THIS UNSETTLED WEATHER WILL PERSIST INTO TONIGHT. FOLLOWING THIS, A TROUGH IS EXPECTED TO DEVELOP JUST EAST OF THE BASIN, SO THERE IS A SLIGHT RISK OF ISOLATED SHOWERS AND THUNDERSHOWERS THIS WEEKEND IF THIS TROUGH DEVELOPS EARLIER OR FURTHER WEST THAN CURRENTLY EXPECTED. A MORE SIGNIFICANT AND MATURE LOW PRESSURE SYSTEM IS EXPECTED TO BRING RAIN INTO THE REGION FROM THE SOUTHWEST ON MONDAY NIGHT AT THE END OF THE FORECAST PERIOD.
