'Dangerous Heat': Brutal Heat Wave Will Scorch U.S. This Weekend Amid 'Deadly' Record-breaking Temperatures

Large parts of central and eastern U.S. have been told to prepare for a weekend of record-breaking heat, with some areas expected to experience temperatures reaching 110 degrees Fahrenheit.

The National Weather Service has warned that a large ridge of high pressure will bring "dangerous summer heat," resulting in widespread excessive heat warnings and heat advisories.

Kansas, Illinois, Oklahoma and Washington, D.C. have been warned they could see temperatures reach around 110 degrees Fahrenheit, with areas across the Plains, Midwest and East Coast also expecting temperatures of more than 100 degrees.

The Weather Channel said several cities, including Detroit and New York, could see their hottest day of the year so far during the next few days. Chicago and Philadelphia may also experience temperatures of more than 100 degrees for the first time since July 2012

Forecasters warned that there will not be much respite in the evenings either, as temperatures look set to drop to around the mid to late 70s and early 80s for most.

"Not only will afternoon temperatures and humidity be dangerously-high, but there won't be much relief at night for many," the NWS tweeted. "Record warm low temperatures are expected too, with 123 records currently forecast to be tied or broken."

Alex Sosnowski, senior meteorologist at ACCU Weather, warned that the intense humidity will pose significant health risks for those in central and eastern parts of the U.S.

"At this level, the hot July months of the past in 2012, 2011, 1991, 1980 and 1930 will be rivaled. Forecast temperatures are 10-15 degrees above average even for the middle of summer," he said.

"However, near-100-degree temperatures with high humidity is significantly different than that of the typically low humidity locations of the Southwest. Both areas are dangerous in the heat, but with the combination of vast paved areas and heavy population, the health risk is significantly higher for more people in the humid regions."

The NWS said the most dangerous times for the heat and humidity will occur from mid afternoon into the early evening. They have warned millions of residents to take precautions over the next few days in order to deal with the prolonged period of dangerously hot temperatures.

"Take extra precautions if you work or spend time outside. When possible, reschedule strenuous activities to the early morning or the late evening," the NWS said in a statement.

"Know the signs and symptoms of heat exhaustion and heat stroke. Wear light weight and loose fitting clothing. Drink plenty of water. Young children and pets should never be left unattended in a vehicle under any circumstance. This is especially true during hot weather when a car's interior can reach lethal temperatures in a matter of minutes."
