Raleigh, N.C. — An unstable atmosphere caused by a stalled trough of low pressure resulted in some strong storms in the eastern part of the state Saturday evening, WRAL Meteorologist Kim Deaner said.

Some counties remain under a severe-thunderstorm watch until early Sunday morning.

Isolated storms that develop overnight have the potential to be severe, Deaner said. The state will have a possibility of strong storms until the early morning hours.

Hail was reported in Wayne County Saturday. Downed trees affected Robeson County.

A weak cold front is moving in from the northwest this weekend, Deaner said.

Partly to mostly sunny skies are expected Sunday, with highs in the low 90s. Drier air ahead of a high pressure system will keep down rain chances for the rest of the weekend. An isolated shower or storm will be possible near a stalled frontal boundary on the coastal southern plain.

The high-pressure system will continue to build in on Monday, keeping the Triangle hot and dry for the most of the week.
