Mother Nature must be putting the pieces together because the National Weather Service has gone from thinking 1-2 inches of snow could fall in the Twin Cities on Tuesday to now issuing a winter storm watch. 

The watch was issued at 2:46 p.m. Monday and is in effect from Tuesday morning through Tuesday night. The weather service says the storm track could still change, but as of now the Twin Cities is near where the heaviest snow could fall.

"At this time, a narrow stripe of heavy snowfall is possible from southwest Minnesota to northwest Wisconsin, including east central Minnesota and the Twin Cities metro where 4 to 7 inches are possible," the winter storm watch says. 

"Sleet and freezing rain may mix with the snow from south central Minnesota to north central Wisconsin. The afternoon rush may be significantly impacted with the heaviest snow most likely occurring during that time."

Novak Weather pretty much called this earlier Monday when he said this storm has the chance to over-perform. 

"This is a high risk, high reward scenario with a bust likely for some," Novak Weather said. "On the other hand, this snow system could easily over-perform for others. It will be a narrow, impressive band of snow with snow rates of 1.0"+/hr. at times, especially between 3-9 p.m. Tuesday"

Here's a look at what the radar could look like as the storm system pushes through. You can see the green colors representing rain on Monday evening followed by the low-pressure system spinning through with snow on Tuesday.
