Twin Cities brace for thunder, snow, and potential severe storm system.

A winter storm watch has been issued for central Minnesota, including the Twin Cities area, from Friday evening through Saturday morning. The storm system will bring a mix of rain, ice, snow, and thunderstorms in two waves of precipitation. Heavy snowfall, blowing and drifting snow, and slippery road conditions are expected, with snow accumulations of 4 to 6 inches possible. There is still uncertainty regarding the storm's precise coverage, type, and timing, but the heaviest snowfall is likely to be north of the Twin Cities. Warmer air on the southern end of the storm system also presents a severe risk for southern Minnesota on Friday.
