A brief warmup this afternoon will give way to snow tonight and Saturday. Highs will be in the 30s, before evening snow pushes in. Minor accumulations are expected in Des Moines, with 1″ possible tonight and another 3″ on Saturday evening.
The snow will continue Saturday night and even through Sunday in far southern Iowa, where storm totals could top 6″ by Sunday night–mainly along the Missouri border. In Des Moines, a weekend total of 4″ can be expected between Friday evening and late Saturday night.
