Overview

• An Arctic air mass clashing with a substantial amount of Gulf and Pacific moisture led to the development of a massive winter storm that crippled a large swath of the central and eastern U.S. between January 24th and January 26th.

• Locally, the winter storm delivered a broad 2 to 6" of snowfall to locations near and south of I-80 and east of the Fox River from the evening of the 24th through the evening of the 25th. However, lake effect and lake enhanced snowfall produced localized accumulations up to about 10" in Cook County within a few miles of Lake Michigan and up to 6-9" in parts of Lake and Porter counties in northwest Indiana.

• Elsewhere across the country, significant snow, sleet, and ice accumulations were observed from the southern Plains through the Deep South and Ohio River Valley into the Mid-Atlantic and New England.

• Another period of bitterly cold wind chills followed into the morning of January 26th, with minimum wind chills between -15°F and -25°F observed across northern Illinois and northwest Indiana.
