Low pressure will strengthen over New England Saturday morning and lift rapidly northward into Canada Saturday afternoon and night. On the backside of this storm center, a period of strong – perhaps damaging – west winds are likely over the area during the second half of Saturday.
Saturday is likely to start gray and wet, with downpours, gusty winds and maybe even a thunderstorm or two crossing the area. However, during midday and early afternoon a cold front will sweep eastward over the Cape and push that activity offshore.
Not long after that frontal passage winds will abruptly increase from the west and really howl through the afternoon and into the evening hours.
The combination of a sharp pressure rise associated with the rapidly departing (and strengthening) low pressure center, incoming cold air and a well-aligned wind flow in the atmosphere will result in
sustained winds of 20 to 35 mph over the area with frequent gusts over 40 mph…and a few gusts of 50 to 60 mph likely.
Some tree and limb damage is possible and that could bring some localized power disruptions.
