Two down, one more on the way. It has been a busy week for snow and the most significant system of the three is on the way.

A Winter Storm Watch is in effect from Saturday morning through Saturday evening and includes Sioux Falls, extreme southeastern South Dakota, much of Minnesota, northwestern Iowa and eastern Nebraska. Snow will develop across central Nebraska late tonight and move northeastward into South Dakota, Iowa and Minnesota on Saturday morning. Snow will be heavy at times with accumulation of 5 to 7 inches possible in Sioux Falls. Parts of Iowa and Minnesota south and east of Sioux Falls could get 6 to 10 inches. This system will have a lesser impact north and west of Sioux Falls. Accumulation of 3 to 5 inches is possible in Huron, Mitchell and Watertown, 2 to 4 inches in Chamberlain, 1 to 3 inches in Aberdeen and about an inch in Pierre.

Wind will be fairly light through most of the day Saturday however, gusts could increase to between 20 and 30 mph on Saturday night in places south and east of Sioux Falls.

Stay tuned for updates. As the system develops we will be able to fine tune the forecast track of the storm and make any necessary adjustments to the snow forecast.
