When will it rain again?

A stubborn high pressure system is baking Palm Beach County and giving little hope that there will be significant rainfall in the near future.

The National Weather Service in Miami is predicting a 10 percent chance of rain for today and tomorrow, increasing to 20 percent over the weekend.

But meteorologist Robert Garcia said don’t get your hopes up for widespread showers.

While there may be a few pop-up storms in the western reaches of Palm Beach County, coastal areas are likely to remain dry.

“It’s just sitting there and beating us down,” said Garcia about the high pressure system that helped temperatures climb to a record-tying high of 95 degrees on Wednesday. “We can get these dry spells especially when we have Saharan dust layers.”

Garcia said the Saharan dust, which has been working to dry out the upper reaches of the atmosphere, is starting to disperse, but that those layers remain parched.

While the surface is hot and humid with a heat index of up to 107 in interior reaches of the county, the upper atmosphere must also be moist to help thunderstorms form.

“It’s shifted from worrying about lightning to worrying about people getting sick from the heat,” Garcia said.

Palm Beach County has seen nearly no significant rain this month, with Palm Beach International Airport recording just .04 inches – 1.26 inches below what’s normal.

The high today is forecast to reach 93 degrees, which likely won’t hit the record of 97 set in 1980.

Tomorrow’s high should also reach 93.
