Lake-effect Snow and Whiteout Conditions in the Great Lakes Region; Below-average Temperatures in the East

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 >

Overview

Severe storms moved through much of the region on the evening of June 16th, 2014, producing torrential rainfall and strong to damaging winds. The line of storms developed in southwest Minnesota and northwest Iowa and drove eastward through the evening.

Some hail occurred too, with golf ball size hail reported near Strawberry Point, Iowa.

The hardest hit area was Platteville, WI where 5 injuries occurred, cars were flipped and some buildings destroyed. The storms also produced some flash flooding in portions of southeast Minnesota where 2-4 inches of rain fell in 2 hours or less.

The storms were the result of a strong flow of warm, moist air from the Gulf, a wavering west to east running frontal boundary, and a very unstable atmosphere.
