With temperatures warming Sunday and today, the reality of fall will return Tuesday when they drop below normal.
Today, temperatures are forecast to reach 61 degrees, said Accuweather meteorologist Alan Reppert in State College.
The low is expected to dip down to 40 degrees tonight. Rain also might move into the area, with a predicted 0.25 to 0.50-inch expected.

So far this year, precipitation has been below normal. The average rainfall for the year up to this point is 35.84 inches, but the area only has received 29.99 inches.
However, Reppert said it is "not really that significant" a difference.
Continuing through the week, Tuesday should be more than 10 degrees cooler than today, with a high of 46 degrees. The overnight low will drop to 30 degrees.
On Wednesday, the same temperatures are expected: 46 degrees for the high, 30 degrees for the low.
Thursday's high is expected to reach 48 degrees with a low of 32 degrees.
On Friday, a high of 49 degrees is expected, with a low of 29 degrees.
Saturday's high is expected to be near 50, with a low around 34.
On Sunday, a high near 51 degrees is expected.
While air pressure from the south brought the warmer weather and sunshine this past weekend, a cold front from the northwest will bring the colder air.
The average highs for mid-November are in the lower 50s, while the lows are in the mid-30s.
"It will be lower than normal (this week)," Reppert said.
Winter is expected to be near normal with snowfall, and temperatures near to slightly below normal, he said.
