Some forecasters discuss if the Benard cells are interfering with the banded patterns over the lakes. The Tug Hill Plateau and Lake Ontario snowbelts start to receive heavy snowfall. Surface temperatures throughout the lakes are at or below freezing and 850 Mb temperatures continue to reduce to below -10C throughout the entire region. Nov. 11 - p.m. After dark, a clear increase in intensity and coverage of the strong lake bands is observed.
Snows continue heavily for most snowbelts.
Thunder and lightning is reported for a third night in a row in NE Ohio. The storm slowly winds down. Warm air aloft and the development of a capping inversion in the western lakes advects slowly eastward shutting off the heaviest snows. Introduction Terms for using data resources.
