Colorado low early next week?

The models are doing their thing right now, showing a pretty potent Colorado low aiming for somewhere in the northern plains on Monday/Tuesday. Often what happens is the models start out painting the low ending up over Wisconsin, and then move it farther and farther westward until getting it right, usually about 36 to 48 hours out. And often this means that a Colorado low that was originally pegged for Minnesota instead smokes southern Manitoba.

As of this writing the most interesting timeframe for this system is 84 hours--Tuesday afternoon/evening. There is still significant disagreement on the placement, with the GEM-Global placing the low at Duluth and burying Sprague, the GFS placing the centre east of Minneapolis and thus burying Duluth, and the NAM placing the low northwest of Duluth, burying Sprague and Steinbach.

This one has my spidey-sense tingling. Not good for flood potential.
