From
the continual arctic blasts of cold air to start the year, to the long
standing
oppressive heat of the summer, and the lack of any substantial rainfall
during
the latter half of the year, the weather in 2010 will be remembered
mainly for
the extreme variations in temperature and lack of precipitation that
were
experienced across northeast Florida and southeast Georgia. Overall,
despite a record summer heat wave, the
quick return to much colder than normal weather in December will help
make 2010
one of the coldest years on record across the area.
The
cold start to 2010 can be partially explained by the dramatic shift in
the
mid-latitude jet stream configuration associated with the Arctic
Oscillation
(AO) and the North Atlantic Oscillation (NAO). The switch began on New Year’s Day as an arctic
air mass entered the
region and started what would be the coldest 2 weeks in climate history
across
the forecast area. Most of the climate sites across the area set new
all-time records
for consecutive days with minimum temperatures at 32 degrees or less.
