The stage is set for a fast flowing game to open the State of Origin series tonight. Light winds and clear skies will make it a great game for players and spectators alike with perfect conditions for a night out at the footy. At kick off the temperature will linger around the mid teens with light northeasterly winds. As the game begins to heat up the temperature will cool off, with winds set to turn to the northwest and the temperature to drop to the low teens by full time. For Blues supporters heading out to the game, a warm jacket wouldn't be a bad idea. For Queenslanders traveling south for the game a beanie, snow jacket and gloves are probably best as this average Sydney night will feel more like an early winter night in Brisbane. This cool and stable night is due to a high pressure system lingering over eastern parts of the state. It is set to weaken over the coming days as a low pressure trough moves across the state and bringing some light showers on Friday morning before a high brings drier conditions for the weekend.
