Mix of sun and rain this week in South Florida

With the atmosphere still unsettled, South Florida likely will see scattered showers and storms by Monday afternoon.

Monday's forecast: Mostly cloudy, highs in the low 90s and lows in the upper 70s. There is a 40 percent chance of showers and storms.

During the rest of the week, expect to see a more typical summer pattern, with sun in the mornings and a good chance of storms developing later in the day, the National Weather Service in Miami said.

Tropics: The National Hurricane Center is monitoring a broad area of low pressure over the Bay of Campeche, giving it a 20 percent chance of developing over the next 48 hours.

The disturbance is drifting northwest, bringing heavy rains to eastern Mexico and Central America, according to the hurricane center's 8 a.m. Monday tropical outlook.

Over the next couple days, upper-level winds might become more conducive for development, senior hurricane specialist Richard Pasch said. The disturbance poses no immediate threat to Florida.
