Overview
|
Fast Facts: A strengthening low pressure system caused strong winds ahead of and behind a powerful cold front on Tuesday, November 10th. In addition, a fast moving line of severe thunderstorms moved across the area from mid-afternoon through the early evening. The line of severe thunderstorms produced numerous observed severe wind gusts, some significant. There were pockets of extensive wind damage, and two EF-0 tornadoes occurred in DeKalb and Kane counties. Furthermore, hail larger than quarter size (1" in diameter) was observed in portions of Winnebago County. The DeKalb and Kane County EF-0 tornadoes are the first November tornadoes to occur in NWS Chicago's County Warning Area (CWA) since 10 tornadoes touched down or crossed into the CWA during the November 17, 2013 tornado outbreak. Dating back to 1950, there have now been a total of 23 tornadoes to occur in the NWS Chicago CWA during the month of November. |
