Isolated to scattered thunderstorms are forecast across the Florida Keys and far south Florida today. Severe thunderstorms appear unlikely. ...Synopsis and Discussion... A large upper cyclone will encompass much of the central and eastern states today. A broad area of enhanced west-southwesterly mid-level winds will remain over the Southeast through tonight. A low-amplitude, southern-stream shortwave trough is forecast to move quickly northeastward today across the Gulf of Mexico and FL. A remnant cold front located over the FL Straits should tend to remain south of the Keys and south FL as weak surface cyclogenesis occurs ahead of the approaching shortwave trough, with most guidance showing northerly low-level winds prevailing across these areas. Still, enough MUCAPE should be in place to support isolated to scattered thunderstorms later this morning. Some guidance shows a loosely organized band/cluster of convection approaching the FL Keys at the start of the period (around 12Z). This activity should generally remain elevated, especially with northward extent into south FL. Even so, occasional strong/gusty winds may occur over nearshore waters as these thunderstorms move quickly eastward over the FL Straits and towards the Bahamas through the day. Thunderstorm potential across the remainder of the CONUS appears minimal today and tonight. ..Gleason/Bentley.. 12/28/2023 Read more View the full article Quote Link to comment Share on other sites More sharing options...
