The British weather is renowned for its remarkable twists and turns and this summer is no different. It switches with ease from storm and tempest to humid, sultry heatwave.

So far summer 2014 in the Anglia region has seen hail storms, flash floods and funnel clouds, the twisting turning fore-runners to full-blown tornadoes. But alongside that there has been warm, dry and sunny weather.

We are almost halfway through the summer months of June, July and August and up until the torrential downpours of Sunday, the summer in the Eastern Counties had been drier and sunnier than average.

Temperatures have been around normal for a British summer in East Anglia but this week they are set to soar and could perhaps reach 30°C (86°F) or higher.

That could also bring explosive side-effects by triggering more thunderstorms later on Thursday and Friday.

Totting up the figures for the summer so far in the Anglia region, by 10am on Sunday 13 July it had been drier and sunnier than normal.

While some places would have been considerably wetter and some drier, the rainfall total averaged across the region was 63 mm. Normally by this time in the summer we would expect to have seen 74 mm.

The sunshine total is only marginally higher than average. From 1 June to 12 July there had been 279 hours of sunshine compared to the average for that period of 271 hours.

Between the downpours and the thunderstorms over the weekend of 12/13 July, it was very warm with temperatures getting up to 25°C/77°F.

The hottest day of the year so far in the Anglia region was on 4 July when it reached 28.7°C at Writtle in Essex and Weybourne in Norfolk.

That could well be topped in the coming week as hot and humid air floods in from the continent.
