2-3 inches is expected with isolated higher amounts especially along and east of I-95. It won't rain everywhere all the time, but prepare for pockets of heavy rain and downpours, which could lead to flash flooding. The National Weather Service has already posted the first warning of the day for Frederick County, MD and western Carroll County. Spotty showers are anticipated into the weekend, but it shouldn't be as widespread or as heavy as today. We'll keep you posted.
