A storm system currently moving out of the Rockies will move northeast through the southern Plains and heart of the Midwest to deliver accumulating snowfall to the central/northern Plains and Upper Midwest. High resolution model forecasts, like the one shown above, depict snowfall reaching beyond the 12 inch mark in Iowa and portions of Nebraska. For anyone who saw yesterday's post concerning that banding in Nebraska, I find it to be no surprise that forecasts have changed yet again and shifted this heavy band. Models never handle these isolated bands of heavy snow well. The purple areas express snowfall forecasts of 6-12 inches of snow, and this looks to be in store for Wisconsin into the heart of Iowa, parts of Kansas and portions of Nebraska. Lighter snow in the 3-6 inch range will fall in the blue regions, and even lighter amounts look to be in store for the light gray colors. Winter weather alerts are posted below.
