Dangerous snow storm conditions are expected Tuesday evening into Wednesday morning.

On Monday, the National Weather Service issued a Winter Storm Warning for much of Southern Minnesota and parts of Northern Iowa. This warning signifies that dangerous winter storm conditions are soon expected to occur. In this case, we are anticipating a strong winter storm moving through Tuesday evening through Wednesday morning. 

Large swaths of 5-10 inches of snow are expected to fall overnight Tuesday, while winds will be gusting above 40mph late Tuesday through Wednesday. This will make for dangerous driving and outdoors conditions as visibility will be severely reduced and roads will quickly become slippery. At the top end of what is possible, conditions on Tuesday night even have the potential to be classified as a blizzard. 

There is good certainty that the snow will begin Tuesday afternoon (5-10pm), and end by around noon (9am-2pm) Wednesday. There is also good certainty that this storm has the capability to drop a lot of snow in a short amount of time given the large amount of moisture that will be present in the atmosphere. 

One area of contention in the forecasts is the placement of the rain/snow line. Some areas on Tuesday night and Wednesday morning will be warm enough for precipitation to be rain, but the line between rain vs. snow is very thin. As of Monday afternoon, there is good confidence that most of Northeastern Iowa and a sliver of the southeasternmost part of Minnesota will see some rain. Keep in mind though, that any small deviation in where this rain/snow line sits could mean the difference between seeing half an inch of snow, and 6+ inches of snow. The margin is that thin. Some computer models show Mason City Iowa receiving 1 inch of snow, and others show 10 inches.

NWS LaCrosse (Southwestern Wisconsin, Southeastern Minnesota, and Northeast Iowa)
...Hazardous Travel Expected Tuesday Night into Wednesday... .A winter storm will result in hazardous driving conditions Tuesday night into Wednesday with significant snowfall for much of the area. A band of 5 to locally 10 inches of accumulation is expected across portions of north-central Iowa, southeast Minnesota, and west-central into north-central Wisconsin. In addition, gusty winds will result in some blowing snow and poor visibility. As precipitation tapers off Wednesday morning, some areas could see a brief period of light freezing drizzle which may result in a light glaze of ice. There will be a sharp cutoff to the southern edge of the accumulating snow, and where this transition zone sets up will determine which areas see more snow versus rain. A slight shift in storm track or a slight variation in temperature will have big impacts on storm total snowfall. If you plan to travel Tuesday night or Wednesday, allow plenty of extra time to reach your destination, pack an emergency kit, and monitor the latest forecast. ...WINTER STORM WARNING IN EFFECT FROM 6 PM TUESDAY TO 6 PM CST WEDNESDAY...
