Weather Underground Forecast for Saturday, January 12, 2013. An intense storm will begin the day over Minnesota before moving northeastward into Canada on Saturday. Before it departs, it will dump heavy snow on the Dakotas and Minnesota in the morning and into the afternoon. In addition to the heavy snow, strong winds will also be likely. These strong winds could blow around the freshly fallen snow and produce blizzard conditions in the Upper Midwest.

Elsewhere, very cold air will remain entrenched over the western half of the country, bringing very cold temperatures to many areas. Higher elevations of the Rockies could dip below -20 degrees for the next several mornings, while the Central Valley of California could see morning temperatures in the teens. Temperatures this cold could put a strain on the agriculture industry in California, potentially damaging sensitive crops. A key number to the damaging point of some crops is how many hours temperatures will remain below 30 degrees.

Meanwhile, a storm will develop along the Gulf Coast before moving quickly into the Mississippi Valley. This storm will carry significant moisture that could provide heavy rain from eastern Texas through Indiana and Ohio. Some of the areas in the Lower Mississippi Valley have already experienced a very wet week, thus extra rain is not particularly welcome at this time.

The Northeast will rise into the 40s and 50s, while the Southeast will see temperatures in the 70s and 70s. The Northern Plains and Rockies will only see temperatures in the 0s and 10s, while the Northwest will rise into the 20s and 30s.

Temperatures in the Lower 48 states Friday have ranged from a morning low of -5 degrees at Kremmling, Colo. to a high of 84 degrees at Plant City, Fla.
