Those with outdoor plans this weekend take heed: It’s about to warm up in a big way.

A heat wave that will produce temperatures not seen since last summer is on the horizon.

We can expect a surge of heat here in the northeast, according to Paul Walker, a senior meteorologist with AccuWeather.

“Things are going to be getting hot this weekend,” Walker said. “There’s a warm front moving through the area today, which could bring a couple of thunderstorms to the area mainly this afternoon.”

Walker said the warm front could bring some torrential downpours, hail, even an isolated tornado, with tonight’s low only expected to be 67, an uncomfortable night for people who don’t have their air conditioners in yet.

He said temperatures are expected to soar tomorrow, when it reaches 93, a far cry from the normal mid-70s we usually see this time of year.

That, Walker said, could result in record levels in some portions of the eastern part of the state.

“We’re up near record levels in many places in east,” he said. “It’s also going to be a humid day.”

Walker said we can expect 69 for a low tomorrow night, and added the heat and humidity continues into Sunday, with a high near 90.

“There may be some isolated thunderstorms (Sunday) afternoon, (which) could trim the heat in some places,” he said. “A cold front comes through Sunday night; early next week is going to be cooler and less humid.”

Walker said highs are only expected to hit 72 on Monday and 69 on Tuesday.

“Typical spring, big temperatures, but the heat doesn’t usually stay around long in the spring,” he said. “But, we do get a couple days where it can get real hot, but then return to normal when we get these temperature swings this time of year.”

Walker said it’s important to check on the elderly to make sure they’re safe in the heat.

“Stay hydrated; drink plenty of water if you have to be outdoors,” he said. “Take breaks when working outdoors.”

For those who choose to head for cooler climates, Walker offered a few pointers.

“If you decide to go down to the local pool or lake, be cautious going into the water,” he said. “With the big temperature change, (the water is) still quite chilly; be cautious going into the water for the big temperature change.”
