'Winter' storm barrels toward Midwest, threatens onslaught of snow By Greg Botelho and Holly Yan, CNN March 24, 2013 -- Updated 0540 GMT (1340 HKT) The "winter" storm is heading into the Midwest and could eventually hit Washington Parts of eight states, from Kansas to Virginia, are under winter storm warnings Sunday A burning semi-tanker was among 20-50 vehicles involved in a Colorado wreck (CNN) -- The deluge of snow from the Rockies to the Midwest won't go away anytime soon, no matter what the calendar says. Parts of eight states will be under winter storm warning Sunday, despite the fact it's not winter anymore. The storm threatens to pummel a swath from Missouri to Ohio with 6 to 10 inches of snow, the National Weather Service said. The snowstorm had already rolled over parts of Kansas and Nebraska and was expected to continue barreling east, dumping snow on Louisville, Kentucky, and possibly Washington, D.C., by Monday. In many places, the storm starts as rain before temperatures cool and it changes to snow. Some places might even get sleet. Add winds gusting up to 40 mph and you get one wintry mess. Whiteout in the Rockies Snow pummeled much of Colorado on Saturday, causing a barrage of travel nightmares. Those wanting to fly out of Denver International Airport just had to wait. About 45 miles north of Denver, northbound Interstate 25 was shut down Saturday after 20 to 50 vehicles either crashed or spun off the roadway, the Colorado State Patrol said. Flames engulfed a semi-tanker caught up in the mess. Fortunately for Colorado, the worst of the storm has passed. But with Punxsutawney Phil's botched prediction for spring, it's unclear how many more winter storms lie ahead.
