February 5-6, 2010
Winter Storm

A complex low pressure system moved from the Gulf coast to the mid-Atlantic region and eastern seaboard. While the primary area of low pressure impacted the Washington DC area, a secondary area of low pressure and upper level trough brought significant snow accumulations to portions of the Ohio Valley on February 5 and 6. The heaviest snows impacted areas near and north of the Interstate 70 corridor, where totals in the 12-14 inch range were relatively common. Further south, snow mixed with rain at times during the day on Friday, leading to lower final accumulations of snowfall. Locations in the Cincinnati metropolitan area received 4-8 inches of snow, with 2-4 inches of snow along and south of the Ohio River.
