Pittsburgh will see extreme heat week of July 4th. How hot will it get?

• A heat wave is bringing record-breaking temperatures to the Midwest and Eastern U.S.
• Pittsburgh is expected to see temperatures reach 100 degrees Fahrenheit ahead of the July 4th holiday.
• Temperatures and high humidity will create an extreme heat risk, increasing the danger of heat exhaustion or stroke.

As a heat wave brings record-breaking temperatures to much of the U.S. ahead of America's 250th anniversary, the heat in Pittsburgh is expected to hit triple digits, with humidity likely to make it feel even hotter.

Extreme temperatures struck the Midwest and Eastern U.S. over the June 27-28 weekend and are expected to last at least through July 4, according to NWS. In Western Pennsylvania, that means heat in the upper 90s with high humidity is expected throughout the week, with the possibility of temperatures hitting 100 degrees Fahrenheit in Pittsburgh just two days out from Independence Day.

Here's what to expect from the weather this week.

How hot will it be in Pittsburgh on July 4th?

The heat Pittsburgh is expected to climb over the next few days and peak on Thursday, July 2 at 100 degrees, according to the National Weather Service. Here's an overview of temperatures this week:

• Monday, June 29: High of 90, low of 71
• Tuesday, June 30: High of 94, low of 76
• Wednesday, July 1: High of 98, low of 76
• Thursday, July 2: High of 100, low of 77

How hot will it feel in Pittsburgh during heat wave?

As a heat wave sweeps across much of the U.S. this week, Pittsburgh is also expected to see extreme temperatures.

Ahead of and through Independence Day, the Steel City is likely to see an extreme heat risk, NWS reported. Significant risk indicates heat exhaustion or heat stroke is likely with prolonged outdoor exposure, while extreme risk means that the weather is dangerously hot and could quickly result in heat exhaustion or heat stroke.

Excessive heat hazards are calculated based on factors like the highest maximum temperatures in a given area and the effects of humidity. Temperatures over 99 can cause heat to begin to build in the body, and higher levels of humidity make it harder for sweat to evaporate efficiently and can lead to overheating.

Will it rain in Pittsburgh on July 4?

The days leading up to Independence Day are likely to be sunny and hot with next to no chance of rain, according to NWS. The possibility of storms will jump on Independence Day. Here's what you'll likely see over the next few days:
