Will Weather Steal Victory Chances From England In The Second Test?

A superb batting display by Chris Woakes and David Bairstow led a tottering England upper order to a huge first innings lead of 250 with four wickets in hand.
Bairstow finally fell for 93, but at stumps, Woakes was still undefeated at the crease on a 120 - his maiden century in test cricket.

With oodles of bad weather about, can England risk continuing to bat and taking time out of this match on the final two days?
IMHO, however desirable it might be to bat on - there is every chance that this buzzing England attack will dismiss India for under 250, and of course, they could still bat again if needed.
It would be tragic if rain, onto an already damp pitch, were to pitch England into an unmerited drawn game.
