Thunderstorms have been developing rapidly over the northern and central inland of New South Wales on Easter Sunday afternoon with signs of becoming severe.
The storms initially formed in the Mudgee/Gulgong area and then in the surrounding area to the north and west.
A severe thunderstorm warning was issued at about 2:15pm due to the threat of damaging winds and large hail for the Central Tablelands, North West Slopes and Plains, Central West Slopes and Plains and inland parts of the Hunter.
The low pressure trough causing these storms is becoming more intense with help from cooling air in the upper atmosphere. This trough is slowly moving from west to east, taking the storm potential with it towards the coast.
During the rest of Sunday afternoon and evening, storms will become more widespread and should develop further east, possibly affecting the rest of the Hunter and parts of the Central Coast and Sydney.
Storms will still be a threat in Sydney until about 2am on Monday and until about sunrise on the Central Coast and in the Hunter before the trough takes storms offshore. The rest of the day will be spent under clear skies with help from drier southwesterly winds.
Later on Monday potentially severe storms will develop in northeastern NSW, mainly on the ranges. Together with damaging winds and large hail, flash flooding is also possible.
