The morning models have cleared the internet and it still appears much of the area is in line for several inches of snow Saturday night. The clipper that generates the snow tracks from Nebraska into EC Missouri laying down a swath of snow that covers all but my far southern counties.
The event does not begin until late Saturday evening and due to the swift speed of the clipper most of the accumulations occur in a 6-8 hour window. In other words, the snow is exiting west to east come early Sunday. By then the damage is done with much of my area picking up 2-4 inch accumulations. South of HWY 34 amounts taper off into the 1-2 inch category.
A winter storm watch is out for much of central Iowa extending as far east as Waterloo and Marshalltown. It is likely that a winter weather advisory will be issued for much of my area at some point today, particularly my counties north of HWY 34.

The greatest impacts from the storm are expected to occur in NC Iowa where up to 7 inches of powder is possible.

The official NWS snow forecast looks like this with slightly heavier amounts west of the Mississippi.

Here's what this mornings model guidance is suggesting for snow totals Saturday night. These are not forecasts, just raw model output that forecast are derived from.
The EURO

The GFS

The 3K NAM

The 12K NAM

The 10k Canadian RDPS

The NBMv5 a blend of 30 different models and ensembles.

Some minor alterations in track are still possible but for the most part confidence is high the majority of my area will see 2-4 inch totals and some slick travel conditions later Saturday night and early Sunday. It is possible a few 5 inch reports are possible in a narrow axis, especially in parts of EC Iowa. That's the latest and greatest for now. Roll weather...TS
