A cool front was crossing North Carolina Tuesday, presaging a change to weather more suitable to September.
"Today will still feel warm and humid," said WRAL meteorologist Mike Moss. "Tomorrow will be a little cooler and less humid."
Widely scattered storms and showers are possible all across central North Carolina through the day, but clearer skies will follow.
A weak high pressure system builds in Wednesday, bringing high temperatures will range through the mid- to upper-80s, with overnight lows that could dip below 60 degrees.
Moss said Tuesday's storms would be hard to pin down, either by time or geography.
"These storms are in little pockets and clusters drifting east," Moss said. "There will be wide spaces in between where some people won't see any rain."
The National Weather Service issued a severe thunderstorm warning for parts of Johnston, Nash and Wilson counties at about 11 a.m., and storms popped up early Tuesday morning over Fuquay-Varina. Both outbreaks were short-lived and no damage was reported.
At the Wake County Justice Center, workers returned after the long weekend to find that a surge, possibly from a lightning strike, had knocked out power to some of the building's electrical systems. About two-thirds of the elevators and some signage was knocked out Sunday, said Sarah Williamson, county public affairs manager. By Tuesday afternoon, most of the problems had been remedied.
