The area is set to experience dry, sunny weather all week long - a perfect chance to get out and enjoy the first few days of autumn.
The seasonal weather will begin getting cooler as the days grow shorter, and Mike Dangell, a meteorologist with the National Weather Service in State College, said it will keep trees on schedule for area leaf watchers.
Today will be sunny with a high near 66 degrees and a low around 38 degrees. Tuesday also will be sunny and clear with a high near 72 and a low round 40 degrees. Wednesday will be chilly, with patchy frost expected in the early morning. Daytime will be sunny with a high near 75 and low around 46. Thursday will be sunny with highs around 75 and lows around 45. Friday should be sunny with a high of 74 and low of 46. Saturday will be sunny as well, with highs around 75 and lows around 50.
A dry, warm week is not uncommon for the area in mid-September, Dangell said.
"Sometimes in September and October, we get these long stretches of dry weather like this. It's pretty common for the season, unless we get a tropical system that reaches land," he said.
This week's balmy weather comes as a result of a high pressure system heading south from Canada, Dangell said. The system is expected to hover over the area all week.
Sunday, autumn officially arrived at 4:44 p.m.
"As the season progresses, the plants start to get ready for winter, whether they die or drop their leaves. We start noticing the changes now, but the most intense leaf colors won't come until the middle of October," Dangell said.
