An intense band of snow is expected to set up across portions of Minnesota on Monday into Tuesday and more than foot is possible for some areas.
Currently, a Winter Storm Watch is in effect for parts of central and eastern Minnesota into west-central Wisconsin. Brainerd, Grand Rapids, Hinckley and Duluth are all in the watch area.
It does not include the Twin Cities but that could change, according to the National Weather Service, which says it is highly confident the storm will bring almost all snow to areas within the watch, whereas the metro area is currently forecast for more rain than snow. But that could quickly change, it warns.
"Though the Twin Cities is currently not in the watch and has more rain than snow in the forecast for Monday, there is guidance that shows mostly snow for the Twin Cities as well, and if that were to end up being the case, we could see significantly higher amounts than what is currently forecast for the Twin Cities, so this certainly bears watching closely for the Twin Cities metro area as well."
That same forecast discussion says computer models are suggesting 1.2 inches of water in the storm. Just one inch of water is equal to a foot of snow, so this thing has some significant snow potential with it.
Areas hit by the heaviest snow can expect 1-2 inches per hour, and it's expected to be ongoing during rush hour on Monday evening, meaning travel could be severely impacted.
The Grand Forks, North Dakota branch of the NWS is already suggesting that anywhere in Minnesota north of I-94 has a moderate risk of seeing 6+ inches of snow.
Less than 24 hours ago the NWS forecast wasn't nearly as aggressive in snowfall predictions with this storm – and they're still not entirely comfortable predicting exact snowfall amounts – so it bears paying close attention over the next 48 hours.
