Fall weather on the way, but tropics are brewing

National Hurricane Center

Good news for those tired of sweltering summer heat — cool air is on the way.

A low-pressure front is moving across the Southeast, the National Weather Service reports, bringing rain ahead of a mass of cold air.

A few scattered storms reached the Mississippi Coast on Tuesday to be quickly followed by cooler and drier air and clear skies.

Temperatures were expected to start falling Tuesday night, dropping all the way into the 50s by Thursday for northern parts of the coastal counties. Near the beach, temperatures will likely bottom out at about 60.

And even better news — autumn air is expected to hang around through the weekend.

The low-pressure area is expected to stall over the Southeast, keeping skies clear and temperatures cool. Friday’s high temperatures should reach only the low 80s.

After a hotter-than-normal September, this cold front will bring a few days of temperatures 5 to 10 degrees cooler than average, the weather service said.

Eye on the tropics

Some potentially not-so-good news is making its way across the Atlantic Ocean.

A broad area of low pressure labeled Invest 97 is heading toward the Caribbean Sea. It’s expected to become Tropical Storm Matthew in the next day or so, the National Hurricane Center advises.

As of 1 p.m. Tuesday, it had a 90 percent chance of formation.

It is too early to speculate on where the storm will end up and how strong it will be, though most of the models predict it will reach hurricane status.

After it becomes more developed, the forecast models will be better able to predict its movement. Some of the forecast tracks have the storm taking a northern turn up the Eastern Seaboard, but others show it moving across the Caribbean toward the Gulf of Mexico.

The Air Force Hurricane Hunters flew into the storm Tuesday afternoon.
