UPDATE: 7:08 A.M.

Not much new to add to this story other than the NWS-Twin Cities is calling for a blend of rain and snow Friday into Saturday. The big question will be when and where the rain changes over to snow. 

Original story from Sunday

It's still days out, but the National Weather Service is closely monitoring a large storm system that could pass through Minnesota later this week. 

According to the NWS-Twin Cities forecast discussion from Sunday afternoon, computer models are suggesting a band of heavy precipitation Friday into Saturday, with one model producing a "significant snowstorm" and the other showcasing rain followed by "several inches of snow to accumulate." 

That said, the NWS-Twin Cities advises to not get "too hung up on any one forecast model" this far out in front of the storm. 

Other forecasters are also watching this weather system closely.

Meteorologist Paul Douglas wrote in his blog that the weather pattern is about to get more active and the late-week storm could bring more rain and snow. 

MPR meteorologist Ron Trenda explains that snow amounts all depend on when and where the changeover to all snow happens.
