Snow Squalls May Impact New Year's Eve Travel from the Great Lakes to the Northeast; Heavy Rain Returns to California

An Alberta clipper will bring lake effect snow downwind of the Great Lakes, with the highest snow totals downwind of Lakes Erie and Ontario. Snow squalls may impact New Year's Eve travel during the evening and overnight hours across parts of the Great Lakes, Ohio Valley, and Northeast. Heavy rain will bring a flash flooding threat for southern California on New Year's Eve into New Year's Day. Read More >

February 24-25th 2011 Winter Storm

Low pressure, tracking from Arkansas the evening of the 24th, to southwestern Pennsylvania the morning of the 25th, brought a large area of snow to the forecast area. The snow was slow to start as dry air remained in place across much of the area, keeping much of the forecasted amounts from being realized. However, once the snow did develop, several bands of moderate to locally heavy snow formed with snowfall rates of an inch or more per hour. The snow quickly ended by mid morning of the 25th. Images before show the Surface Low Maps, select radar images and observations and the 24 hour total for snowfall (Thanks to all that sent in reports).
