Ridge in jet stream brings area warmth, but threat of showers

Temperatures in northcentral Pennsylvania climbed well above normal levels Sunday, welcoming in a reprieve from weeks of colder weather, according to the National Weather Service in State College.

The high temperature recorded at the Williamsport Regional Airport Sunday was 66. That’s well above the normal mid-50 degrees for this time of year, said weather service meteorologist Barry Lambert.

He said a ridge in the jet stream is ushering warmer conditions into the northeast.

“We haven’t seen that in the last several weeks or months,” he said of the weather pattern.

Above-average temperatures will continue through Thursday, with a potential high “tickleing 80” on Wednesday, according to Lambert.

After that, however, high temperatures will be more spring-like.

“We’re getting back to near normal temperatures. We’ve been below normal so persistently,” he said.

The potential for rain showers each day through Saturday with related cloud cover may help ease concerns about brush and wildfires created by warmer, drier weather, Lambert said.

He said those who conduct outdoor burning of any kind still should be cautious.

“It’s something to be aware of, especially on the breezy days,” he said.

Today’s high should be around 68 with a chance of an evening shower or thunderstorm.

Tuesday’s high is expected to be near 74 with a chance of rain. Tuesday evening’s low is forecast to be 54 with a chance of rain showers.

Wednesday morning could bring more showers with afternoon temperatures near 80.

Lambert said the long-term outlook calls for above normal temperatures with above normal precipitation amounts.
