Late October and Early November are considered a second severe weather period after April, May and June. This is due to the leftover warmth of the summer still lingering across the south clashing with the first real pushes of winter air across the upper midwest. What lies in between both air masses is usually a strong cold front and a deepening low which produces bursts of high wind and often times, a line of severe storms.
Tuesday, October 26th, a deepening low over the western Great Lakes was evolving into a severe weather producing machine. Note the "L" at the top of the map taking up 50% of the country. But this storm is different. The pressure is lower than ANY great lakes storm since 1978 acording to the National Weather Service office in Chicago
Moisture (warmer colors) feeding into the storm aided in the development of severe storms.
HIGH WIND WATCHES and WARNINGS shown with tan watch boxes stretched from Montana to eastern Tennessee.
Early morning tornado watch boxes were issued from Chicago, south to St. Louis and east to Cleveland.
Northern Ohio was under a "high risk" for severe weather for the first time in years. This designation is typically reserved for tornadic weather in tornado alley, not Ohio.
Expect power outages through early Wednesday across northeastern Ohio through early Wednesday.
