Boston, MA – An extreme heat wave is sweeping across New England, bringing soaring temperatures that are already reaching the upper 90s. This intense heat is expected to persist through midweek, prompting officials to issue heat emergencies and air quality alerts throughout the region.
High pressure and a southerly airflow are primarily responsible for the prolonged heat, contributing to an influx of warm air. Boston has declared a heat emergency through Wednesday, as the temperature is projected to peak in the low to mid-90s, with some areas experiencing heat indices in the upper 90s. Logan Airport recently exceeded 90 degrees, effectively marking the onset of an official heat wave for this summer.
In addition to heat advisories issued for parts of New Hampshire through Tuesday, air quality alerts have been activated for most of Southern New England. Residents are urged to stay hydrated, limit outdoor activities, and check in on those who may be more vulnerable to heat-related illnesses, such as the elderly and young children.
Despite the heat, there is a notable difference this time around: the dew points and humidity levels are lower than those seen in previous heat waves, making it feel humid but less oppressive. Dew points are forecasted to vary between the low to mid-60s across the area, in contrast to the high humidity often associated with extreme heat. However, the combination of heat and low humidity raises concerns about potential drought conditions due to the extended dry weather.
On Tuesday night, temperatures are expected to drop to the upper 60s to low 70s as residents brace for another day of heat on Wednesday. Light winds and mostly sunny skies are anticipated, though some haze from Canadian wildfires may be present in the air. While temperatures at the immediate coast will remain slightly cooler, in the upper 80s, inland areas are set to experience consistently high temperatures hovering around 90 degrees.
Per forecasts, record daily high temperatures may be challenged in various locations, including Burlington, Vermont, and Syracuse, New York. As the heat plagues the region, it is crucial for individuals to recognize the symptoms of heat-related illnesses, which may include heavy sweating, clammy skin, dizziness, nausea, and muscle aches.
An impending cold front is expected to approach late Wednesday into Thursday, bringing some much-needed relief from the oppressive heat along with possible showers. Following the frontal system, temperatures are forecasted to return to near-average levels for mid-August by the weekend, providing respite from the extreme conditions.
In light of the heat wave’s severity, the public is reminded that children and pets should never be left unattended in vehicles, even for brief moments. As people seek ways to beat the heat, staying informed and taking safety precautions can help mitigate the risks associated with such extreme weather.
