Google predictions suggest a 90% draw chance which basically means that this match is over at this point. Pakistan were lucky to escape here while England will probably be cursing the weather currently.
If 2 days are lost and 2 more days left and it is impossible to see a result in the match, Pakistan still have a wicket left in their first innings and England need a day to reach that score if the weather allows and then a lead so that Pakistan can bat in the second innings and the match is a gone conclusion. Pakistan have some good bowlers and if there were no interruption who knows what the situation would be.
Pakistan may have good bowlers but remember England middle order is extremely strong and Pakistan bowlers were not able to get through them in the last test match. If the match starts, they still will have difficultly breaking through the England batting lineup.
