PB weather in 2012 largely warm and dry


Pine Bluff in 2012 experienced its warmest high temperatures since 1953, according to an annual review of the city’s weather and climate released by the National Weather Service forecast office in North Little Rock on Wednesday.

The NWS reported that low temperatures as well as average temperatures for the year in Pine Bluff were the warmest since 1998, although not warm enough to put 2012 on the list of top 10 warmest years for Pine Bluff.

The report noted that snow during the year was minimal, with a trace falling on Feb. 13 and two inches recorded at the NWS Grider Field reporting station between Dec. 25-26 in last week’s Christmas Day snowstorm.

The NWS reported that the two-inch snowfall total for Pine Bluff is below the 3.1 inch historical average for the area.

Rainfall

The NWS reported that Pine Bluff endured below-average rainfall for the third consecutive year in 2012 but was saved from being one of the top 10 driest years on record because of the heavy rainfall that hit the region courtesy of Hurricane Isaac, totaling 12.41 inches during the three day period from Aug. 30 to Sept. 1

Overall rainfall for the year in Pine Bluff was 45.69 inches, according to the NWS, which is 5.46 inches below normal.

Below-normal precipitation for the month was recorded for January, February, March, April, May, June, October, November and December.

The 2012 total for the affected months was 25.45 inches, compared with average of 42.05 inches for the same period.

As of Dec. 25 Jefferson County showed no drought conditions according to the U.S. Drought Monitor.

A swath of counties from far Southeast Arkansas, west toward Union County, then north through Pulaski, Lonoke and Prairie counties, also showed no drought conditions as of Christmas Day.

Large areas of western Arkansas remain under extreme drought condition, however, according to the U.S. Drought Monitor.
