The Bureau of Meteorology is predicting the possibility of rain over the long weekend in the New South Wales south east.
The Bureau says temperatures will begin to rise tomorrow and Friday before moist air moves in for Australia Day.
Cooler days and nights are also tipped for February and March.
Forecaster, Sean Carson says it has been some time since the region received significant rainfalls.
â??Friday night into the weekend and then that's when it starts to get interesting,â?? he said.
â??It looks like a strong southerly change might stall over New South Wales.
â??The potential for showers and thunderstorms certainly ramps up for Friday night and into Saturday.
â??Even though it is a long weekend it could be a wet weekend,â?? Mr Carson said.
Mr Carson says people in the region should be prepared for the wet weather.
â??It is still a bit early to say but certainly the potential is there for decent falls coming our way.â??
