It is expected that England Head Coach Stuart Lancaster will request for the roof on the Millennium Stadium to remain open during their Six Nations clash this weekend.
Warren Gatland has already turned up the heat claiming he wants to see the roof closed to help build up the atmosphere in Cardiff on Friday night.
Both parties must agree to having the roof closed before the game however, meaning England ultimately hold the trump card in this situation.
“We have got a decision to make by the close of play today and we are going to wait for the latest weather forecast later on,” Lancaster said.
“It looks like it is set fair and if it is, then we will probably want it open.”
England players have admitted that they struggled to cope with the febrile atmosphere two years ago when their Grand Slam hopes were crushed in a 30-3 defeat and if the roof is open the sound is likely to be less oppressive on Friday.
England’s current record with the roof open since February 2001 is played six, won three, lost three at the Millennium Stadium and in contrast the red rose side have lost two of their three matches when the roof has been closed.
The only victory came in 2011 when Chris Ashton scored two tries in a 26-19 win, with England also losing 27-18 in March 2007.
