Thanks to an unsettled atmosphere, we can expect scattered showers and storms by this afternoon. It also should be hot with feels-like temperatures approaching or exceeding 100 degrees.

South Florida's Tuesday forecast calls for partly sunny skies with highs in the low 90s and overnight lows in the upper 70s. There is a 50 to 60 percent chance of rain.

The rain chance eases slightly to 40 percent on Wednesday.


What dust? Insights from Jim Lushine, our resident weather expert:

Last week an impressive cloud of Saharan dust wended its way across the Atlantic, apparently heading toward the U.S. TV meteorologists were touting its arrival by Monday.

Although there were clouds on Monday, in between the sky is blue and the Air Quality Index was good. Where did the dust go? The short answer is: into thin air.

Because the eastern Atlantic Ocean has cool ocean currents, the instability (upward and downward air motion) in that area is limited.

However, the ocean water becomes warmer as you go farther west, instability increases and the dust spreads more upward and downward.

Thus, by the time it reached Florida, the Saharan air was diluted.
