Our pattern of scattered showers and storms mainly throughout the afternoon across Southwest Florida continues Wednesday.

A few showers will be possible near the coast early and will gradually trek inland due to a strong Gulf sea breeze. There’s also the potential for some early patchy fog, too.

The heat and humidity is back in full force by the second half of the day. Highs peak in the low-mid 90s with heat indices 101 – 106°.

One big change occurs locally on Thursday. A ridge of high pressure builds into the Gulf of Mexico, which will bring slightly drier air to the upper levels of the atmosphere.

This will limit overall storm potential. However, that all shifts back to “normal” by Friday and the weekend.

In the tropics, a weak frontal boundary is forecast to move offshore of the southeast coastline by late week and into the weekend. As a result, there will be a low, 20% of tropical development within the next 5 days.
