RALEIGH, N.C. — Sunday's overcast skies gave way to heavy downpours in some places by evening, and a line of thunderstorms drenched the Sandhills and Cumberland County.

"These storms are not likely to move very quickly and could produce localized heavy downpours," said WRAL meteorologist Aimee Wilmoth. "Some isolated flooding is not out of the question."

The National Weather Service issued a Flash Flood Watch for dozens of counties, primarily in the western part of the state, into the early hours of Monday.

Cobalt Creek, near the stadium of the Holly Springs Salamanders, surged over its banks Sunday afternoon, while in the eastern part of Wake County no rain was recorded. In Princeton in Johnston County, residents saw about a half inch of rain fall in just a short time.

That pattern of patchy storms – where some places see heavy rain while others get none – sets up a pattern that will repeat on Monday.

"It will be a bit cooler on Monday," Wilmoth said, with the forecast high only reaching about 86 degrees.

"We'll see scattered showers and perhaps a storm or two in spots, mainly after midday. Again, some of the storm cells could produce localized heavy rain," she said.

Rain chances rise again on Monday, especially in the late afternoon.

The greatest chance for rain comes during the evening rush hour on Monday, when there is a 65 percent chance for some showers.

Heat, humidity and the chance for late-day thunderstorms continue through at least Thursday, although none of those days will be a complete washout, Wilmoth said.
