Cooler temperatures have arrived in MA. How long will they last?
The weather has changed in Massachusetts.
After recent sweltering temperatures, the Northeast has cooled somewhat, while states such as Florida, Texas, Louisiana, Mississippi, Alabama, Tennessee, Arkansas, Missouri, Oklahoma and Kansas are battling heat waves.
Last week, tropical rainstorm Debby brought “significantly cooler and less humid” air as it swept through the Northeast, Paul Pastelok, AccuWeather’s senior long-term forecaster, said in a news release.
And even though it’s August, it looks like the cooler temperatures are here to stay for a while.
“The southward tilt of the jet stream will continue from the Midwest to the Northeast for the next week or two,” Pastelok said. “There may be brief warmings and fluctuations in humidity, but that usually happens just before a new surge of cool air is about to sweep over the region.”
Pastelok explained that if the region experiences a prolonged dip in the jet stream, as is currently the case in the Northeast, “this can easily result in temperatures that are no higher than the historical average and occasionally even lower.”
“There is a good chance that this jet stream constellation with its cool conditions will continue until the last week of August,” Pastelok added.
Is there a chance that temperatures will get warmer again?
Pastelok said that’s a possibility. He explained that toward the end of August, the jet stream pattern across the country could “flatten out,” which “should allow less intrusion of cool air from central Canada into the Northeast… In turn, some warmer air from the Plains should be able to mix eastward.”
