Snowstorms are storms where large amounts of snow fall. Snow is less dense than liquid water, by a factor of approximately 10 at temperatures slightly below freezing, and even more at much colder temperatures.[citation needed] Therefore, an amount of water that would produce 0.8 in. (2 cm.) of rain could produce at least 8 in (20 cm) of snow. Blizzard warnings went up across wide sections of the U.S. Southwest and Great Plains on Monday, threatening holiday travel ahead of the Christmas weekend.
Warnings forecasting snowfalls of up to 18 inches (.4 meters) stretched across the region as the storm barreled toward parts of New Mexico, Texas, Oklahoma, Kansas and Colorado.
The storm was expected to disrupt holiday travel on major interstates in the region, including Interstate 35 in Oklahoma, Kansas and Texas, interstates 25 and 40 in New Mexico and Interstate 70 across central Kansas.By Thursday, this system should move off the coast with another system forecast to move in behind it.
This second system should begin to take shape in the Southern Plains late Wednesday night, with rain and thunderstorms extending from eastern Texas into the Ohio and Tennessee Valleys: some locally heavy rainfall is possible in this area on Thursday.
