TL;DR: In this article, the relationship between snow cover and observed maximum and minimum temperature is reviewed, and it is shown that there was a warm bias in the MOS temperature forecasts for the northern Great Plains following the receipt of a fresh cover of snowfall.
Abstract: Research into the relationship between snow cover and observed maximum and minimum temperature is reviewed. An example of the importance of snow cover and forecasting max/min temperatures is presented for this past winter (1976–77). It is shown that there was a warm bias in the MOS temperature forecasts for the northern Great Plains following the receipt of a fresh cover of snowfall. It is proposed that snow cover be incorporated as a conditional predictor to be used only during specific synoptic conditions.

A pair of substantially rigid guides is mounted, one on each side wall of the box near the top edge thereof, and the cover is mounted between the guides with a plurality of hooks or other suitable means secured along each side of the flexible cover material so as to be slidable on the guide means. Fasteners, such as rubber shock cords, are provided to secure the second end of the cover remote from the first end at the second end of the open box remote from the first end when the cover is extended along the length of the box. Indicator means such as flags are provided at the second corners of the cover to indicate whether the cover is extended along the box or not. The guide means are preferably a pair of taut cables. A cover is provided at the first end of the box--usually the front end--and means are provided for securing the flexible cover beneath it when it is to be stowed, such as when the box is empty. When the cover is at the front end of the box, it may be formed with an upwardly directed scoop or air deflector, which tends to cause better air flow characteristics over the box when it is being hauled on a highway at highway speeds.
