Storm Alert | Winter storm watches posted ahead of Friday's wintry mix

We are tracking snow, sleet, freezing rain and rain across the area for Friday

ST. LOUIS — Winter storm watches have been issued for portions of Missouri and Illinois as a winter storm takes shape heading into the weekend. Late Wednesday, a powerful storm system is pounding the Pacific northwest. This system will inspire winter weather to develop across much of the middle part of the country by Friday morning.

Significant winter weather is more likely across parts of central and northern Missouri and west-central and northwest Illinois by Friday where winter storm watches have been posted.

Cold dry air is working into the region and will set the stage for snow to develop when the precipitation first starts Friday morning. For the 5 On Your Side area, the first snowflakes may fall before daybreak along I-44 toward the Rolla area.

After an hour or two of light snow with accumulation of less than an inch, some sleet will mix in and then a change to sleet and freezing rain. The sleet doesn't last too long before it is mostly freezing rain. This icy mix may last two to four hours and create a light glaze of ice, especially on elevated surfaces.
