The Memorial Day weekend kicked off with a multi-day thunderstorm and heavy rainfall system hitting the south-central part of the country, forecasters said.

Rounds of severe weather and heavy rain are expected across the Plains and parts of the south throughout the holiday weekend.

High heat, humidity, and potential severe storms expected in Orlando over the holiday weekend with heat index values reaching 100-105 next week.

South Florida faces a new storm threat Saturday with damaging winds and hail possible in Broward and Miami-Dade.

The main threats over the weekend will be damaging winds gusting up to 60 mph, large hail up to the size of quarters and heavy rainfall that could result in isolated flooding.

Another wave of severe weather is possible on Saturday after storms brought tornado warnings, at least one twister and hail to the state during the early morning hours.

A slow-moving system means rain could force those planning outdoor activities in the central and southern U.S. this holiday weekend to come up with a Plan B on one or more days.

Severe thunderstorms brought gusty winds and hail to Palm Beach County and the Treasure Coast Friday afternoon.
