Dense Fog Blankets South Florida, Storms Possible This Weekend

Inland areas see reduced visibility due to fog and smoke, with a chance of thunderstorms on Saturday.

Published on Feb. 27, 2026

A Dense Fog Advisory is in effect across inland South Florida through 9am as overnight fog and smoke from nearby wildfires have significantly reduced visibility in some areas. Once the fog clears, temperatures will warm quickly, reaching the low to mid 80s. There is a slightly better chance for storms on Saturday as a front approaches and deeper moisture moves in, especially across the East Coast. Rain chances decrease by Sunday as the front pushes through, leading to a quieter start to next week with a return to a breezy East wind.

Why it matters

Dense fog can create dangerous driving conditions, while the potential for storms on Saturday could impact outdoor plans and activities. The weather patterns also reflect the ongoing effects of climate change, with warmer temperatures and increased wildfire risk in the region.

The details

The dense fog that developed overnight is the result of a combination of factors, including calm winds, high humidity, and smoke from the National and Regal fires in the area. Visibility has dropped dramatically in some inland locations, prompting the issuance of a Dense Fog Advisory. Once the fog clears, temperatures will quickly warm into the low to mid 80s. On Saturday, a front approaching the region and increased moisture will bring a slightly better chance for thunderstorms, especially across the East Coast areas. By Sunday, the front will have pushed through, leading to a decrease in rain chances and a return to a breezy East wind to start the new week.

  • The Dense Fog Advisory is in effect through 9am this morning.
  • Temperatures are expected to reach the low to mid 80s this afternoon once the fog clears.
  • There is a slightly better chance for storms on Saturday afternoon, especially across the East Coast.
  • Rain chances will decrease by Sunday as the front pushes through the region.
