Severe storm threat spreads to NSW on Wednesday

 

Thunderstorms will develop over parts of NSW on Wednesday, with severe storms possible in the afternoon and evening.

The low pressure trough that triggered severe thunderstorms in parts of Vic and southern NSW on Tuesday will move further north across NSW on Wednesday. This system is likely to trigger showers and thunderstorms over a broad area of central and northern NSW on Wednesday afternoon and evening.

While NSW is not expected to see a repeat of Tuesday’s high impact weather that cut power to more than half a million customers in Victoria, there is a decent chance of some dangerous storms.

The most likely area in NSW to see severe storms on Wednesday is the eastern inland, including the Hunter and areas west of Sydney. Some severe storms area also possible near the state’s central Coast, including Sydney.

One thing that has been working against storm development is the presence of high cloud on Wednesday morning, which limited heating near the surface early in the day, which reduce the energy available for storms in the afternoon.

However, if enough surface heating occurs in the gaps between these high clouds, storms shouldn’t have any trouble developing in the unstable atmosphere over eastern NSW.

Anyone that will be doing school pickup or commuting in eastern, central or northern NSW on Wednesday afternoon should check the radar and latest warnings before heading out.
