Blustery day before cool front this weekend

A blustery day with wind gusts topping 30 mph will turn into a mixed bag for the weekend, including some sun and a Sunday cool front with a near guarantee of rain.

Sustained east winds this morning at Palm Beach International Airport are measuring upwards of 20 mph with gusts to 31 mph.

The wind, which has triggered a wind advisory for Lake Okeechobee, rip current warnings along the Atlantic beaches and a small craft advisory, is a function of a high pressure system moving into South Florida rubbing up against a stationary boundary stretching from the Bahamas into the Gulf of Mexico.

“Wind speeds will only increase as we go through today,” said National Weather Service meteorologists in their  morning forecast. “Temperatures are quite mild this  morning, being regulated off the stiff breeze off the relatively warm Atlantic waters.”

Today’s hazards

Saturday’s forecast is for mostly cloudy skies, a high temperature of 75 degrees, with breezy conditions continuing as a low pressure system begins to dig into the Mississippi Valley.

That low will increase winds out of the south, bringing more warm, tropical air into South Florida.

By Sunday, an area of low pressure expected to form in the Gulf of Mexico will begin to move through North  Florida, trailing a cool front that will increase the chances for rain Sunday between 30 and 60 percent for the day and up to 80 percent overnight.

A cloudy day Sunday will decrease the chances for thunderstorms ahead of the front as daytime heating will muted, but there is a low chance of thunderstorms in the forecast.

The cool front will whip winds back out of the  north, pulling in colder air that will make its mark Monday night with lows in the mid-50s and a high Tuesday in the upper 60s.
