Minneapolis-St. Paul snow timeline and essential information

- A Winter Storm Warning is in effect for the central and southern Twin Cities metro from 9 a.m. Tuesday through 6 a.m. Wednesday, while a Winter Weather Advisory covers the north metro.

It will be quiet for the Twin Cities on Tuesday morning as snow is pushes north out of Iowa and into the Interstate 90 corridor for the morning commute, but won’t make it to the metro until around lunchtime. The snow's intensity will increase very quickly after onset and near-whiteout conditions with blowing and drifting snow can be expected for much of the afternoon and evening. Tuesday evening’s commute will be very slow. The snow will hang around through the evening and begin to taper off around midnight, but wind gusts of 30 miles per hour overnight will still cause significant blowing and drifting through tomorrow morning, including the commute.

Snow timelines

1 p.m. to 4 p.m. - Intense wind and snow, 3 to 5 inches of accumulation.

4 p.m. to 8 p.m. - Commute buster! Additional 2 to 3 inches of snow.

8 p.m. to midnight - Blowing and drifting snow, with an additional 1 to 2 inches.

Wednesday morning - Moderate Impact. The falling snow will be done, but blowing and drifting snow is still likely as MnDOT works to clean up the roads. A slow commute is still very likely, but just not as bad as Tuesday evening.

Estimated snow totals

There will be a very sharp NW to SE cutoff to overall snow totals, but much of the Twin Cities metro is expected to be in the 4 to 8 inch category. The southeast has the potential to get more and the northwest metro has the potential to get less.
