Its not out of the question that we could be about to rival April 2007 for warmth in terms of the CET mean.
However, we will be doing so under very different patterns:

Note how high pressure was out west of the UK, and when it sunks south there was no high pressure cell out east of the UK.

Breifly, we saw something more akin to the pattern expected during the first 10 days of April.

Very shortly, though, we were back to high pressure out just west of the UK.
Then then got pushed east, but collapses. Beyond that, northern blocking showed its hand:

The point of this is to reinforce my statement about how this year is different to the past four.

Those sum up 2008's April quite well.

2009 fairly well illustrated.

Finally you have last year.
It seems that a strong Greenland high featured for near a week or so during all of these past four Aprils. Also, high pressure was common out west or northwest, only fleetingly getting out to our east, then as a fast decaying feature. Pressure was often not very high south of the UK for more than the odd few days at a time.
So concludes my whistle stop tour of the past four Aprils in order to reveal how things have changed this time around. This is why I believe that the summer will follow a different pattern to the last four, be it a wet one or a dry one.
