October 2010 ended a string of months (nine) with above normal temperatures. The below average temperatures were most likely due to a great number of rainy and overcast days that made it hard to appreciate the fall foliage.
The average high temperature was 55.5 degrees and the average low was 34.3 degrees, giving us an average of 44.9 degrees - exactly one degree below normal. The highest temperature of 69 degrees was recorded on Oct. 8 and the lowest temperature of 24 degrees was recorded on Oct. 19. The first killing frost occurred on the Oct. 10 when the temperature fell to 28 degrees. This ended the growing season, which was about two weeks longer than normal, as the first killing frost has occurred on average around Sept. 26. There were 623.5 degree days bringing our seasonal total to 876.5.
Precipitation was the big story of the month as 8.93 inches were recorded - 4.90 inches above normal and the second most on record. The wettest October was in 1995 when 9.21 inches were measured and the driest was in 1994 when only 0.39 inches fell. The seasonal total is now 43.52 inches - 8.92 inches above normal. With two more months left in the year to add to the total, we have already surpassed the average yearly total, which is 41.49 inches. Measurable precipitation was recorded on 18 days with the greatest amount, of 1.50 inches measured on Oct. 21. There was only a trace of snow here in Riparius, which fell on Oct. 22.
