Weather Underground Forecast for Saturday, February 11, 2012.

Precipitation will spread across the East Coast on Saturday, while more rain and mountain snow showers are anticipated for parts of the West. A trough of low pressure and associated cold front continue moving eastward across the Eastern Valleys into the Eastern Seaboard. Cool temperatures to the north will allow for snow showers to develop across the Northeast and New England, while rain showers are likely over the Mid-Atlantic states. Rain showers over the Southeastern states should wind down in the early morning hours as the tail end of the system pushes offshore early in the day. Expect the New York metropolitan area to see 1 to 3 inches of snow, while the Washington D.C. area will see a messy combination of snow and freezing rain as high temperatures reach into the lower 40s.

Behind this system, a ridge of high pressure continues to build in from the Plains, pushing cold and dry air in from Canada. This allows for plenty of sunshine to spread from the Plains over the Mississippi River Valley and into the Eastern Valleys. Expect the Northern Plains and Upper Midwest to see highs in the teens again, while the Midwest will see highs in the 20s. Strong winds will accompany this system, pushing windchill values below zero in these areas. The Southern Plains will remain in the 40s on Saturday.

Out West, a trough of low pressure pushes a cold front over the Pacific Northwest and continues pulling moisture onshore with it. This will kick up more rain showers with high elevation snow showers likely in the Cascades. The tail end of the frontal boundary will sweep through California, bringing light rain showers to the coasts and interior valleys. Expect light snow showers in the Sierra Nevadas by Saturday evening.

... Line of heavy snow showers will move through the western shore
counties of the Maryland Chesapeake Bay this afternoon...

At 318 PM EST... Doppler radar indicated heavy snow showers and snow
squalls along a line extending from Millers to King George... moving
east at 30 mph.

The snow band will move through much of the Baltimore metropolitan
areas from 330 PM until 415 PM. This band will extend southward
across the eastern Washington suburbs and into lower southern
Maryland.

Visibilities will be reduced to less than one half mile in heavy
snow. This activity will last only a few minutes in any one
location... and upward of 15-20 minutes at the most. A quick dusting
to coating of snow is possible with this activity... though most Road
surfaces are still well above freezing. Localized areas will receive
around half an inch of snow accumulation.

In addition... wind gusts in the line of precipitation will reach
between 30 and 40 mph at times. Temperatures will drop several
degrees behind the boundary... with wind chills dropping from the low
40s into the 20s.
