    1. The average maximum temperature for March was 69.9F with only March 1945 being warmer with 71.0F in the past 115 years.
    2. The average minimum temperature for March was 46.7F, which is now the 115-year record for March. The average minimum in 1945 was 46.2 degrees F.

    4. This March had 19 days that the high temperature was greater than or equal to 70F that tied the 115-year record with 19 days in 1945. Richmond had 8 days of greater than or equal to 80F; only 1945 had more with a total of ten 80F days.
    5. This March had only 3 days that the temperature was 32F or less; the average is 10.5 days. Only 3 Marches in the past 115 years had less. (1945,1921,1903)
    6. Two daily March records were noted - the record high temperature for March 15 is now 86F. The previous record was 82F in 2007 and 1972.
    7. On March 25th the second daily record was tied with the low daily temperature range of 4F, which also occurred 1965.
    8. Only 13 Marches in the past 115 years have had a maximum temperature for March higher than the 86F.
    9. March, with 2.51 inches of precipitation, was the 35th driest in the past 125 years.

The temperatures ranged between a high of 84 and a low of 23 with periods of very warm temperatures during the middle of the month when we had three days with temps at or above 80. We averaged 9.1 degrees above normal for the month and the average high and low for the month were the highest ever recorded at my site. On the precipitation side, the month was 2.23" below normal with only 1.45" measured. We had scattered light to moderate periods of precipitation throughout the month; but the vast majority of the month's rain came on the 2nd with 0.77" recorded. We have now had just 6" for the year which is now 3.4" below normal for the year. We had a trace of snow on the 5th and ended our snow season with 2.6" of snow and well-below the normal. " - [ + - ]
