Burnham-On-Sea area is experiencing its warmest December for years,
with forecasters predicting more mild weather to come.

mid-day, while the lowest temperature overnight was 12.8°C
Baggs, a Brent Knoll weather enthusiast, said: "The mild
weather that we experienced in November is still with us, and
the mean temperature so far this month is 11.1°C."
average for the first half of December in previous years is 5.2°C,
ranging from 1.3°C for the first half of Decemer 2010 to 7.5°C
in 2013. The current extraordinarily mild spell follows the warmest
November we have recorded."
this point in December we would normally have seen several air
frosts: on average the thermometer here has dipped below zero
on five or six occasions by the 16th. There had been 11 air frosts
at this point in December 2010, but only one in 2011. In the first
half of December this year the lowest temperature we have seen
is 2.3°C there have been no air frosts at all."
with November, the cause of this mildness is a persistent air
flow from the south Atlantic: a conveyer belt of warm, wet air.
Satellite images taken during the devastating rainfall in Cumbria
from the low pressure system 'Desmond' showed a line of cloud
stretching right back to the Bahamas, and as this warm, humid
air rose over the Lake District Fells it deposited rain for hour
after hour. The rainfall total here so far this month is a modest
18.6mm, and apart from the unseasonal temperatures the main effect
of the air stream has been a blanket of cloud it has been
unrelentingly dull and gloomy."
