* Precipitation Description: Light, moderate and sometimes brief periods of heavy snow fell throughout the event.
* Total Precipitation: 1.5″ of snow (unconfirmed due to wet snow ratios and quick melting by the time I got home (1 PM), will use airport’s measurement in lieu of any actual measurements in Church Hill).

* Comments: A rain/snow mix started shortly after 8 AM. The precipitation fell as a moderate rain/snow mix through most of my commute to work. By the time I reached the Courthouse area of Chesterfield, snow was quickly accumulating on all surfaces, even the roadways. Snow was wet and heavy, flakes were incredibly large as well. Reports of thunder snow were reported throughout the metro area in the morning. Snow remained heavy until 9:30 AM and became moderate to light in intensity for the rest of the morning. Snow and rain/snow mix occurred throughout the rest of the morning and afternoon hours. Accumulation of snow essentially stopped around 10 AM as temperatures climbed to 37 and snow began melting. Precipitation was spurred by an upper level low that transferred to a surface low on the Virginia/NC border. The NWS was forecasting little in the way of snow for the metro area and scrambled early in the morning with Winter Storm Warnings and Advisories for the region. Areas in western Chesterfield and Henrico saw upwards of 5” of snow from the event. Areas east and south of town saw much less. The airport reported 1.5” of snow.
