Winter Snow for t. Louis

About how much snow, ice etc are you predicting for St. Louis this season?
Thanks.

St Louis winter

We do not predict amounts but deviations from the norm/average. So, we are predicting above-normal temps, above-normal precipitation, and near- to below-normal in the St. Louis area. We are predicting above-normal snow west and northwest of St Louis, so if the wind picks up … keep the shovel handy.
