Winter storm delivers: Track snowfall totals

Our Friday winter storm is delivering impressive snowfall totals across parts of southern Minnesota.

Here are some tools to track and post your own snowfall totals as the storm progresses.

Here are auto-updating snowfall reports and a map from the National Weather Service.

Here’s a running list of snowfall totals from IEMBot.

Narrow heavy snowfall band

One of the most interesting features of this snow event is the very narrow and intense heavy snowfall band that set up across the southern Twin Cities. This band cranked out snowfall rates of 2 inches per hour under a very narrow area.

This intense snowfall band is driven by what we call frontogenesis.

Snowfall rates will taper off through midnight and end from west to east between midnight and 6 a.m. across southern Minnesota.
