Forecasters said west winds are pushing the west coast sea breeze fronts to the center of the state and the east coast where storms could erupt along the boundary.

Some storms are already popping up in Jupiter and areas of the Treasure Coast.

Isolated strong wind gusts and small hail are possible.

Previous story: Showers and thunderstorms are expected to erupt after 2 p.m. today as temperatures near 90 degrees.

But it’s Friday that forecasters are pointing to as the  more severe weather day as another mass of unstable air  moves in from the Gulf of Mexico.

The Storm Prediction Center has all of the Florida peninsula in a marginal risk for severe weather Friday, with the Panhandle at a slight level. Marginal is the lowest level on a five tier threat scale, with slight as the second level.

“Today’s hazards are a high risk of lightning,” said Barry Baxter, a meteorologist with the National Weather Service in Miami. “No threat of tornadoes, a slight risk of hail and flooding is a concern again.”

West Palm Beach saw the highest rainfall total on record for Wednesday’s date, according to the National Weather Service in Miami.

A total of 2.32 inches was recorded Wednesday night at Palm Beach International Airport. The previous record was 1.79 inches in 1911.

Radar estimates show that up to 5 inches fell in western Boynton Beach, the weather service said.

Baxter said three-day rain totals for central and coastal Palm Beach County are between six to eight inches. Another one to two inches is expected through Saturday.

Friday’s storms are expected to begin in the late morning and early afternoon as the upper-level disturbance moves into Florida. More of the same is expected for Saturday as South Florida remains in the marginal threat category for severe weather.

On Sunday, a cold front approaches the state and behind it is some drier air.

 

So it’s been rainy, but at least we’re not Washington D.C.

 

Previous story: Thunderstorms will persist through this morning before breaking for several hours and igniting again.

Moist warm air is keeping the atmosphere unstable, but strong upper level winds are adding to the tumult. National Weather Service forecasters said the biggest concern is frequent lightning strikes, but localized flooding is also possible.

About 3,000 Palm Beach County residents are without power this morning, according to FPL.

Lightning has already killed two Palm Beach County residents this year. Go inside if thunder is heard.

Rain chances today remain high at 70 percent, reducing to 40 percent overnight.

Storms will continue into Friday, mainly after 9 a.m., with a 40 percent chance of rain during the day and into evening.

With afternoon showers, Palm Beach County and the Treasure Coast should brace for more soaking rains.
