December 2011 was
Warm and Dry
After very cold Decembers in
2009 and 2010, December 2011 ended as the 13th
warmest in North Carolina since 1895 according to
the State Climate Office of North Carolina.
Statewide, average temperatures were generally more
than 4 degrees above normal. This is most
evident in daily maximum temperatures where most
reporting stations ranked December as the 10th
warmest, and many (including Charlotte, Greensboro,
Raleigh, Wilmington, New Bern and Elizabeth City)
had maximum temperatures ranked in the top 5 warmest
for all Decembers.
Precipitation patterns varied
across the state in December 2011 ranked as the
driest December since 1895.
Southeastern North Carolina
averaged 3.75 degrees warmer than normal and
rainfall was 2.69 inches or about 23% below normal.
According to the report, While drought isn't a
concern for most agricultural sectors in North
Carolina, water supply recharge is. The colder
months are when North Carolina generally recharges
its groundwater, river, and reservoir supplies.
while the cooler half of the year doesn't
necessarily produce more precipitation across the
state, the nature of rainfall is different.
Widespread storms help to recharge water supplies
more effectively than localized thunderstorms.
The other big factor for winter recharge is the low
evaporation and plant transpiration rates.
During the cold seasons, nearly every drop that
falls goes to recharge. In contrast summer
evaporation rates are so high that much of what may
ball from a single thunderstorm is returned to the
atmosphere within days.
The lack of rainfall in
eastern NC has resulted in drought impacts to river
and groundwater supplies in those areas. If
dry conditions persist, it may also start to impact
winter grain production for growers.
Bladen
County continues to be in a moderate drought.
In
December, Bladen County's average daily maximum
temperature was 62 degrees. Average daily
minimum temp was 38.5 degrees and rainfall averaged
about a half inch.
