...Periods of Moderate to Heavy Snow Through the Afternoon...

Moderate to heavy snow is moving through the area this afternoon,
generally along the Interstate 80 corridor and north. 1-3 inches
of snow may accumulate, with roads becoming slushy to snow
covered, resulting in slick travel conditions this afternoon and
evening. Temperatures and roads are a little above freezing,
resulting in a wet accumulation on roads, but the higher snowfall
rates at times will allow for some accumulation. After 6pm, roads
should start to improve, as snowfall rates decrease. Expect lower
visibilities in the snow as well, where it may be under a mile at
times. Remember, ice and snow, take it slow!
