PUNTERS will be looking to back horses with wet weather form as the Bureau of Meteorology predicts between five and 15 millimetres of rain to fall over Grafton today.
Weather duty observer at the Bureau of Meteorology's Coffs Harbour office Alison Skinn said a low-pressure trough crossing North East NSW is to blame.
"Grafton will experience patches of rain throughout today and it will generally make for very uncomfortable conditions," she said.
"Another 10 to 20 millimetres is expected to fall on Grafton tomorrow and scattered showers will continue throughout Saturday."
Ms Skinn dismissed suggestions the wet weather is a cup-day-curse, adding the entire North East corner of the state and surrounding areas are expected to be wet for the remainder of the week.
However, good news is forecast for the Maclean Cup meeting on Sunday with sunshine to make a return for the end of the carnival.
"I'm pleased to say Sunday is looking good weather wise.
"After two days of rain I think a lot of people will be happy to see good weather return," Ms Skinn said.
