With high pressure anchored over the southeast, we may end up with 9 to 10 consecutive days with a heat advisory or warning.
In New Jersey, where historically there have been three days per year on average with a heat index above 100 degrees F, it would increase to 24 by midcentury and 49 by its end if no action is taken to stem climate change.
To talk more about this research, The Show reached out to Astrid Caldas, a senior climate scientist at the Union of Concerned Scientists, and one of the report's co-authors. It will be even warmer on Thursday and Friday, with high temperatures around 100 and heat index readings of 108 to 112 around the area.
According to National Weather Service records, the hottest months at Bellingham International Airport are July and August, with average high temperatures of 71.3 and 71.9, respectively. Those extreme conditions pose extreme health risks, according to the report.
Temperatures will feel significantly hotter for the remainder of the week. Data shows heat waves are affecting 50 major cities in the United States more frequently now than several decades ago, increasing from twice per year during the 1960s to almost six heat waves per year in the 2010s.
"We have little to no experience with "off-the-charts" heat in the USA", said Erika Spanger-Siegfried, lead climate analyst at the Union of Concerned Scientists and report co-author. While the afternoon heat will grab the headlines, the nights won't feature much of a cool down with mid to upper 70 morning temperatures.
The worst part, if you ask me, is that we won't get any relief overnight! After that, our high temperatures and heat index values soar.
UCS officials said the 90-degree heat index represents the point at which outdoor workers "generally become susceptible to heat-related illness".
Johnson urged people to restrict exposure to the heat this weekend, and to give extra attention to children, the elderly, infirm and pets - all of whom are particularly vulnerable to the heat. By the last quarter of the century, this projection rises to 155 days, more than five times the historical average of 30 days.
On some days, the conditions would be so extreme that they'd exceed the upper limit of the heat index, making it "incalculable", according to the study. (40); Avondale-Goodyear, Ariz. (38); Indio-Cathedral City; Calif. (37); Phoenix-Mesa, Ariz.
