Raleigh, N.C. — An unsettled weather pattern that is likely to produce spotty afternoon thunderstorms and hot weather will stay put throughout the work week across central North Carolina, WRAL meteorologist Aimee Wilmoth said. 

High temperatures will climb back into the mid-90s on Monday and will creep toward the 100-degree mark on Tuesday as a ridge of high pressure inches toward Tennessee. Low temperatures will hover in the mid-70s throughout the week.

"We'll see some storms flowing into the area from our north and west over the next couple of days," Wilmoth said. "We'll be heating up as well to along with intense humidity."

Any storms that form in the next several days could become severe and contain high winds, hail, cloud-to-ground lightning and locally heavy rain. 

"We're looking at a 40 to 50 percent chance of storms Monday afternoon and evening," Wilmoth said. "We're not looking at any widespread severe weather, but it will certainly be unsettled."

Scattered storms fired south of the Triangle Sunday afternoon, moving across parts of Wake, Johnston, Lee, Moore, Cumberland, Wayne and Duplin counties between 3 and 8 p.m. The slow-moving storms were packed with cloud-to-ground lightning and dumped heavy rain. 

On Saturday, similar storms sparked at least one house fire.

Authorities said lightning might have been responsible for a house fire at 1801 Wills Ave. in the Five Points area of Raleigh and did start a fire at 559 Jamestown Road in Pittsboro. No injuries were reported.
