Severe Weather and High Winds November 17-18, 2013

November 17-18, 2013

Severe Weather & High Wind Events

Overview

A powerful low pressure system strengthened and tracked northeast from the western Great Lakes towards James Bay during the afternoon of November 17th through the overnight hours.  This intense system brought severe weather to many parts of Illinois, Indiana, Ohio, and Michigan.  Above normal temperatures and strong winds in both the upper and lower levels of the atmosphere help in creating just the right environment for severe storms and tornadoes.  Southerly winds out ahead of the cold front allowed temperatures to soar into the lower to middle 60s during the afternoon hours across southeast Michigan. A line of thunderstorms developed with the cold front that swept through the area during the evening hours. Several of these storms produced severe wind gusts and wind damage as they moved through the area.  Behind the cold front, gradient winds gusted to 50 to 60 mph during the overnight hours, producing additional damage across southeast Michigan.  Below is a map of the severe weather warnings and reports collected during the evening hours, along with a radar loop from 3:00 pm to 8:00 pm EST.  Additional resources are also available from various National Weather Service offices that were affected with this strong storm system.
