November Weather Summary

November 2011 was a month that saw temperatures average several degrees above normal, along with much above normal precipitation.  The warm air prevented much in the way of accumulating snow from falling across central and southeast Illinois for the month.  Several weather systems tracked into the area from the southwest, bringing moderate to locally heavy rains.  The maps below from the Midwestern Regional Climate Center highlight the well above normal temperatures and rainfall for much of the Midwest.

Specific heavy rain events fell on November 20-22, and 26-27.  Totals from these events are shown in the maps below. 

Nov. 20-22


Nov. 26-27

One severe weather event affected the area on the 14th.  Relatively warm and humid air prevailed across the state, but a strong cold front moving in from the northwest triggered a line of severe thunderstorms in eastern Illinois during the afternoon hours.  Wind gusts were recorded as high as 76 mph in Champaign county, downing trees and powerlines and causing minor strutural damage to a few buildings.  Damaging wind gusts and hail as large as quarters continued as the storms tracked into Indiana by the late afternoon hours.

The map below from the Storm Prediction Center shows severe weather reports from the 14th.

The main benefit of the active weather this month was the end of drought conditions across the area.  This was a short term drought which developed quickly during mid-late summer, and ended quickly during mid-late fall.  The latest Drought Monitor shows drought conditions confined to areas west of the Mississippi River as of November 29. 




Here are links to specific climate summaries for area cities.  The summaries for Peoria, Springfield, and Lincoln are the official data for those locations.  For the remaining locations, they are supplemental, meaning another site in the area is the official climate station.
