October 2012 was marked by warm temperatures and high rainfall. The precipitation deficit that has been with us is now ended with the abundant rainfall received this month. It certainly will be remembered for Hurricane Sandy and, thankfully, the relatively minor effect that it had on our region.
The average high temperature was 58.4 degrees and the average low was 41.2 degrees giving us an average of 49.8 degrees, 3.7 degrees above normal and the 2nd warmest on record (30 years of records here). 'The warmest October on record was 2007 with an average of 52.2 degrees, and the coldest was in 1992 when the average was a chilly 41.7 degrees. The highest temperature, 73 degrees, was recorded on the 5th and the lowest, 21 degrees, was recorded on the 13th. The first frost recorded here in Riparius was the 21 degree reading on the 13th. Our average first frost is September 26th but this is the 11th year in a row when the first frost has occurred in October. The last time our first frost occurred in September was on September 18th in 2001.
Precipitation for the month was 6.14 inches, 2.02 inches above normal and the 6th highest on record. The greatest amount, 9.21 inches, was measured in 1995 and the smallest amount, 0.39 inches, was measured in 1994. There was precipitation on 17 days, with the greatest amount, 3.27 inches, measured on the 19th and 20th. Our seasonal total is now 36.07 inches, 0.88 inches above normal and the first time this year when our seasonal precipitation has been above normal. This has greatly helped to restore ground water that has been lacking since last Winter's very low snowfall. October has had measurable snow (0.8 inches last year) but only a trace this year.
The river reached its highest level, 6.78 feet, on the 20th and its lowest level, 3.35 feet, on the 12th.
