A weakening cold front will eventually become stationary just north and west of the Canadian border today. This boundary extends back south and west, into the southern Plains. Some flurries or light snow showers are possible across the region today, though not much in the way of precipitation is expected.
Low pressure is forecast to form along the stalled out frontal boundary, over the south central United States, tonight. This will cause the northern extent of the boundary to take on warm frontal characteristics. As the ripple of the low pressure rides northward, into the Great Lakes region through the day Saturday, milder temperatures will migrate northward into the Capital Region.
A mix of rain and snow will also overspread the region by Saturday night and into Sunday, as the southerly winds override the warm frontal boundary, inducing precipitation. Generally light precipitation is expected, with better chances for accumulating snows north and west of the Capital Region, closer to the Canadian border and Lake Ontario. Precipitation comes to an end overnight on Sunday, as high pressure builds into the region to start the work week.
Temperatures look to average near to perhaps slightly above normal through the forecast period. Precipitation amounts are forecast to average near normal.
