WASHINGTON (REUTERS) - A storm was forecast to hit the north central United States, dumping 10 to 20 cm of snow from North Dakota to northern Iowa and Illinois on Monday, the National Weather Service said.

Locally heavier amounts of up to 30.5 cm of snow are possible and some areas could see freezing rain, leading to hazardous travel conditions, forecasters said.

The storm was forecast to move east, reaching the Ohio Valley, the mid-Atlantic states and the Washington, D.C., area by Tuesday evening.

"One of the more challenging aspects of this storm will be the snowfall potential over areas along (and) east of Interstate-95 in Virginia and Maryland," the forecasters said.
