Weather Forecast for Shooting

The weather for the day we are planning to film isn't good, but if it's a constant weather rather than changing multiple times throughout the day as this would cause continuity issues. However, the weather is subject to change so hopefully the outcome for the day will be different, as filming in the rain wouldn't be easy as it may cause continuity problems with people getting wet and clothes getting wet. Rain also tends to lead to more traffic in Cambridge, so there would be an increase in traffic and lights from cars my affect the shots. However if wouldn't be so much of an obstacle if we were in a village (Bottisham or Ashden), rather than in Cambridge city center (Brooklands Avenue or Sedley Taylor Road).
