West Palm Beach, FLA. (WPEC) — South Florida will continue to experience typical summer conditions through Monday, with mostly sunny skies, hot temperatures, and scattered afternoon thunderstorms—mainly over interior and southwestern areas.
A weakening mid to upper-level ridge—a broad zone of high pressure in the middle and upper layers of the atmosphere—remains the dominant weather feature, keeping easterly surface winds (winds blowing from the east) in place. This pattern favors the east coast sea breeze, which pushes inland during the day and helps trigger thunderstorms, especially over the Everglades and Southwest Florida.
Forecast models show a slightly drier air mass today, which will limit rain chances and keep heat index values (how hot it feels when humidity is factored in) just below levels that would trigger heat advisories. Moisture levels are high enough to support scattered thunderstorms in the early evening, especially inland. A few brief showers or isolated storms may pop up along the east coast early in the morning, but most of the day will be sunny.
Monday Outlook
Monday will follow a similar pattern, with morning sunshine and afternoon storms developing as the sea breeze moves inland. However, Hurricane Erin—currently offshore in the Atlantic—will begin to influence local weather. Erin’s broad circulation will shift surface winds to the north, creating northeast winds over eastern South Florida and northwest winds over the southwest. This shift could subtly affect where storms form and how they move…
