|2||Dec.||13th||1.7||Storm 1|| Yes ||Rain started again around midnight and turned to sleet then to snow around 0415. The snow was never heavy but ranged from very light to a few periods of moderate snow. The snow ended as flurries around 1000.|
|3||Dec.||16||1.9||Storm 2|| Yes ||The snow started at 0916 and from 1000 to 1400 it snowed steadily from 0.3 to 0.4 inches per hour. After 1400 the snow became much lighter and a little sleet mixed in with the snow and then the precipitation ended between 1700 and 1800.|
|3.3||Storm 3|| Yes ||The snow started about 1630 and snowed steadily from 1800 to 2300 at a rate of 0.3 to 0.4 inches per hour and then tapered off to flurries by midnight. At midnight the snowboard had 2.2 inches of snow and was cleared. From midnight to 0700 of the 26th we added only 0.2 inches and by noon we had the maximum amount of 1.1 inches for a total of 3.3 inches. But the maximum on the ground was never more than 2.7 inches because of settling. Flurries continued to 1930 but didn't add to the total as they were so light. Snow was much heavier to the east. Portmouth, VA had 11.0 inches and one place in NJ reported as much as 32.0 inches.|
|5||Jan.||7th||0.5||Event 2|| Yes || This was expected to be only snow flurries but some local areas reported as much as 2.0 inches.
It wasn't cold enough to stick to the street and ended a little before midnight but was enough to make the ground good and white. |
|6||Jan.||8th||0.3||Event 3|| NO ||Snowflakes fell as aggregates or fluffy assemblages of many crystals leaving an uneven snow surface and more air spaces in the snow and giving a very high snow to water ratio.|
|7||Jan.||11||0.1||Event 4|| Yes ||A very minor event but included snow, sleet and a little freezing rain in that order. The 0.1 measurement was taken about 0745 just after the heaviest period of snow that turned into sleet by 0850.|
| Event 5
|No||The glaze was less than 0.1 inches of ice but was enough to close Hanover county schools to our north.|
|0.5||Event 6|| Yes ||Rain started at 2300 hrs. on the 25th and contiued on the 26th to 1645 before the snow started mixing with rain and became all snow between 1705-1710. Lightning was seen at 1332 hours during the heaviest rainfall. The maximum snow was only 0.5 inches at 1945. The total rainfall measured before snow started was 1.15 inches. Liquid precipitation from snow was 0.15 inches or a storm total of 1.30 inches and the lowest temperature during the snow was 33.0 °F so snow was melting during the total period of snowfall.|
|10||Jan.||28th||0.1|| Event 7
|No||Snow flurries that started at 0905 and snowed 0.1 inches before changed to rain by 0950 and ended by 1050.|
|11||Feb.||10th||0.1||Event 8|| Yes ||It was unusual that it started as aggregate flakes made of many crystals not of the fine small broken crystals as shown by many of the snow events of this winter.|
|12||Mar.||27th||0.2||Event 9||No||This was a minor event, as it was warm enough the snow didn't stick on roads or walks. It was interesting that computer models called for this snow a week in advance when we were having temperatures in the 70's and most pople thought winter was over. This event had some snow, a few snow pellets, and was about 1/3 sleet. Most of VA got less than one inch except locations with higher elevations.|
