Gulf coastal waters from Bonita Beach to the Suwannee River out 60 NM - GMZ800
240 PM EDT Tue Jul 27 2021

High pressure from the Atlantic extending west across the southern Florida peninsula and Straits will support tranquil boating conditions over the Gulf waters tonight and through the remainder of the week and into upcoming weekend with light southwest to west winds and slight seas expected with an enhanced onshore sea breeze component developing along the coast each afternoon. Wind and seas will be higher in the vicinity of thunderstorms each day, otherwise no headlines are expected.

...Locally Heavy Rain Possible The Next Few Days... ...Heat Indices In The 100-105 Degree Range Each Afternoon...

Showers and thunderstorms will continue to develop over the forecast area the remainder of the afternoon within a very moist and unstable air mass covering the forecast area. Slow and erratic moving storms along the sea/outflow boundaries will support locally heavy rainfall with some localized flooding of low lying and poor drainage areas possible. In addition, frequent lightning strikes, and some gusty winds will accompany the storms. The showers and storms will gradually wind down during the evening, but additional showers and storms should redevelop over the Gulf waters late tonight within the very moist southwest flow with this convection then pushing onshore along the coast early Wednesday morning. It will be a warm and very muggy night especially along the coast where lows around 80 can be expected, with mid 70s inland.

Now during the remainder of the week and into next weekend the Subtropical ridge will set up shop from the Atlantic and extend west across the southern peninsula and Straits with a southwest to west flow regime pattern expected as an upper level trough develops along the eastern seaboard. This pattern will support scattered showers and storms over the Gulf waters and along coastal areas during the late night and early morning hours, with the convection then shifting east and increasing in areal coverage over inland and eastern sections of the peninsula each afternoon along the sea breeze boundaries where the highest rain chances (probability of precipitation 50-70%) will reside each day.

A weak steering flow will support slow moving storms so some locally heavy rainfall and minor flooding of low lying and poor drainage areas will be possible each day. In addition, frequent lightning and some gusty winds will accompany the storms. It will remain hot and muggy through the period with overnight lows running above normal especially along the coast due to the onshore flow where lows near 80 can be expected, with mid 70s inland, with daytime highs climbing into the lower to mid 90s each afternoon prior to the onset of the storms.

Marine
High pressure from the Atlantic extending west across the southern peninsula and Straits will support tranquil boating conditions over the Gulf waters tonight and through the remainder of the week and into upcoming weekend with light southwest to west winds and slight seas expected with an enhanced onshore sea breeze component developing along the coast each afternoon. Wind and seas will be higher in the vicinity of thunderstorms each day, otherwise no headlines are expected.

Fire Weather
Ample moisture will support scattered to numerous diurnal sea breeze driven showers and thunderstorms over the forecast area each day through the end of the week and into the upcoming weekend. Lightning strikes from the storms will pose a risk for fire development, otherwise humidity values are forecast to remain well above critical levels with no other fire weather concerns expected.
