Expect a hot start to May, as temperatures are predicted to climb into the low 90s in some areas today.

South Florida's Thursday forecast calls for mostly sunny skies with afternoon highs in the upper 80s and low 90s, overnight readings in the mid 70s and a 20 percent chance of rain.

It also should be breezy. Because of the winds, there is a high risk of rip currents at the beaches, particularly in Palm Beach County.

Friday's forecast is similar.

The heat is the result of strong high pressure over the Atlantic, and the same basic pattern is expected to persist through early next week.

Central Florida's Thursday forecast: Partly sunny and breezy with highs in the low 90s, lows in the low 70s and a 60 percent chance of rain.

Deadly April tornadoes: From weather expert Jim Lushine:

This week's massive tornado outbreak in the Southeast, causing a tragic number of deaths, confirms that April is the deadliest month for tornadoes in the United States.

This is despite the fact that both May and June actually experience more tornadoes.

In general, tornado deaths have decreased markedly in recent decades. Yet in April 2011, almost 550 people died from twisters, mostly in Alabama and Missouri. And that was despite improved technology and communication.

Fortunately for South Florida, the most active portion of the spring tornado season has passed with no significant events.

Tornadoes occur most frequently during our rainy season, but most are quite weak.

Tropical storms and hurricanes can produce tornadoes. Last June, the outer bands of Tropical Storm Andrea spawned nine tornadoes in Florida, three of which were in Palm Beach and Broward Counties.
