Soggy air will cling to South Florida through the weekend, but a shift in winds may mean a drier coast.


The National Weather Service in Miami expects a south to southeast flow to move in Saturday, which should push daily showers and thunderstorms inland toward Lake Okeechobee.


Despite a possible respite in afternoon showers, meteorologists are calling for rain accumulations of up to 2 inches in Palm Beach County through Sunday.


A “reasonable worst-case scenario” could mean up to 3 inches with some localized flooding.


“There is a 100 percent chance of rainfall exceeding 1 inch,” said NWS meteorologist Ariel Cohen. “Combined with recent rainfall rates over the past few days, it won’t take a whole lot to support flooding, particularly over urban and low-lying areas.”


Saturday’s forecast calls for a 40 percent of chance of rain in West Palm Beach, decreasing to 30 percent Saturday night.


Sunday is expected to be mostly sunny with a 30 percent chance of showers in the evening.


Both days will be seasonably hot with daytime highs near 90 degrees and overnight lows in the upper 70s.


Through Wednesday, coastal Palm Beach County has had 6 inches of rain this month, which is 2.5 inches more than normal, according to the South Florida Water Management District.


Borward and Miami-Dade counties are even more saturated with 7 and 6.5 inches of rain this month. That’s nearly 4 and 3 inches above normal, respectively.


The official gauge at Palm Beach International Airport had registered 8.95 inches of rain this month through Wednesday. That’s a whopping 5.57 inches above normal.


Cohen said the biggest concern with storms over the weekend is lightning with a slight risk of flooding.


“We are expecting the beginning of a transition where the focus of activity will transition to the interior section of the state,” Cohen said. “It will be gradual, but the overall background flow going up several thousand will change to a more east to west direction.”


The persistent west to southwest winds the past week have resulted in showers erupting along the east coast.
