Hundreds of millions of people remain under sweltering conditions as a heat dome sends temperatures soaring 10 to 20 degrees above average across much of the eastern United States. Afternoon high temperatures in the 90s and lower 100s, combined with AccuWeather RealFeel® Temperatures near 110 degrees, will create dangerous conditions for anyone spending extended time outdoors today for the holiday.
AccuWeather expert meteorologists are tracking several threats today that could impact outdoor events in major cities:
- An all-time high temperature record could fall in Washington, D.C., which is forecast to reach 101 degrees. The current record is 100 degrees, set in 1919.
- A new high-risk area for severe thunderstorms along the I-95 corridor from Philadelphia to Washington, D.C. with widespread damaging wind gusts from 60 – 70 miles per hour are expected
- The risk of severe thunderstorms extends up the I-95 corridor into New York City
With as many as 2 million people estimated to gather on the National Mall in D.C. for America250 festivities, likely all day long in the extreme heat, people need to do more than just find the perfect spot to watch the fireworks.
“For the historic celebration, dangerous, and potentially historic, heat is expected in the nation’s capital,” said AccuWeather Expert Meteorologist Dan Pydynowski. “People planning to spend hours outdoors should drink plenty of water, seek shade or air conditioning whenever possible, and know the warning signs of heat-related illness. In addition, have a safe place in mind to be able to seek shelter from any storms that could form in the area.”
Other Holiday Impacts AccuWeather Expert Meteorologists are Tracking
- Thunderstorms capable of producing damaging wind gusts, frequent lightning and localized severe weather expected from Wyoming to the Midwest
- Lightning and heavy rain are capable of delaying fireworks displays and other America250 celebrations in any area where storms are in the forecast
- The largest area of favorable fireworks viewing extends from the Pacific Coast to the Rocky Mountains
- Wildfire smoke and elevated fire danger continue across portions of the West
Heat Safety Tips to Stay Safe
- Anyone celebrating outdoors should plan ahead to reduce the risk of heat-related illness
- Drink water frequently throughout the day, even if you don’t feel thirsty
- Schedule outdoor activities during the morning or evening whenever possible and take frequent breaks in the shade or air conditioning
- Wear lightweight, light-colored clothing
- Check on older adults, young children and people with underlying health conditions
- Never leave children or pets unattended in a vehicle
- Monitor AccuWeather RealFeel® Temperatures and local weather conditions before heading outside
Looking Ahead to Next Week: Heat Dome in the West
AccuWeather expert meteorologists say a new heat dome will develop from the Rockies to the Pacific Coast next week and is expected to bring the season’s highest temperatures so far across parts of the region. Temperatures across the West are forecast to climb to 10-20 degrees above the 30-year historical average by mid-July.
Highs may approach 100 degrees Fahrenheit in Denver by next weekend, while Salt Lake City is forecast to reach the low 100s during the following week. The new heat may exceed temperatures recorded during spring heat waves in Phoenix, Las Vegas and Palm Springs, California.
