An even more powerful weather system winds up along the Texas coast Sunday, then makes a beeline almost due north for Minnesota. Heavy snow should arrive in southern Minnesota again by Monday morning, and push into the Twin Cities Monday afternoon.

Gulf Storm

We call these "Gulf storms" because they dive down to almost the Gulf of Mexico and suck up high amounts of Gulf moisture. These extremely wet storms can produce some of the heaviest wettest snowfalls of the winter in Minnesota. The infamous Halloween Mega-Storm was a Gulf storm. Nobody is forecasting that kind of snowfall with this system, but the tracks are similar.

The forecast models are very aggressive with snowfall totals early on. This seems reasonable given the likelihood of all snow, with copious amounts of moisture. Right now Monday PM and Tuesday AM rush hours will likely have the highest impacts.

It's still too early to be specific about snowfall totals for any one spot, but the possibility of 6" to 12" totals with this storm across parts of Minnesota are very plausible at this point.
