Storm Warning in Massachusetts: High Winds and Snow Expected

A powerful low pressure system will sweep across northern New England into the Gulf of Maine tonight. As it moves toward the Canadian Maritimes, it will rapidly intensify through a process known as bombogenesis.

Wind Conditions and Pressure Systems

A high pressure system advancing from the southwest will generate tight pressure gradients, resulting in strong winds across the region. This pressure difference forces air to flow from areas of high to low pressure, increasing wind speeds.

Air flows from high pressure to low pressure. The bigger the difference, the stronger the winds.

Massachusetts lies between these systems, causing westerly and northwesterly winds to sustain speeds of 20-40 mph, with gusts reaching 50-60 mph.

Timing and Impact of Winds

The strongest winds are expected around 11 p.m. across southern and central New England. Residents should prepare for potential disruptions such as flying debris, power outages, and tree damage.

Temperature Forecast

Temperatures will drop from the upper 50s under cloudy skies to the 40s overnight.

Summary: A rapidly strengthening low pressure system will bring strong winds and potential hazards to Massachusetts tonight through Thursday, with winds easing by Friday.
