As Memorial Day kicks off the unofficial start of summer, you can expect a usual summertime weather pattern for your trips to the lake, beach or mountains.

That means warm temperatures, high humidity and a good chance of some afternoon or evening thunderstorms.

How much of a chance? Depends on where you are, but the good news is most of them will be isolated and should move in and out quickly.

“They should be more of the pop-up variety in the afternoons and into the evenings, “ said Robert Garcia, a forecaster with the National Weather Service office in Peachtree City. “Right now, Memorial Day looks like a lower chance.”

Today, as most people hit the highways, there is a 40 percent chance of isolated storms and showers for your drive with a sultry high temperature of 86.

Saturday, the chance of a storm is about the same, with slightly cooler temps and a high of 81. That 40 percent chance of storms continues Sunday with a high of 84.

The chance of storms decreases to 30 percent for Memorial Day on Monday with a high of 83.

After that, the week ahead looks dry and hot, with daytime highs perhaps touching 90 degrees by Wednesday.

Visitors to Lake Lanier this holiday will find the lake full for the first time in five years, the lake level reaching 1,070.80 feet above sea level on Thursday.
