The first storms look to arrive first in south Palm Beach County during the early afternoon before spreading north. Some storms have the potential to turn strong, producing wind gusts around 60 mph and near quarter-sized hail.

Areas that see repeated rounds of heavy rainfall may see some localized flooding.

Once the front moves through, a noticeable change arrives Tuesday morning with chillier temperatures. Parts of the Treasure Coast and Okeechobee County will wake up to the lower 50s. Highs will drop below average, struggling to make it into the 70s on Tuesday and Wednesday.
