Lake enhanced snow showers will be falling along the eastern shores of Lake Ontario today (Wednesday), bringing several inches of accumulation. Winter weather advisories have been issued for up to 6" of snowfall. Totals will be lower around Lake Erie, with only a couple inches expected near Buffalo and Rochester, NY.
An upper level disturbance and a surface trough will bring moisture and energy for snow showers. The warm lake waters will enhance snowfall. Water temperatures are in the 40s to near 50 degrees, but air temperatures are 20 to 30 degrees colder at cloud level, producing additional clouds and snow. Coupled with an offshore, westerly wind over the lakes, the heaviest snow will fall on the eastern shores of Lake Ontario near Watertown, NY.
The trough of low pressure will move across the region through this afternoon (Wednesday), bringing the areas of snow. The system will move east of the Great Lakes tonight and snow showers will come to an end.
