Record warmth expected before mid-week cooldown and storms

Summarised from 2 outlets · 6 reports · Updated 12 Oct, 22:43 · Archive

Unseasonably warm temperatures in the 80s are expected early this week, with record highs possible, before a cold front brings storms and a sharp cooldown by week's end.

Unseasonably warm weather with highs in the mid-to-upper 80s is expected for the start of the week. Rockford officially broke the local record on Monday, 12 October, reaching 87 degrees at Chicago Rockford International Airport, surpassing the previous record of 85 degrees set in 2008. Southwesterly winds will remain light to moderate throughout the period.

A series of cold fronts will bring significant changes beginning late Tuesday night. Rain and thunderstorms are expected to move in late Tuesday night and into Wednesday morning, with some showers and storms producing locally heavy rain and gusty winds. The Storm Prediction Center has placed some counties in a marginal risk for isolated strong to severe storms. Additional rain is forecast for Thursday as a strong cold front approaches the region.

Temperatures will drop sharply by Friday, with highs falling into the 50s and 60s. As colder air moves in through the weekend, frost or light freeze conditions are expected Friday night into Saturday morning, potentially the first widespread frost of the season across the region.
