Depending on where you live, meteorologists are asking people to leave work early to avoid the heavy snowfall.
Stephen Rodriguez, a meteorologist with the National Weather Service, said a blizzard warning is officially in effect from 3 p.m. today until 3 p.m. Wednesday.
However, he said, depending on where people live, the start of the heaviest snowfall is expected to begin in early afternoon, at about 3 p.m.
Worse, he said potential white out conditions will occur as winds gust up to 50 mph this evening.
Rodriguez said the heaviest snow will come in two different waves. The snow will begin to fall heavily near 1 p.m. along the I-80 corridor, then will spread across to the Wisconsin state line an hour or so later.
He said the heaviest accumulation -- with the potential to drop 2- to 3-inches of snow an hour -- will hit around 5 p.m. Tuesday evening, then grow heavier as the evening goes on.
Officials said road conditions will start to become treacherous by late afternoon and dangerous by the evening hours.
They said unnecessary travel should be avoided at all costs by this afternoon.
Though, officials could not pinpoint an exact time the worst will come, they are telling people its better to be safe than sorry. Plan to leave work or school early to avoid the snow rather than staying later only to put their lives at risk.
