While Father's Day saw temperatures in the mid 70s Sunday, the week is expected to get progressively hotter with summer starting this week.
The area could see temperatures in the record highs as it's expected to be above 90 degrees Wednesday for the start of summer, which officially comes in at 7:09 p.m.
"It's going to warm up the second part of the week," said National Weather Service Meteorologist Elyse Colbert, of State College. "It looks like it's going to be a nice stretch of warmer weather."
Chris Laylon, of Montoursville, and his 5-year-old dog, Ben, paddle into the Muncy Boat Access. Laylon, his wife, children and dog took advantage of the warm weather Sunday to kayak and fish the Susquehanna River.
AccuWeather Meteorologist Brian Edwards, also of State College, said the warm temperatures would "absolutely" be a good opportunity for those around the area to open up their swimming pools and crank up their air conditioners.
But Edwards warns, thunderstorms could be a concern with high temperatures.
"The only caveat to that is with so much heat and humidity we may be able to pop in a thunderstorm," Edwards said.
Colbert noted that Wednesday could be the second day this year to reach 90 degrees. The first was in late May.
The beginning of the week won't be as nice as Wednesday, though, as rain is a possibility today.
"(Today) there's a chance of thunderstorms and showers, with a high of 73 (degrees)," Colbert said.
After Thursday, temperatures will cool off and settle in the mid 80s. Saturday also could see some type of precipitation, according to Colbert.
"There's a chance of rain showers at some point this weekend," she said.
Colbert said for the most part, the spring has been fairly average. She said no records were broken and temperatures weren't too far off the norm.
"It's been pretty normal." Colbert said. "We did have that stretch of warmer weather around Memorial Day but its been about average."
Edwards said even with a mild winter that produced less snowfall, the area isn't below normal precipitation levels.
"It's been fairly wet recently, we're not that far below normal," he said.
As far as this summer, Edwards expects a "fairly active" one with no "prolonged heat waves." He said there may be some stretches of heat but rain will cool the area down.
"In general, (the summer) looks like near normal temperatures overall. It looks like its going to be enough of a storm track ... that it will keep long-term heat out of the area," Edwards said.
