Weather Underground Forecast for Tuesday, November 17, 2009.

Wintry weather will persist over the Central US on Tuesday as a strong low pressure system spins over the Midwest. The system that brought snow to the Central Rockies will continue bringing light and scattered snowfall the the region. This interesting storm track is expected to trigger 2 inches of snow in the Central Plains, while the Upper Midwest and Northern Plains will only see a few clouds as higher pressure hovers over the region. This unusual scenario is due counter clockwise flow around this system pulling warmer air over the Mississippi from the South and cool air moving over the Plains from Canada. This will also pull moisture in from the Gulf of Mexico and allow for scattered showers over the Mississippi Valley. Light sprinkles will reach into the Great Lakes, while the Mid-Mississippi River Valley will see 1 inch of rain throughout the day. To the west, cool air pouring in behind this system will allow for light snowfall in Kansas and Nebraska. The North will remain in the 40s, while the Central Plains will see highs in the 30s.

Along the East Coast, the low pressure system will start to push eastward and bring scattered clouds to the region with rainfall reaching to the coast by evening. Highs will remain in the 60s over the Mid-Atlantic States, while the Northeast will see another sunny day with highs near 40.

In the West, another low pressure system off the coast will push into British Colombia and create a cold front that will sweep through the Pacific Northwest. This will bring another dreary and wet day to the region, with rainfall totals up to 1 inch and a dusting of snow in the Cascades. The rest of the West Coast will remain cool as this system pushes moisture over the coast.

Temperatures in the Lower 48 states Monday ranged from a low of -6 degrees at Laramie, Wyo. to a high of 84 degrees at Miami, Fla.
