It’s been hotter this June in Alaska than in the Rock Hill area, but that’s about to change.
High pressure will build across the eastern United States over the next few days, producing several days of 90-degree weather.
“A rather abrupt pattern change will take place over the area during the next 24 to 30 hours,” Justin Lane of the National Weather Service office in Greer said Saturday.
A large area of low pressure has hovered over the East for the past week to 10 days, producing several periods of rainy weather and below-average temperatures. But high pressure will take control, Lane said, limiting precipitation to the mountains and causing temperatures to climb.
Never miss a local story.
While Fairbanks, Alaska, hit 90 degrees Friday, the Rock Hill area is still awaiting its first 90-degree day. The warmest reading so far this year was 89 degrees, reached on May 16 and June 3. Rock Hill typically gets about 40 days of 90 or warmer each year. Some of those are forecast over the next week, with the Weather Service predicting a high of 90 on Monday and 91 on Tuesday, Wednesday and Thursday. Humidity levels are expected to remain low into the early part of the week but climb by midweek.
Weather Service meteorologist Danny Gant said the pattern is forecast to change by Thursday or Friday, as humidity levels climb, a weak cold front approaches from the northwest, and the atmosphere gets a bit more unstable.
“This pattern will favor improved chances for showers and thunderstorms by late in the week,” Gant said.
