Severe thunderstorms are predicted to push up the eastern NSW coast this afternoon, sending temperatures dropping after a weekend of soaring heat.
The storms look to be confined to the east of the ranges, north of about Nowra hitting Sydney, Wollongong and Newcastle and reaching all the way up to Lismore.
“There is also the possibility of some supercell thunderstorms developing, most likely for the Hunter and Mid North Coast,” Mr Pippard said.
“These are the most dangerous type of thunderstorms and can produce giant hail (larger than cricket balls), destructive winds (exceeding 120km/h) and intense rainfall (flash-flooding).”
Weatherzone meteorologist Joel Pippard said the wet weather is due to bring “warmth, humidity and instability all colliding along the ranges”.
A southerly is making its way up the coast which is combining with the warm and humid air and causing it to turn into thunderstorms.
In parts of the northwest temperatures could get as high as 40C and mid-to-high 30s for the north coast.
