At last, something to chase! It was a long shot but CAPE was forecast at over 1000j/kg so we decided to chase despite there being no cap, no dry mid layer, any shear and dewpoints were also horribly low!! We started the chase at Templecombe, aiming to work our way back towards the New Forest.  It looked rubbish so we decided to head to the high ground of Salisbury Plain where initiation of surface based storms were more likely.

We intercepted a cell and punched the core twice, being rewarded with 10mm hail and torrential rain. However there was much less CAPE than the GFS had predicted and so the updrafts were relatively weak. The storms soon became feathery and dissipated but unusually we weren't far from home!
