A powerful windstorm is set to return tonight and continue into Thursday morning. A low-pressure system is moving across northern New England into the Gulf of Maine this evening. As it shifts towards the Canadian Maritimes tonight, the low will rapidly intensify through a process called bombogenesis.
Meanwhile, a high-pressure system is approaching from the southwest, creating a tight pressure gradient. This difference in pressure drives strong winds across the Northeast. Air flows from high to low pressure, and the greater the difference, the stronger the wind force.
The strongest winds will occur around 11 p.m. in southern and central New England, potentially causing trash cans to blow over, power outages, and tree damage.
Temperatures will drop from the upper 50s under cloudy skies to the 40s overnight.
“The wind dies down for Friday afternoon at least.”
Summary: A rapidly strengthening low-pressure system will bring dangerous high winds to the Northeast tonight and Thursday, with gusts up to 60 mph and a significant risk of damage before calming down on Friday.
