While I'd much rather see another March 2013, that doesn't mean I wouldn't like to see a similar spell to the one in mid/late March 2012.
I love large diurnal ranges so temperatures in the mid/high teens in the day and low single digit/freezing at night would be welcomed by me.
There's a saying that March can be winter in the shade, but summer in the sun, and I remember 2012 being like that - it was surprisingly chilly out of the sun.
It wasn't all high maxima, either. It only reached around 4C here in thick fog that persisted all day on the 15th, yet it hit the high teens in Gravesend.
I guess that's why I love March; it's variability. It can pretty much have any weather you can think of, and at the same time in different parts of the country.
It's still the month with the largest range between lowest and highest recorded temperatures in the UK, at 48.4C!
If not a cold March, here's to an interesting one, and rest of Spring, too.
