An excited and frustrated boy watches hopefully as wintry weather develops slowly into a "big snow." While "helping" his mother with holiday housecleaning, a boy keeps a watchful eye on the progress of a winter storm. He's hoping for a big snow. A really big snow. Inside, he is underfoot, turning sheet-changing and tub-scrubbing into imaginary whiteouts. Outside, flakes are flying. But over the course of a long day (for Mom) the clouds seem slow on delivering a serious snowfall. Then comes a dreamy naptime adventure, marking just the beginning of high hopes coming true in this irresistible seasonal story.
