Temperatures across the Richmond area will break 100 degrees on Thursday, Friday and Saturday as part of what the National Weather Service is calling a "potentially historic" heat wave.

The temperatures are being caused by a condition called a "heat dome," where high pressure in the atmosphere traps hot air, and then stays largely stagnant.

Equally concerning to NWS forecasters are overnight lows that will hover in the 70s, meaning there will be little cooling relief.

The conditions won't be unique to Richmond, as they are expected to impact large portions of the Midwest and East Coast, and comes right as many Americans head outside for the Fourth of July weekend.

"Be sure to limit outdoor activity, stay hydrated and ensure access to A/C or cooling centers," the NWS wrote.
