Punishing heat expands with 216 million people in America expected to endure temps of 90 or above

0

The extreme heat expanded its footprint Thursday, with heat alerts now in more locations across the mid-Atlantic, including Washington and the desert southwest, including Phoenix.

These heat alerts cover 97 million people.

When counting the number of people who will see a rise above 90 on Thursday, including those outside of heat alerts, that number rises to 216 million.

For parts of the Plains, high temperatures will rise above 100 again in cities like Dallas, Oklahoma City and Houston. Across the south, high temperatures in the upper 90s of nearly 100 degrees combined with high humidity will result in heat index values ​​of 110-115. Across the mid-Atlantic and Northeast, highs in the mid-1990s combined with high humidity will result in heat index values ​​of 98-108.

Higher temperatures will also set records. From Thursday to Saturday, it will be possible to achieve record heights for cities such as Houston, Memphis, Tennessee and San Antonio.

On Sunday, it will be possible to set several records throughout the Northeast including Washington, Philadelphia, New York and Providence, Rhode Island.

With the weekend approaching, while some areas will get a break from the heat, others, such as the Southern Plains, won’t feel comfortable anytime soon.

For the Midwest, temperatures will rise over the weekend but the trend for cooler Sundays will arrive early next week.

Across the Northeast and New England, the heat wave will continue for the next five days but will stop on Tuesday.

New York City may be facing its longest heat wave in a decade. The last time the city had seven consecutive days was in the 1990s in 2013.

Philadelphia’s temperature is expected to reach 100 degrees on Sunday (which would make a daily record high), and when combined with the high humidity, it will make it feel like 105 degrees. The last time Philadelphia scored a score of 100 was in July 2012.

Further south, for cities like Dallas, the heat will extend next week with no real end in sight.

While the combination of heat and moisture is dangerous on its own, it helps fuel life-threatening flash floods and the risk of severe thunderstorms.

Early Thursday, a small batch of thunderstorms trained over parts of northern Tennessee, including the Knoxville area, dropping 2 to 8 inches of rain in a short amount of time causing flash floods and water rescues. That group of storms is expected to move south into northern Georgia through Thursday morning, with flash flooding a concern.

In addition to the isolated flood risk from slow thunderstorms, strong to severe storms will also be possible in the next three days.

On Thursday, 26 million people are at risk of severe storms in two regions, New England and the Southeast. Cold and high winds will be the biggest risks, but an isolated hurricane cannot be ruled out.

On Friday, pockets of strong storms may affect parts of the Midwest and Northeast.

By Saturday, there could be a severe weather event for 12 million people across parts of the Great Lakes and the upper Midwest. Very large hail, large destructive winds and hurricanes will be possible.
