Record-breaking heat has settled across the nation this Fourth of July.

It's so hot, some areas are canceling holiday fireworks as bone dry conditions raise more concerns about wildfires.

In a steamy south Florida, display workers were still preparing to celebrate the Fourth of July with fireworks. But the blazing sun has canceled many pyrotechnic displays in parts of Alabama, Texas and Arizona.

"Please do not purchase, do not sell and do not use fireworks," said New Mexico Gov. Susana Martinez,.

Gov. Martinez is urging her constituents not to play with fireworks during wildfires, like the one monster fire that's still burning near Los Alamos.

"It's like an oven out here. Seriously," a woman said.

Weekend temperatures topped 100 degrees in Phoenix, Ariz., and in some parts of California, where many people found comfort at the beach.

"It's supposed to be around 100 today, so figured we would just get away from the heat and come down," a beachgoer said.

There were misting stations set up at a rib festival just outside Chicago. Still, some festival attendees had to be treated for heat-related illnesses.

Temperatures swelled in the mid-90s, however 94 degrees felt more like 102.

"Just not used to this humidity. We're taking care of them They're fine as of right now," said Jerry Kochurka, chairman of the 2011 Ribfest.

The heat is keeping one emergency team in Oklahoma busy. They answered more than a dozen calls in one day.

"It can affect people of all ages and there's no bounds as to what they are doing outside," said medical team worker Mike Roy.

In Washington State, residents were celebrating the summer's hottest holiday on skiis.

"We have seen some bikinis, lot of board shorts, a lot of tank tops and sunglasses. People are having a great time," said Tiana Engler, marketing director of Crystal Mountain.

Meanwhile, fierce thunderstorms also hit the Midwest this weekend, killing an 11-year-old girl and sending nearly 40 people to the hospital.
