Heavy lake-effect and lake-enhanced snow will persist downwind of the Great Lakes and produce some whiteout conditions that could cause difficult travel conditions. A coastal low will produce moderate to heavy snow over parts of southern and eastern New England into the afternoon. Below average temperatures are expected across the eastern U.S., particularly with chilly morning temperatures. Read More >
Event Summary: April 22, 2019
|
An area of low pressure and a cold front tracked across eastern Iowa and northwest Illinois during the afternoon and evening. This front served as the focus for the development of showers and thunderstorms, a few of which became severe. Thunderstorms produced large hail to the size of quarters and wind gusts over 60 MPH. The most notable wind report came from Walcott, IA, where a wind surge in the line of thunderstorms produced an estimated gust of 65 MPH. Hail to the size of quarters was observed in Muscatine, IA and Bettendorf, IA. Additionally, torrential rainfall from thunderstorms lead to rainfall amounts over one inch in the Quad Cities, which produced brief flash flooding along River Drive in Moline, IL.
