The high pressure system keeping the rain at bay in South Florida and the temperatures on the high side will start to slide northeast over the weekend, but warm days and partly sunny skies should persist through Sunday evening.
Arlena Moses, a meteorologist with the National Weather Service in Miami, said moisture should begin moving into South Florida tomorrow, leading to an isolated shower on Saturday and Sunday.
“The front is trying to get to South Florida, but it will be fairly weak and we don’t expect anything in the way of severe weather,” Moses said. “It will be a summer-like pattern with scattered showers mostly in the interior sections.”
A concern for rip currents will likely remain through the weekend, especially as spring break means more visitors to South Florida beaches. There is a high risk through Friday, but Moses said a moderate risk will probably be extended through Saturday and Sunday.
Winds will start to calm Saturday, but are still expected to blow at a sustained 15 mph with gusts to 25 mph.
Temperatures are forecast to remain above normal near 80 degrees. The normal daytime high for mid-March is 78 degrees with a low of 62.
“The concern through the weekend will continue to be hazardous marine conditions on the Atlantic side and then introducing a few afternoon showers,” Moses said.
After the front moves through Sunday, the chances for storms increase into early next week.
While Florida and much of the northeast has enjoyed the swath of high pressure and warm temperatures, parts of the south central U.S. have experienced a deluge of rain that has caused flooding and evacuations in Louisiana.
The National Weather Service in Shreveport called the result of 20 inches of rain in some areas a historic flash flooding event.
