A stormy set-up will light up the skies over New South Wales over the coming days.
A slow moving low pressure trough with linger over the state bringing storms and a few light showers to the southern and western parts of the state today.
On Wednesday, the trough will intensify as it fills with tropical moisture as it slowly creeps further east. Due to the high moisture levels, a strong upper-level jet and a pool of cold air in the south, any thunderstorm that develops brings the risk of damaging wind gusts, flash-flooding and hail.
Residents of the Upper Western and South West Slopes should see the pick of the rain tomorrow with up to 15mm expected but isolated falls of 30mm or more are possible. These storms may extend into parts of Sydney during Wednesday afternoon and into the evening.
By Thursday and Friday, central and northwestern NSW will have its turn for the stormy activity, with showery conditions for large areas of the coast.
Conditions will be a little soggy for large areas of NSW on Saturday, including for Sydney's Mardi Gras goers. By Sunday, the heaviest falls will be mostly confined to the coast.
Looking further ahead, there may be a brief respite in the showers and maybe even enough time to do some washing. By early next week, a newly developed trough will kick off showers ans storms again in western NSW.
