What a difference one week makes.

After days of unseasonable cold across the eastern half of the U.S., thanks to an appearance by the polar vortex last week, the nation's largest city will see a glimpse of summer on Friday to start the weekend.

The National Weather Service's (NWS) Weather Prediction Center (WPC) said a warm front will bring summer-like temperatures to the Ohio Valley Thursday before arriving in the Mid-Atlantic and Northeast by Friday.

SEVERE WEATHER EXPECTED FOR MILLIONS ACROSS PLAINS BEFORE STORMS TARGET MIDWEST

Temperatures in New York City will reach the 80s, and be in the mid-70s with sun Saturday, according to Fox News senior meteorologist Janice Dean.

"Then things will get cooler again, but you know what? We're going to see some warm temperatures at least for Friday, and that's the good news," Dean said Thursday on "Fox & Friends."

Warm conditions continue across the South, while the Northeast prepares for a warm-up.

Dry conditions continue across the Southeast, with high pressure dominating the region, leading to sunshine and heat.

"We're dealing with warm temperatures across the South," Dean said.

Severe storm threat shifts to Midwest

A system that moved out of the Rockies Wednesday is bringing the threat of severe weather from the central and southern Plains stretching all the way to the Midwest.

"Large hail, damaging winds, isolated tornadoes will be possible and some flash flooding," Dean said on "Fox & Friends."
