The Missouri Department of Transportation has issued a travel advisory for the weekend because of anticipated snowfalls of up to three inches per hour that could make driving nearly impossible at times.
Rain is expected to turn to snow Saturday afternoon across the state, posing a risk for travelers because of the rate of snowfall and lack of visibility. The storm is expected to continue until about noon Sunday in the western part of Missouri and taper off across the state throughout the day.
The number of passengers traveling through Lambert Airport in St. Louis is on the rise.
Airport officials said Tuesday that Lambert served more than 12.7 million passengers in 2012. That included 6.4 million departing passengers and 6.3 million arriving passengers, both up a little more than 1 percent over 2011.
Lambert officials say 47 percent of passengers last year flew on Southwest Airlines, an increase of 2 percent over 2011. American Airlines was second with 16 percent of passengers, followed by Delta with 13 percent.
