I don't have the time (or will) to put in complete summaries for Jan, Feb and Mar, but here is a brief outline.
January 2006: Max 6.6, min 1.4, mean 4.1, precip 30mm, sleet/snow falling 2, snow lying 0.
It was a benign, and rather uninteresting month, and very dull until the final third, which was relatively sunny. The least warm January since 2001.
February 2006: Max 7.1, min 2.0, mean 4.5, precip 22, sleet/snow falling 3, snow lying 1.
Quite similar to January, with an easterly non-event during the last week- temperatures were no lower than average for the time of year! The only cold snap of note occurred on the last day, with a northerly bringing some snow flurries and a dusting of lying snow at 0900. The month was slightly duller than average. It was the least warm February since 2003, and the driest since 2003.
(Note: I say "least warm" because temperatures were, if anything, slightly above the long-term normal)
March 2006: Max 7.2, min 1.4, mean 4.3, precip 57, sleet/snow falling 11, snow lying 5.
It was the snowiest March for snow falling since I started taking records, beating the previous record of 10 days in March 1995; for snow lying it was equal snowiest since 2001. A cold, bright snowy first week was followed by a brief mild interlude. Then after a classic mild vs cold battleground around the 12th, with the coldest day maximum in March since 1996, it was generally cold and cloudy. The sun re-emerged around the 22nd/23rd, then the last week was very mild and unsettled, but not mild enough to offset the cold weather of the first three weeks.
Overall, it was the coldest and wettest March since 2001, but the average maximum was the lowest since 1996. It was slightly duller than the long-term normal, but less so than last year, sunshine totals certainly boosted by the exceptional first week.
