ST. CLOUD, Minn. (KNSI) - National Meteorologists are warning of a severe weather system that could develop tonight across the upper mid-west, putting the area on alert from a so-called "derecho" system.
Forecasters say they are careful using the so called "D-Word"...but a derecho is possible in a swath from far eastern Montana and Wyoming across to eventually Ohio by early Thursday. Areas south of Central Minnesota down to far Southern Minnesota are the only part of the state listed in the path of the potential storms.
Derecho systems bring wind gusts of 70 miles an hour or more, strong enough to rip shingles off a roof, knock down trees and even tip over semi-trailers. In the off chance, tornados could also be spawned and hail the size of golf balls could fall. Metro areas like Milwaukee, Chicago, Detroit and Cleveland are directly in the cross-hairs of the system.
Forecasters put the chance of the system bringing severe weather at 30%, and urge everyone near the areas to be vigilant in listening to all weather warnings.
Last year, a derecho with 80-mph winds raced across Ohio on June 29, leaving more than 300,000 without electricity in central Ohio amid downed trees and power lines. Some waited up to a week for power to be restored.
Derechos generally occur every one or two years.
