As the autumn leaves begin to peak with bright reds and yellows, Lycoming County is in for possible record-high temperatures, meteorologists say.

“We could have a couple days of record warms,” said Craig Evanego, meteorologist with the National Weather Service’s State College office.

The temperatures, that could run roughly 20 degrees higher than normal, are the result of “a nice southerly flow of warm air” resulting from a bridge of high pressure along the East Coast.

Despite the “unseasonably warm” weather, Evanego said it shouldn’t affect the changing of the leaves throughout the region. The northern mountain ranges in the state are seeing peak fall colors right now, while southern areas such as Williamsport will see their peak in a little over a week.

This week will start off with high temperatures but will cool down toward the end.

“It’s not gonna last,” Evanego said. “People should enjoy it while they can the first half of the week.”

Look for a high today of 75 degrees. Tuesday could reach a record-breaking 83 degrees. Tuesday’s record high is 82 degrees, recorded in 1964, Evanego said.

Wednesday will stay in the low 80s, with temperatures dropping to the low 70s on Thursday and eventually to the low 60s or high 50s by Saturday and Sunday.

Warm weather is not the only phenomenon for the week.

The year’s first “supermoon” of 2016 hung in the sky Sunday night. According to NASA, a moon gets this designation when it is both full and at its closest orbit to the earth.

Since the moon orbits the Earth in an elliptical pattern, during its rotation its nearest point to the Earth is 30,000 miles closer than its farthest point. Combine this close proximity with a full moon, caused when the sun, earth and moon come into perfect alignment with each other, and you get a supermoon.

This is the first of three supermoons of the year. The next two will be on Nov. 14 and Dec. 14. November’s moon will be the largest supermoon of the 21st century and it won’t be that close to the earth again until the year 2034, according to NASA.
