A Look Ahead
The potential for significant winter weather remains over the Great Lakes on Saturday as a strong, quick moving upper-level trough moves through the region. There is some uncertainty in whether cold air will be in place. However, the current forecast is for precipitation to begin early Saturday morning as an area of low pressure develops. Snow and sleet accumulations of 2-4 inches are expected in most places. Across the northern Great Lakes, snowfall totals may exceed 6 inches. By late afternoon, precipitation should transition to rain. Elsewhere, heavy snow may develop over the higher terrain of the Pacific Northwest on Sunday as an area of low pressure moves into the region.
