Raleigh, N.C. — An upper-level disturbance has brought rain to the southern half of the WRAL viewing area and a few trailed up into the Triangle later Sunday.

Two storms combined over Wake and Durham counties and sparked a few lightning strikes on Sunday evening. The rest of the evening will be mild but continues to have the potential for a few storms, WRAL meteorologist Kim Deaner said.

Earlier, the disturbance dumped steady and sometimes heavy rain as it swept east from around Charlotte across the Sandhills to coastal counties. The storms were strong early, prompting a flash-flood warning for Union County.

Highs on Sunday reached into the mid to upper 80s, and lows were expected to drop into the mid to upper 60s overnight.

Drier and warmer conditions will prevail through the middle of the work week. Monday will be partly cloudy, and temperatures will rise into the low 90s by Tuesday.

The threat of rain, though, returns in the later portion of the week, when Tropical Storm Fay might affect North Carolina.

“We do expect rainfall by the end the week from this,” Maze said.
