Severe thunderstorms are likely today across the northern Plains and into the upper Mississippi Valley. Gusty winds and dry conditions will result in widespread critical fire weather through Saturday across parts of the Four Corners region and the Great Basin. A significant and dangerous heat wave will expand from the Central U.S. into the Eastern U.S this weekend through much of next week. Read More >
Overview
|
A quick-moving system on Sunday night, March 12 into early Monday, March 13, brought widespread snow, before lake effect snow started Monday night and persisted through Tuesday, March 14. This lake effect snow was oriented into northeast Illinois for a lengthy period, which is rare, as Michigan and northwest Indiana are typically the more favored locations for lake effect snow. The first round of snow caused impacts to the Monday morning commute, while the next lake effect round brought major impacts to the Tuesday morning commute.
