National Situation Update: Friday, January 2, 2009

Homeland Security Threat Level: YELLOW (ELEVATED).

Significant National Weather

West:
A low pressure system over the northern Rockies will produce rain, snow and gusty winds in the northern half of the region.  The Cascades, Sierras and northern Rockies are forecast to receive up to a foot of snow.  The snow levels will range from 500 feet in the Washington Cascades to 7000 feet in the Sierras.  The winds in southwest Montana and Wyoming will be 35 to 50 mph with higher gusts of 75 mph.  The next storm will hit the Pacific Northwest on Sunday bringing rain, snow and gusty winds to elevations above 1000 feet.
Midwest:
Most of the region will be dry under high pressure.  Tonight, the system moving out of the Northern Rockies will bring snow to the northern Plains and upper Midwest.  Tomorrow the snow will spread from the Dakotas to the western Great Lakes, while rain and a few thunderstorms move northward into the mid-Mississippi and lower Ohio Valley.
South:
A weak cold front will produce scattered rain showers across the region.  There is a possibility of light icing across parts of North Carolina and sleet in the southern Appalachians as temperatures near freezing.
Northeast:
A weak low pressure system will produce a dusting of snow across much of the Northeast and middle Atlantic regions.  In northern New England, up to 4 inches of snow will fall in the higher elevations. Downwind, east of Lake Erie and Ontario, 6 to 12 inches of lake-effect snow is forecast.  Tomorrow, snow showers are forecast from Upstate New York to Maine with gusty northwest winds for New England.
