Good morning, Maryland!
After another hot Independence Day, the weather pattern remains active across the Mid-Atlantic. Sunday brings another warm, humid day with sunshine to start, followed by scattered afternoon and evening thunderstorms. While temperatures will be a few degrees lower than Saturday, it will still feel uncomfortable outside, especially away from the mountains and beaches.
Not everyone will see rain, but any storm that develops could produce heavy downpours, gusty winds, dangerous lightning, and localized flooding. The National Weather Service continues to highlight the potential for locally strong storms across portions of Maryland during the afternoon and evening.
