The FOX Forecast Center is tracking who could see potentially record-setting warmth for Independence Day, who will be dodging rain and who could face travel impacts for America’s 250th birthday.
Blistering heat across Central and Eastern US
Most of this week will feature extreme warmth, leaving many to wonder if the heat will spoil Fourth of July plans.
Right now, it is becoming clear that there will be little relief come Saturday, the FOX Forecast Center said.
While the record-breaking temperatures may take a small step back, the massive scope of the heat dome will remain locked in as over 230 million Americans could feel the impacts leading into the holiday.

The heat dome fueling the extreme temperatures acts like a giant lid on the atmosphere, trapping hot air on the ground, while underneath this hot airmass, humid air will be brought in from the Gulf of America.
For perspective, more than 194 million Americans are expected to experience temperatures above 90 degrees this Fourth of July, with over 120 million facing a heat index above 100 degrees.
Additionally, at least 30 potential record highs linger for cities such as Washington, D.C.; Richmond, Virginia; Raleigh, North Carolina; and Charlotte, North Carolina.

That said, even areas outside the Eastern Seaboard will still be slightly above average come this 4th of July.
The Midwest, Plains and Deep South will all face the 90s, though this is more typical for these regions for this time of the year.
The pop-up thunderstorm threat
Classic summertime pop-up showers could potentially put a hold on beach trips, barbecues and other outdoor activities this Fourth of July.

Traveling for the holiday?
