Weather Advisory – April 27, 2019

A potent storm system is expected to bring a risk for a significant late-season snowfall to parts of the region on Saturday afternoon and evening in an intense but narrow band. Confidence on where this band will set up remains low, but the potential exists for locations within the Winter Storm Watch to experience a heavy wet snowfall with amounts of 4 to 8 inches.

* WHAT…Rain, transitioning to a heavy, wet snow early in the afternoon on Saturday. Total snow accumulations of 4 to 8 inches will be possible by Saturday evening. Winds could gust as high as 35 mph resulting in reduced visibility and hazardous travel.

* WHERE…McHenry, Lake IL, Kane, DuPage and Cook Counties.

* WHEN…From Saturday afternoon through late Saturday night.

* ADDITIONAL DETAILS…Travel could be very difficult in heavy snowfall with greatly reduced visibility. In the heaviest snowfall, rates could approach 1 to 2 inches per hour. A Winter Storm Watch means there is potential for significant snow, sleet or ice accumulations that may impact travel. Continue to monitor the latest forecasts at http://www.weather.gov.
