The winter systems have continued at a fast pace this February and unlike January, these systems have packed a lot more moisture. This moisture should help the drought situation building in the state, but with frozen soils, this water tends to mostly run away. The featured analysis only depicts the snowfall reports, but other locations received some freezing rain and rain. Our next storm system arrives already on tomorrow, Saturday.
