2010 weather: snow, heat but not much rain
On Feb. 23, 2010 a surprise fiveinch snow blanketed Rockdale, taking its place in weather history as one of the top half-dozen snowfalls in the 86 years official weather records have been kept locally.
Two days previously Rockdale’s high temperature was 77 degrees.
Two days after the snow Rockdale’s high was 64 degrees. Needless to say, the snow didn’t stick around very long.
MILD (SORT- OF)—Not many places would term a summer with 30 highs of 100 degrees or more, peaking at 108, as “mild.”
But Rockdale is one of those places.
Even though there were 30 days with highs of 100 in the summer of 2010, it paled in comparison to the previous summer.
In 2009, there were 62 highs of 100 or greater and 19 of them were 105 or hotter.
Highest temperature of 2010 was 108, recorded on Aug. 23.
August was the hottest month with 22 consecutive days of 100 or higher temperatures.
There were no 100-degree highs in September.
BRRRR—On Jan. 9, the mercury dropped to 14 degrees, the coldest temperature recorded in Rockdale since a 13-degree low in 1996.
The winter of 2009-10 then warmed up for a month with six highs in the
60s and 16 in the 70s.
Then it snowed five inches.
DRY YEAR—The year just past was the second driest in the past decade with just 24.21 inches collected in the U. S. Weather Service rain gauge at KRXT-FM.
(In 2008, only 15.09 was recorded.)
The 2010 total is well below the 10- year average of 33.13 inches and the
86-year-total of 33.23 inches.
“Wettest” month of 2010 was September when 4.21 inches fell. Since September, Rockdale’s total rainfall for 2010 was 1.53 inches.
Driest month of the year was October with a virtually
6A nonexistent 0.06-inch recorded, the driest single month in the past 10 years.
There’s definitely a dry trend in recent years. Even though the extremely dry years of 2010 and 2008 were separated by a more “normal” 33.58 inches of precipitation in 2009, that’s a bit misleading.
About half the 2009 total fell in two months, September and October.
In thir teen of the past 36 months Rockdale has recorded less than one inch precipitation.
In eight more months, rainfall total has been between one and two inches.
Five of the last 10 years, rainfall has been less than 30 inches.
Record dry year was 1949 when just 14.89 inches fell. There are unofficial reports of no rainfall at all in Rockdale for more than a year between May, 1924, and September, 1925.
