A large upper trough was situated over eastern Canada and across the Ohio Valley January 25-26, 2010. Strong upper air disturbances rotating through the base of the larger trough produced periods of light snow over the region. In addition, strong low pressure in southern Ontario produced a tight pressure gradient across the Midwest. Snowfall was only in the 1 to 3 inch range in eastern Iowa, western Illinois and extreme northeast Missouri. However, northwest winds gusting to 45 to 50 mph caused brief near-blizzard conditions with local whiteouts in rural and open areas. Trained spotters reported visibilities less than 1/4 mile to near zero at times. The worst conditions occurred during the afternoon and evening of January 25, but significant blowing and drifting was still being reported in some areas during the early morning hours of January 26.
