See how much snow we could get this weekend

The image above shows the probability of snowfall accumulation depth at the Quad City International Aiaport. The large zero means we have the largest chance we’ll get zero inches of snow. The number 1 is also big which means we’ll have about an equal chance of seeing an inch of snow. Notice how the numbers really get small after that. That means the chance of us getting 2, 3, 4, 5, or 6 inches of snow really gets small.

This alleviates the communication issue we have sometimes by putting out forecast ranges. Sometimes we’ll say “3-6 inches possible” where people lock onto that six inch number. When 2.8 inches fall, people see it as an error. This way, we have the opportunity to keep you updated with the real potential of accumulation. And since snowfall accumulation is the most difficult things to forecast. I’ll keep updating this map on Good Morning Quad Cities, weekdays from 4:30 to 7am.
