Remarks for the Time Period
   0      1545 hrs.   T  T  17.8   The snow just started and at a very low temperature! But it only lasted about 5 minutes. This dry air is evaporating the snow before it makes it to the ground.
   1      1745 hrs.   0.1  T  15.6  Larger flakes started at about 1725 and the street is already becoming white and the snow rate is light.
   2      1845 hrs.   0.4  0.01  14.6  The very low temperatures will give a very high snow to water ratio.
   3      1945 hrs.   0.6  0.03  14.0  Light snow rate only 0.2 inches per hour and a very dry fine snow.
   4      2045 hrs.   0.9  0.05  13.8  Snowfall rate 0.3 inches per hour and the ratio of snow to water is now about 20 to 1. Remember the heated tripping bucket gauge that is used evaporates some of the liquid. I will do a core sample at midnight.
   5      2145 hrs.   1.2  0.07  13.6  I believe this is the coldest snow more than 1.0 inch Richmond has had since March 1, 1980. On March 1, 1980 the Richmond International Airport had 10.6 inches of snow and the high temperature was 21 F and the low was13 F giving a daily mean of only 17 F.
   6      2245 hrs.   1.4  0.10  13.3   It was surprising to find snow pellets falling during the last 10 minutes which is causing a little packing. Up until this time most of the flakes have been broken and irregular particles and rarely seen single crystals or dendrites.
   7      2400 hrs.   1.7  0.12  12.8  I took a core sample at midnight and found 0.12 inches of water in 1.7 inches of snow. This gives a snow to water ratio of 14.2 to one and this was after about 30 minutes of snow pellets which are denser than snow we were having earlier. This is much more accurate than using a heated tripping bucket snow gauge.
   Jan 29      0100 hrs.   2.0    12.9  The snow measurments are not taken on the camera snow board and that snow board is not cleared at midnight. The other three snow boards show an additional 0.3 inches of snow.
   9      0200 hrs.   2.5    12.8  It still looks like 2 more hours of snow!
  10    0730 hrs.   3.1  0.17  11.1  The snow ended around 0400 with snow that was filled with dendrites. If you observe snow closely you will find most snows are most often irregular broken crystals of snow. The commonly shown dendrites shown for snow are really not that common. This was one of the coldest snow in the history of Richmond area. The January 30, 2010 snow of 9.5 inches was a cold snow the high was 27 F and the low 18 F a daily mean of 22.5 F. But this snow was colder. The maximum yesterday at the Airport was 27 F and the minimum was 14 F for a daily mean of 21.0 F. I believe this is the coldest snow of more than 1.5 inch Richmond has had since March 1, 1980. Not many would look to the month of March for the coldest snow! On March 1, 1980 the Richmond International Airport had 10.6 inches of snow and the high temperature was 21 F and the low was 13 F giving a daily mean of only 17 F. Taking a core sample this morning on the total depth of snow 3.1 and melted out only 0.17 inches of water. This gives a snow to water ratio of (18 to 1) a very dry snow indeed! The snow pellets that occurred before midnight made the snow to liquid ratio lower (12 to 1). We had about 1hour and 40 minutes of snow pellets from 2240 to 0020.
