A taste of the dog days of summer was felt across the northeastern United States as temperatures soared 10-15 degrees Fahrenheit above normal during the second week of June. Progressively cooler conditions will spread from the Great Lakes to the coast into this weekend.
As Tropical Rainstorm Cristobal sweeps across southeastern Canada to end this week, the circulation around the storm and an area of high pressure building over south-central Canada will create a flow of air from the northwest across the Midwest, New England and the central Appalachians — and forecasters say the flow will draw in much more comfortable air.
Temperatures will be slashed by 10-20 degrees Fahrenheit in most areas with highs in the 80s to lower 90s from Wednesday being swapped with highs in the middle 60s over the mountains and in northern New England to the lower 80s along the lower mid-Atlantic coast by this weekend.
“Temperatures will swing from the near-record heat at midweek to 5-15 degrees below average for the middle of June by this weekend,” said AccuWeather Meteorologist Nicole LoBiondo.
During the middle of June, high temperatures average near 70 over northern New England to the middle 80s in the lower Chesapeake Bay region.
The cool press will come in two surges, according to AccuWeather Meteorologist Courtney Travis.
“One surge will transition from the Great Lakes to the Northeast into Thursday night, then the second surge will take place from northwest to southeast over the region this weekend,” Travis explained.
Unlike some blasts of chilly air that have occurred in recent weeks in the region, this cool push will not race hundreds of miles out to sea over the Atlantic.
