BBCs political editor was speaking to Jo Coburn on Politics Live from the campaign trail.
Asked about voter turnout ahead of the big day she said: The forecast is that its going to be wet and cold tomorrow.
The postal votes have already arrived.
The parties are not meant to look at it but they do get a hint and on both sides people are telling me that the postal votes that are in are looking pretty grim for Labour in a lot of parts of the country.
Exit polls get released when the polls close at 10:00pm GMT (5:00pm EST).
From your lips to Gods ears.
