RALEIGH — Wednesday will likely be the best chance for a high-pressure system controlling weather over North Carolina this week to set a record before cooler air and possibly rain upstage it, according to forecasters.
The dates record high at RDU International Airport 98 degrees was set in 1944, and the National Weather Service said that might be eclipsed.
Forecasters expected high 90s in Wake and Johnston counties, they said, and mid-90s elsewhere.
Thursdays record is 102 degrees in the same year, but the heats influence will be waning by then, forecasters said.
Wednesday was expected to be generally clear, although isolated afternoon thunderstorms were possible. That is a regular part of forecasts when warm, moist air covers the area.
On Thursday, forecasters said they expected a 30 percent to 40 percent chance of showers in northeast sections, and that will extend to the region on Friday, through the weekend and possibly into the start of next week, they said.
