Heat warnings centered on Missouri covering parts of 13 states in the Central and Southern Plains in the mid-south. There are more warnings in the greater part of the Northeast Urban Corridor. Excessive heat warnings were also activated on Friday for 10 million people in the southwestern desert.
Boston and New York City have changed their triathlon plans for the weekend. In Boston, it was like that postponed until AugustNew York City has been shortened by almost half.
far south, Washington, DC, still under major announcement Emergency heat until Monday. City pools will open late, and shelters and cooling centers will also be available.
In Texas and much of the southern plains, farmers and ranchers suffer from scorched fields and stressed livestock. Persistent hot and dry conditions are unheard of in parts of the region.
Dozens of record highs have already been breached in the past several days, and about three dozen could be threatened over the weekend. Numerous records of warm bottoms are also likely.
An excessive heat warning was issued for much of the desert southwest on Friday, including Phoenix, Las Vegas and Palm Springs, California.
“Normal high temperatures are likely to well exceed 110 to 115 degrees today in Phoenix and all low desert communities across the region,” the weather service wrote there.
This follows a number of record highs on Thursday. They include Barstow, California at 112; Bishop, CA, at 106; and Desert Rock, Nevada, at 108. A record high of a minimum of 90 was also set in Las Vegas. in Needles, California Overnight low 95 was great on Wednesday.
Friday will likely be the last in this current wave of excessive heat in the region, as temperatures then stabilize towards normal levels near 100. Humidity associated with the summer monsoon — a shift in winds that brings rain to the region — is set to increase , which helps build clouds and lower temperatures.
Across the southern plains and into the mid-south, temperatures of 100 or higher have been the norm for weeks. Long-term drought and the spread of a quick dry It just amplifies the feedback loop between hot and dry conditions.
A slew of record highs fell across Texas on Thursday, including San Antonio, where it reached 102. That was the fifth record high there this month, above eight records in June and eight in May. The city now had 42 days at 100 or more in 2022, compared to an average of 19 days for the entire summer.
San Antonio saw 17 days of triple-digit heat in June. Rule two.
Additional record highs on Thursday included Houston (at Hobby Airport) with 100, Austin at 103, and College Station at 105. Several locations in Texas, such as Abilene and Dallas, also recorded record minimums for this date.
Mercury rises in the mid-Atlantic and Northeast
While the Northeast has avoided the sweltering heat so far this summer, the area sees its warmest weather of the season so far over the weekend.
Boston, Providence and Hartford, as well as coastal areas such as Cape Cod, are subject to heat warnings on Saturday and Sunday. Temperatures inland are expected to reach record highs in the mid-1990s, while cooler locations near the beach also rise to near 90 or higher.
It’s a similar story in New York City and Philadelphia, where a heat warning runs Friday through Sunday, and every day you should see readings that reach at least into the mid-90s and higher.
“There will be a chance that a few spots will reach warming warnings on Sunday, and that will need to be monitored for subsequent forecasts,” NWS New York City wrote.
Metropolitan New Jersey and parts of New York City are most at risk of reaching heat warning standards, which include heat index values close to 110. Newark, in the middle of a major urban heat island, hit 100-fold this week.
DC heat wave: It could hit 100 for the first time in six years on Sunday
From the metropolitan areas and Baltimore to Richmond, temperatures will rise in the mid-90s on Friday, with the 90s hitting nearly 100 this weekend. Additional heat alerts seem like a good bet for these areas.
There are many record highs ahead before a cold front brings a pause in harsh temperatures early next week. Sunday will probably be the hottest stretching day, and many records could fall.
In addition to high temperatures during the day, rest at night will be minimal. Urban temperatures may not fall much lower than the 80’s, while others fall into the deep 70s.
Northwest heat returns next week
So far, this summer has been relatively mild in most of the Pacific Northwest. But rising pressure in the region from the Gulf of Alaska early next week is setting the stage for the hottest weather of the year yet.
“Western Washington will experience an extended period of much higher-than-normal temperatures and dry conditions over the long term,” NWS Seattle wrote.
Scientists found that a heatwave in the Pacific Northwest in 2021 was ‘virtually impossible’ without climate change
Hot weather takes place on Mondays and lasts most of the work week. With temperatures in the 90s during the days, heat alerts may be triggered in parts of the area as forecasts approach.
A large “thermal dome” of high pressure has been installed across the southern United States for weeks. At times, it expanded to reach the West Coast and East Coast.
Drowning air at high pressure tends to impede the development of clouds and thunderstorms, increasing the amount of sunshine in summer. Just over half of the Lower 48 is under drought conditions, according to a U.S. Drought Watch update released Thursday. Nearly 70 percent were rated at least as abnormally dry.
Dehydration and high stress tend to go hand in hand. The extended survival of the thermal dome helped the drought and rising temperatures persist.
Britain’s miraculous heat broke records. Here’s what happened.
Human-driven climate change is also amplifying heat. Temperatures tend to be a few degrees warmer than you would have without them – This has been confirmed in this summer’s weather in the United States and around the world.
