A deepening low pressure responsible for bringing snow to the Northern Tier of the US Tuesday into Wednesday and severe storms from the Ohio Valley through the Gulf Coast on Tuesday will also be the reason for potentially damaging winds this Wednesday for parts of the Northeast.
The minimum central pressure of this storm will drop from the mid-990s on Tuesday when it’s over the Central US down to near 980 millibars by midday Wednesday. This is almost like a “bomb cyclone” or a rapidly-strengthening low but over land as it heads to Canada. On Wednesday, this storm will also bring a strong line of rain and thunderstorms during the morning and midday hours through most of the East Coast. With strong-upper levels winds, these storms alone could produce damaging winds, but the overall circulation of this low pressure system will be responsible for the strong winds.
A tight pressure gradient between the low pressure and high pressure to the south and west will also help produce these winds. So across most of the Northeast, winds are expected to gust up to 30 to 50 mph and in some cases as high as 65 mph. These winds are expected to peak Wednesday morning through the midday hours, but the winds will remain gusty into our Thursday and Friday as well. High Wind Warnings and Wind Advisories are currently in place for much of the Northeast due to the potential for wind damage.
Therefore, scattered power outages can be expected, and because the ground is saturated across much of this region, it will be even easier for the winds to topple the trees.
