Here we go again. Drag out the heavy winter artillery for another round of, well, let me just put it this way, a complete and utter mess over the next couple of days. I think we'll be spared from the worst in the Twin Cities, but winter storm and blizzard warnings have been posted up north. Up to a foot of snow and close to 60mph winds off of Lake Superior will create quite a mess. This wet, heavy, stuff along with big winds, may be responsible for sporadic power outages in a few locations up north as well. A cold, brisk wind, with scattered snow showers will round out the storm as it swings through Wednesday. Total accumulations around the Twin Cities should be around 1" to 3" with the higher end of that scale being on the northern side of the suburbs.

 At this point, rain is the last thing we need with ongoing spring flood concerns.The threat for moderate and major flooding looks more and more likely for prone locations if this keeps up.
