The National Weather Service has issued a flash flood watch in effect until midnight for Carroll County, as well north central Maryland and parts of eastern West Virginia.

“We’re expecting some storms to pop up over the area. We have been under high pressure so there isn’t much steering flow to move these storms away once they pop up,” said National Weather Service Meteorologist Cody Ledbetter. “If a storm were to pop up over anywhere in that watch area, you could have flash flooding potential if it rains long enough and hard enough.”

A watch means that the weather service expects conditions to be favorable for heavy rain to move over areas, so that there is the potential for flash flooding, according to Ledbetter.

A watch could be updated to a warning if actual conditions change such that flooding could be imminent, he said.

“A warning means we are looking at several different things on radar and we have determined a threshold has been met for an area,” Ledbetter said. “With these kinds of situations once it starts raining it can pile on pretty quick on a day like this. If we do issue a warning it’s important to remember not to drive over flooded roads things, like that.”

After a week of heat and pop-up storms, however, the weekend is looking more temperate, according to Ledbetter.

“Tomorrow you have a chance of scattered thunderstorms like today,” Ledbetter said Thursday, “but Saturday and Sunday look dry for the most part, with high temperatures in the 70s to low 80s on Sunday. So pretty nice.”
