Thunderstorms and heavy rain are expected to drench drought stricken parts of New South Wales this afternoon.
A severe thunderstorm warning has been issued for flash flooding, heavy rainfall and damaging winds in the state's Central West and southern areas.
The weather bureau is predicting 30mm or more of rain will fall across the state's north-west, Northern and Southern Tablelands and Central West Slopes and Plains.
Forecaster Katarina Kovacevic says it is likely these regions will record decent falls.
"I feel like it's a very good chance," she said.
Sydney is also on alert for a solid downfall
"I'd say 20 to 30mm widespread. It's a good soak".
The heaviest rain is likely to hit north-east New South Wales where the bureau says levels could go even higher.
The state's Rural Fire Service is on alert for the risk of lightning sparking new fires.
