November Witch

http://www.weather.com/forecast/regional/news/november-witch-wind-storm-great-lakes-midwest-nov2015

On par with past storms, known locally as the "witches of November" and virtually on the exact date of the storm that sunk the iron ore freighter Edmund Fitzgerald 40 years ago, a powerful low-pressure system has spread a swath of high winds through the Plains, Upper Midwest, Great Lakes, Ohio Valley and Northeast, that will persist in some areas through Friday.

The low's central pressure bottomed out at 984 millibars (29.06 inches of mercury) near Alpena, Michigan, early Thursday afternoon, the sign of a strong mid-latitude cyclone.

Due to the pressure difference between the cyclone's low pressure and a zone of high pressure over the northern Rockies, strong damaging winds have developed.

Current Wind Alerts

Wind advisories have been issued by the National Weather Service for parts of the Appalachians and portions of western and Upstate New York near Lakes Erie and Ontario.

Wind gusts up to 55 mph are possible in these areas. Such winds developed over a large part of the Plains Wednesday and spread across the Midwest and Great Lakes on Thursday.

In addition, other impacts are possible as this windstorm continues:

• Large waves on the Great Lakes could result in some coastal flooding, including beach and dune erosion on downwind lakeshores.
• Some flight delays are possible due to the winds, particularly at Chicago-O'Hare Airport. This includes some Northeast hubs including Newark-Liberty, where winds won't be as strong, but have been known to trigger flight delays.

Here is when and where the strongest winds will continue.
