The National Weather Service in St. Louis has issued a winter storm watch, in effect from late Wednesday night through Thursday evening.
Precipitation is expected to expand into the Ledgerland area beginning late Wednesday night as snow or sleet, then continue through the day on Thursday with freezing rain joining the mix – especially for areas along and south of Interstate 70.
The wintry mix is expected to taper off Thursday evening as freezing drizzle.
Snow and sleet accumulation potential of up to six inches is possible, along with the potential of up to two-tenths of an inch of ice.
The heaviest snow accumulations are expected to be across northeast Missouri with the largest ice accumulations in central and southeast Missouri.
The storm will be accompanied by southeast winds at 15 to 25 mph with gusts up to 30 mph.
Heavy snow, sleet and ice accumulations will have significant impacts on travel.
Ice may cause damage to trees and power lines.
The NWS weather statement concludes: "A winter storm watch is advance notice that severe winter weather is possible in the watch area. It does not mean it is a certainty. Those in the watch area should begin preparing in case the storm does materialize. If you have travel planned, you may want to adjust your travel time to avoid the storm. Also, you should use this advance notice to make certain your vehicle is winterized.
"Make preparations at home by stocking emergency supplies such as food, medicine and extra heating fuel, just in case the storm makes travel impossible. This is expecially important for those living in rural areas."
