Two weeks of daily deluges have saturated the ground, which means the "possibility of additional flooding in the low-lying and poor drainage areas" of Palm Beach County.


Through Wednesday, coastal Palm Beach County has had 6 inches of rain this month, which is 2.5 inches more than normal.

Rain chances today are 70 percent, with a high a seasonally near-normal temperature forecast of 92 and an overnight low of 78.


Thunderstorms could be driven by cooling in the upper atmosphere.


While Friday’s forecast is expected to be a repeat of the past two weeks, there is hope for the weekend.


According to the NWS, the U.S. and European weather models are both showing a ridge of high pressure moving east, which would shift the wind flow to a more south-southeasterly direction.

A slightly drier air mass will also begin to move into South Florida.


Showers and thunderstorms will still be possible but the shift in wind direction could push the storms closer to the interior of the state and away from the coast.


Rain chances Saturday are 50 percent, reducing to 40 percent in the evening.


Sunday’s rain chances are 30 percent, reducing to 20 percent at night.
