Look for some PM clouds with highs generally in the low to mid 40s today. Winds will be a bit breezy this morning & afternoon, with some gusts of 25 to 30 mph expected.

November 2019 Review: Well below normal temps driven by record cold first half of month. Below normal precip, but above normal snowfall due mainly to the November 11th event. https://t.co/xfswyWKs0L #ilwx #inwx pic.twitter.com/ZT4ScGRu8G

Review of meteorological Fall 2019 (Sep-Nov). Temps ended up slightly below normal due to the cool Oct-Nov. It was a top 10 wettest Fall (despite dry Nov) due to extremely wet Sep-Oct. Also top 10 snowiest Fall due to late Oct & Nov. 11 events. https://t.co/xfswyWKs0L #ilwx #inwx pic.twitter.com/iizuVLlWGR
