A lightning show, thunder and a bucketing of hail between the Camden Haven, inland to Kendall and Comboyne hit at around 6pm.

Comboyne experienced the heaviest falls with the storm dumping 1-2cm sized hailstones on Laurieton, Kew and Kendall.

A spokesperson from the NSW SES Camden Haven said properties at Lorne and Batar Creek were hit hard.

She said the outdoor patio at a property at Lorne was "shredded" by the hail.

Members were called to other incidents involving damaged skylights and fibre glass roofing.

The spokesperson said spring hail is unusual, as February is usually the time for storms to occur.

There were reports of good showers at Pappinbarra later in the evening while Port Macquarie eventually got a shower and thunderstorm at about 10pm.

The Bureau of Meteorology issued a severe thunderstorm warning for parts of the Mid-North Coast on Tuesday afternoon which extended as far north as the Queensland border. The warning predicted large hailstones and damaging winds.

Inland, townships around Tamworth saw some storm activity but the rain we've all be waiting for dumped bucket loads south in the Hunter and across the Central Coast.

The Bureau has predicted a high chance of rain across the Hastings on Wednesday, September 18 - up to 10mm - with a top temperature of 22 degrees.
