Snow Slams the Great Lakes

As harsh, cold winds continue over the relatively warm Great Lakes waters, more snow will blast downwind areas through the middle of the week.

Some locations downwind of the Great Lakes have been buried by feet of snow since a lake-effect snow event began this past weekend.

Several inches to a foot of new snow will blanket areas downwind of the Great Lakes as well as along the spine of the central Appalachians through tonight.

The heaviest snow will target portions of the southern shores of lakes Erie and Ontario, where snowfall for the 24-hour period ending late tonight could even top 1 foot in a few spots. However, the snow will not stop late tonight.

The region will continue to be pounded by heavy bands of snow and snow squalls through Wednesday, with several additional inches of snow piling up in some cities and towns.

"Ruh Roh Raggy!" People are up to their elbows in snow around London, Ontario this week. This photos is from one of our readers on the Canadian Weather Forum.

Travelers along stretches of interstates 79, 80, 81, 86, 90, 94 and 196 could encounter dangerous driving conditions into the middle of the week. Roads will be snow covered and slippery, and travel could become nearly impossible under the bands of heavy snow.

Bitterly cold, biting winds will also cause blowing and drifting snow. On top of creating an uphill battle for beleaguered road crews, near white-out conditions at times can bring ground travel to a standstill.

Those venturing out in the lake-effect snow prone areas should be sure to bring along extra layers and blankets in case you become stranded in a band of heavy snowfall. AccuWeather.com RealFeel® temperatures will dip to the single digits and near zero at times.

The windblown snow could also trigger hefty flight delays in airports across the region, including in Syracuse, Rochester and Buffalo, N.Y., Pittsburgh, Pa., Cleveland, Ohio andFort Wayne, Ind.

People need to pay close attention to the UV index during this time of year. On a sunny day late in the spring and into the summer, the UV is usually at least an 8, which is very high. Readings over 11 are considered extreme values in which only 10 minutes of full exposure to the sun will produce a sunburn.
