Weekend warriors beware.
The National Weather Service on Friday issued a winter storm watch from Saturday evening through late Sunday night.
A wintry mix is expected to begin Saturday night, changing over to all snow by Sunday evening. Accumulations will be 3 to 4 inches of wintry mix, with higher amounts to the north. Winds will be north 10 to 15 mph with gusts up to 20 mph.
Snow, sleet and ice accumulation will create hazardous travel conditions Saturday night through Sunday night across central and east central Missouri as well as southwestern Illinois.
A winter storm watch is advanced notice that severe winter weather is possible in the watch area; it does not mean it is a certainty, according to the weather service. Those in the watch area should begin preparing in case the storm does materialize.
The weather service recommends adjusting travel time to avoid the storm, making sure vehicles are winterized; and stocking emergency supplies such as food, medicine and extra heating fuel.
