November Precipitation Highlights:

Liquid-equivalent precipitation was well below normal central Illinois, and slightly below normal for southeast Illinois. Amounts ranged from 1-2" for much of central Illinois, to as much as 4" in southeast Illinois. This resulted in monthly deficits of 1-3" for many areas north of I-70.
Snowfall was well above normal across the entire area. This was primarily the result of snow that fell across the region on the 11th. Snowfall of 2-4" was common over much of the area from this storm. With normal November snowfall around an inch or less, this put many areas a few inches above normal for the month.

November Temperature Highlights:

Very cold conditions dominated the area for the first half of the month. A few days saw record low temperatures, with the coldest air of the month occurring on the 11th-13th, when lows in the single digits and teens were common. Combined with highs in the teens and 20s, this produced daily average temperatures as much as 30 degrees below normal. Temperatures moderated for the last two weeks of November, when several days saw above normal temperatures. Overall, the month ended with readings of 6-7 degrees below normal, which was near the top 10 coldest Novembers for several sites.
