Annual precipitation above normal

Staff Report

Above-average rainfall during June and July has helped Mount Airy maintain a precipitation surplus for the year as a whole, according to weather statistics from the city’s F.G. Doggett Water Plant.

July’s output totaled 5.72 inches, nearly 1 inch above the local average for the seventh month of the year, 4.76 inches.

Measurable precipitation was recorded on 11 of July’s 31 days at the water plant, the city’s official weather-monitoring station. The largest amount for a single day was 1.32 inches on July 28.

June rainfall also was above normal, but by the slightest of margins — 3.87 inches compared to the local average for that month, 3.86 inches. Proportionately similar to July, measurable levels occurred on 10 of June’s 30 days. The largest amount logged for a single day was 1.21 inches on June 20.

Through July 31, Mount Airy received 36.6 inches of precipitation for 2017 as a whole, which is 9.23 inches, or 33.7 percent, above normal for the year.

Temperatures mixed

July was a tad warmer than usual locally, with temperatures averaging exactly 76 degrees for the month. Mount Airy’s norm for July is 75.8 degrees.

The mercury ranged from a monthly high of 93 — which occurred on three days, July 20, 21 and 23, to a 53-degree reading at the other end of the scale on July 31 which took low-temperature honors last month.

In June, the high reading was 89 degrees, logged on June 15, and the low of 48 occurred on both June 28 and 29. The reading for the 29th broke the city record for that date of 49, set in 1970.

All that conspired to make June a little cooler than usual, 70 degrees vs. the all-time Mount Airy average for the sixth month of the year, 72.7.

Weather records have been kept in Mount Airy since 1924.

Fog was noted on two days in July and one day during June.
