Satellite imagery over Florida shows a well-defined surface ridge axis aligned east to west from the Atlantic and across Lake Okeechobee. Note the clockwise turning of the cumulus clouds over the ocean. Showers and thunderstorms can also be seen developing along the east coast sea breeze near and north of the ridge axis. Upper level winds (note the cirrus anvil clouds) are from NNE to SSW as an upper level low approaches Florida from the east. Coverage and intensity of thunderstorms over the peninsula will increase through the afternoon and early evening.
Satellite imagery over Florida shows an upper level low pressure trough extending southward over the eastern Gulf of Mexico. At the surface, high pressure ridge axis is currently aligned east to west across extreme south Florida and the Florida Straits. This synoptic setup once again places the peninsula within a deep layered, moist, southerly wind flow. In such a regime all that is generally needed to generate widespread showers and thunderstorms is strong diurnal heating, instability creation, and local boundaries, i.e. sea breezes. Today will be no different. All activity will generally travel south to north and intensify along boundary collisions.

Satellite imagery over Florida once again shows deep layered southwest to northeast flow of all cloud layers. Showers and thunderstorms develop over the eastern Gulf of Mexico in the morning hours and move over the west coast of Florida primarily during the morning. These storms then progress eastward and re-energize along the west coast sea breeze while tapping in to the diurnal heating and moisture. An increase in coverage will occur as surface heating and boundary collisions occur as all activity continue to travel towards the northeast.
Satellite imagery over Florida continues to show a deep layered southwest to northeast wind flow. Showers and thunderstorms developing in the moist unstable air mass quickly travel towards the northeast as do the upper level cirrus clouds, note the cell along the west coast with fast moving anvil. Thunderstorm coverage will increase throughout the late morning and afternoon hours.
Satellite imagery over Florida shows showers and thunderstorms developing in the unstable atmosphere as diurnal heating increases over the peninsula. Thunderstorm steering level winds will continue to push all activity towards the northeast as upper level low pressure sits over the eastern Gulf of Mexico and southeastern U.S.
Satellite imagery over Florida shows a large cluster of thunderstorm over the eastern Gulf of Mexico. This cluster will travel across southeast across the southern half of the peninsula while additional showers and thunderstorms will develop over the state where abundant surface heating and higher moisture levels exist. Upper level winds are blowing the anvil clouds towards the northeast as upper level low pressure sits over the eastern Gulf.
Satellite imagery over Florida shows strong and severe thunderstorms over the northern half of the peninsula traveling towards the south and southeast. These storms are capable of producing hail, high winds, frequent lightning, and heavy rains. Heed all warnings.
Satellite imagery over Florida once again shows developing showers and thunderstorms along the enhanced west coast sea breeze traveling eastward. Deep moisture currently bisecting the peninsula with higher contents to the north will contain the greatest coverage of showers and thunderstorms. Upper level winds continue to blow anvil clouds towards the west.
Satellite imagery over Florida shows showers and thunderstorms along the west coast sea breeze traveling towards the east coast. While unlikely, if an east coast sea breeze develop sit will hug the coastline and merge with the eastward moving thunderstorms later this afternoon. Upper level winds continue to blow anvil clouds towards the west. Lower moisture content levels will limit thunderstorm development across the southern half of the peninsula.
