Alvechurch amateur weatherman Phil Thomas records the changes.

Following the trend of the three previous months, December was quite mild with no snow reported locally. There were some cold mornings with five air frosts towards the middle of the month, but quite high daytime temperatures for the time of year (13.2C on the 22nd).

December 2011
Mean Max 8.7C   1.6C above average
Mean Min   2.8C   1.3C above average
Mean       5.8C   1.4C above average
Rainfall   66.8mm 96% of average
Sunshine 59.8hours 123% of average

January has continued the same trend of being mild, being the fourth consecutive months with mean temperatures above the 30-year local average. The were a few hard frosts, however,  with three air frosts on the nights of the14th, 15th and 16th.

The only interesting weather measurement was a gust of 63mph on the afternoon of the 5th, the second highest gust measured in the 10 years of wind measurements at my site. The rest of January appears to be much more of the same.

January 2012 (to 21st)
Mean Max 9.1C   2.4C above average
Mean Min   2.3C   1.1C above average
Mean       5.7C   1.7C above average
Rainfall   26.9mm only 40% of average
Sunshine 45.9hours 91% of average

Mean Max 15.0C 1.3C above average
Mean Min   6.8C   1.0C above average
Mean       10.9C 1.1C above average
Rainfall 548.9mm only 72% of average
Sunshine 1421.9 hrs 114% of average

The year was again a warmer year than the long-term 30-year average, with the mean temperature of 10.9C being 1.1C above normal.

February, March, April, September, October, November and December recorded higher than normal temperatures, the summer months unfortunately being the months below the norm.

April was one of the warmest recorded for many years and also one of the driest. The year 2011 was also the driest year in the last 23 years locally.

The month ahead
The forecast into February is for little major change with a less cold month with some changeable conditions, although the weather models are starting to show some colder spells later.

There is an interesting comparison between the weather and temperatures of this and last year.

XMAS DAY 2010         XMAS DAY 2011
Max temp   -1.0c                             Max temp     +12.4c
Min temp   -6.5c                             Min temp     +3.9c
Mean temp   -3.7c                           Mean temp   +8.0c

That’s a difference of 13.4c on the maximum, and 10.4c on the minimum. In meteorological terms that’s a vast variation from year to year. One of the coldest compared to one of the mildest.

2010 was clear and sunny, temperatures remained below freezing all day (an ice day), with 25cms of crisp snow lying. Whereas 2011 was dull and damp with some brighter spells and totally unmemorable.
