Use isobars at 4 or 5 mb (hPa) intervals.

Would it be possible to show the pressure with isobars at 4 or 5mb intervals which is the norm for most synoptic maps world wide. I am trying to visually predict the severity of the oncoming storm which is approaching the UK but with the isobars at 2mb (hPa) it looks as we are going to have a hurricane!
