this afternoon will meander about through mid week. Ample moisture and instability combined with the front will support periods of showers and Thunderstorms across the waters tonight through Wednesday with gusty winds, frequent lightning, locally higher seas, and perhaps even a waterspout possible near the strongest storms. During Wednesday a secondary reinforcing cold front will move south through the waters during the day with a slight uptick in winds toward cautionary levels possible Wednesday night into early Thursday in the wake of the front. Pleasant dry boating conditions expected during Thursday and Friday as high pressure builds in over the region.

Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 223 PM EDT Mon Apr 19 2021

. Strong to Severe Storms Possible Through Tuesday . . Locally Heavy Rainfall Possible Through Tuesday . . High Risk Of Rip Currents Along Area Beaches Through Tuesday Night .

DISCUSSION. A quasi-stationary front across the south-central Florida peninsula combined with ample moisture, upper level divergence, and weak vort lobes moving across the region within the strong mid level southwest to west wind flow will continue to support an enhanced rainfall potential across the forecast area through mid week with some locally heavy rains possible, especially in areas where the training of storms occur with some minor flooding of low lying and poor drainage areas possible, and much of the forecast area remains in a Marginal Risk for excessive rain through the period.

In the interim though ongoing convection across the region this afternoon should wind down early tonight as impulses aloft move away from the region and overall low level convergence weakens, with mainly partly to mostly cloudy skies expected overnight. Hi- Res CAM guidance for the most part is in agreement with this, but given the presence of the front, abundant moisture in place, and divergence aloft will retain low rain chances (Pops 20-30%) in the forecast for the overnight time frame.

On Tuesday the front combined with ample moisture and additional short wave energy advancing eastward from the Gulf, and good upper level divergence should help to develop numerous showers and storms over the Gulf waters during the pre-dawn hours, with this convection then moving onshore toward sunrise with another day with widespread showers and scattered storms expected with some strong to severe storms possible. In addition the threat for additional heavy rainfall with localized flooding of low lying and poor drainage areas will continue as well. Similar to today considerable cloudiness and elevated rain chances will keep temperatures near seasonal norms with highs in the upper 70s to lower 80s expected area-wide.

During Wednesday a secondary cold front will move into the region during the day. Ongoing showers and storms across central and southern zones during the morning hours will gradually end from north to south during the afternoon as the front and drier air in its wake moves into the forecast area through Wednesday night. In the wake of the front cooler temperatures can be expected with lows Wednesday night falling into the lower to mid 50s across the Nature Coast, and upper 50s to lower 60s central and south. High pressure will build in over the southeastern U.S. and Florida through the end of the week with pleasant dry weather expected during Thursday and Friday with daytime highs remaining near seasonal norms with highs in the lower 80s each day. During next weekend models show another area of low pressure moving across the lower Mississippi valley and Southeastern states, and then up along the mid Atlantic coast with a trailing cold front approaching and moving into the region on Sunday bringing with it increasing chances for showers and storms along and ahead of it. At the moment there are some model timing differences with regards to this frontal passage, so for now will keep inherited low rain chances (Pops 20-40%) in place and wait to see if better model continuity develops in the coming days.

AVIATION. Intervals of MVFR/IFR cigs/vsbys will be possible at the terminals during the next 24 hours as areas of showers and scattered storms continue to move across the region. Outside of the convection VFR is expected. West to northwest winds around 10 knots with higher gusts near TSRA the remainder of this afternoon will become light and variable after 00Z tonight, then becoming southwest to west and increasing to 10 to 12 knots after 15Z on Tuesday with higher gusts in the vicinity of TSRA.

MARINE. A quasi-stationary frontal boundary over the south-central Gulf waters this afternoon will meander about through mid week. Ample moisture and instability combined with the front will support periods of showers and thunderstorms across the waters tonight through Wednesday with gusty winds, frequent lightning, locally higher seas, and perhaps even a waterspout possible near the strongest storms. During Wednesday a secondary reinforcing cold front will move south through the waters during the day with a slight uptick in winds toward Cautionary levels possible Wednesday night into early Thursday. Ongoing scattered showers and storms over the central and southern water Wednesday morning will gradually end from north to south during the afternoon with the frontal passage as drier air moves into the region in the wake of the front, with pleasant dry boating conditions expected to end the week as high pressure builds in over the region.

FIRE WEATHER. A stationary front across the south central Florida peninsula will continue to support elevated rain chances across all of west central and southwest Florida through early Wednesday. The elevated rain chances will keep humidity values well above critical levels through mid week with no Red Flag conditions expected. Drier air will move into the region Wednesday night into Thursday in the wake of a second cold front, but humidity values are forecast to remain above critical levels. Weak 20 foot winds and transport winds will support low dispersions across the region on Tuesday, otherwise no other fire weather concerns are expected.
