Winter Storm

A significant winter storm system over the Plains moved into the mid-Mississippi Valley, spreading a wintry mix of precipitation across the Ohio Valley during the evening hours of February 21 into the morning hours of February 22. With sub-freezing temperatures near the surface, the precipitation started off as a mix of sleet/snow early on and then transitioned to mainly freezing rain as warmer air aloft nosed into the region. Snow and sleet accumulations were generally less than an inch, and ice accumulations from freezing rain generally ranged from one to two tenths of an inch.
