# El Niño Impacts and Outlook | Purdue University Pest&Crop newsletter

> Purdue's Pest&Crop newsletter outlines typical El Niño winter patterns for the Great Lakes, with the polar jet stream farther north and warmer temperatures likely. The October outlook favors below-normal precipitation for the central and western parts of the basin, which could reduce snowpack and spring runoff.
