SPC Convective Outlook for Friday, December 8, 2017SPC Convective Outlook for Friday

A Look Ahead
Heading into the weekend, a weak area of low pressure may bring some light snow to portions of the Great Lakes on Saturday. Snowfall amounts of 1-2 inches are expected.  As this area of low pressure moves eastward on Sunday, snow may develop across the Northeast; accumulations currently appear to be light. Early next week, another area of low pressure will bring light snow to the Great Lakes and the Northeast. Snowfall amounts of 1-2 inches are currently expected. As an area of low pressure begins to stall out across the Northeast and strengthen Tuesday into Wednesday, some significant snowfall totals will be possible for the Northeastern US. Models are indicating the potential for snowfall amounts in excess of 6 inches of snowfall during the duration of the event. The heaviest totals will be along the US/Canada border, as well as for the areas of New York bordering the Great Lakes where lake effect snow is forecast.
