...Major Winter Storm into Tonight... .A major winter storm will continue to impact much of central and southern Iowa into tonight, with some snow possibly lingering through midday Tuesday. Very heavy snowfall rates of 1 to 2 inches per hour will occur into this evening, leading to heavy accumulations over a short period of time. Increasing northeast winds gusting over 30 mph will cause blowing and drifting snow. Some uncertainty of snowfall amounts remains on the north edge of the snow band, where much less snow totals are possible over a short distance.

* WHAT...Heavy snow expected. Total snow accumulations of 7 to 12 inches. Winds gusting as high as 35 mph.

* WHERE...Central Iowa.

* WHEN...Until noon CST Tuesday.

* IMPACTS...Plan on snow covered roads and low visibilities. Travel may become near impossible at times. Areas of blowing snow could significantly reduce visibility and cause blowing and drifting of snow. Near blizzard and whiteout conditions are possible with travel not recommended in many locations.

* ADDITIONAL DETAILS...This may be a historic event with snow amounts of this magnitude only occurring once every 15 to 20 years. For example, in Des Moines there have only been nine 12 inch daily snowfalls since 1884.
