In the case of snowfall, the total precipitation is given in centimetres. If the precipitation falls as water or sleet, the total precipitation is given in millimetres. Winchester Weather Radar Maps - Motion Local Composite Radar Loop For Current Radar, See: NWS NOTE: We diligently are working to improve the view of local radar loops for Winchester - in the meantime, we can only show the US as a whole. The total precipitation is given in inches. For example in temperatures just above freezing, snowfall with the water content of 10 millimetres of water forms a snow layer 10 centimetres thick on the ground, but in temperatures around -20 degrees Celsius the layer formed by same amount of water is 20 centimetres thick. If the water content of the rain is kept constant, the colder the weather, the thicker a layer the falling snow forms on the ground.įor example in temperatures just above freezing, snowfall with the content of a quarter of an inch of water forms a 2,5 inches thick layer of snow on the ground, but in temperatures around -5 degrees Fahrenheit the same amount of water forms a layer of snow 5 inches thick. Temperatures also affect how much a given amount of snowfall grows the amount of snow on the ground. These factors cause the amount of snow on the ground to grow less than the snowfall amount. The total snowfall refers to the snowfall from the cloud and does not take into account local melting, packing or drifting of snow. The total precipitation forecast gives the expected total precipitation for the whole 24-hour day.
