A winter storm watch has been issued for across southern Minnesota, including the Twin Cities metro area, as chances for snowstorm impacting the area Tuesday-Wednesday are increasing. 

Areas within the watch box could see 6+ inches of snow. Details from the National Weather Service: 

"A Winter Storm Watch is in effect Tuesday night and Wednesday morning east of a line from Canby, to St. Cloud, to Cambridge, Minnesota. This includes all of the Twin Cities metro, southern Minnesota, and west central Wisconsin. Snowfall totals of 6 or more inches are possible in the watch area. In addition, gusty northeast winds Tuesday night will shift to the northwest Wednesday, resulting in areas of blowing snow. Travel could be significantly impacted through at least Wednesday morning.

Snow will develop across southern Minnesota late Tuesday afternoon and spread northeastward across central Minnesota and western Wisconsin Tuesday night. The snow may be heavy at times. Snow will end from west to east Wednesday morning, but blowing snow could continue into the afternoon."

The storm track could still shift, so expected snow totals could change and will undoubtedly be refined over the next 48 hours.
