'Things are set to go crazy': Storm warning issued
UPDATE 4.25pm: THE Bureau of Meteorology has issued a severe thunderstorm warning for heavy rainfall, large hailstones and damaging winds across the Northern Rivers.
Severe thunderstorms are likely to produce heavy rainfall that may lead to flash flooding, large hailstones and damaging winds over the next several hours in the Northern Rivers, Mid North Coast, North West Slopes and Plains, Northern Tablelands and parts of the Hunter districts.
Locations which may be affected include Grafton, Coffs Harbour, Port Macquarie, Taree, Armidale, Tamworth and Moree.
UPDATE 12.20pm: NORTH Coast Storm Chasers forecaster Antonio Parancin said the Northern Rivers is about to experience the first "serious storms of the season".
He issued a map which is valid from 10am today through to 2am tomorrow.
"A very volatile setup exists today as we have two troughs clashing and a southerly change moving up the coast. All in all we are not only expecting thunderstorms today, but we are likely to see some supercells develop, especially in the purple area on our storm map.
"Currently the southerly change is located around Nambucca Heads just south of Coffs Harbour. This southerly will continue to push north into the Northern Rivers around about lunchtime and this is when we should see some small isolated cells develop, especially west of Coffs in the elevated areas, also on the Northern Tablelands and southern parts of the Darling Downs.
"Around 3 - 5pm EDST we will see the southerly approaching places like Lismore and Ballina or very similar. At this time we should already see severe storms on the radar extending from about Coffs all the way to the inland areas and start also approaching areas like Casino, Lismore, Ballina and surrounds.
"This southerly will keep pushing north into the QLD / NSW border areas by the late afternoon / early evening. This is when things are set to go crazy where people in the entire Northern Rivers, SE QLD and Sunshine Coast may see very severe storms if not supercells develop ahead of the southerly even some behind the southerly and will move E / NE."
Mr Parancin warned supercells could contain "giant hailstones, damaging and destructive winds, very frequent lightening, flash flooding and poor visibility."
"Severe thunderstorms are possible also in the red areas on the map, but definitely those in the purple be warned and be warned early in advance.
"Anyone who is thinking about chasing today be warned that supercells are violent and extra caution should be taken."
The Bureau of Meteorology forecast states a "very high (near 100%) chance of showers during this afternoon and evening…a thunderstorm likely during this afternoon and evening, possibly severe".
Temperatures in parts of the region will tip 30C today before drastically dropping to 20C tomorrow.
UPDATE, 11.45am: THE NSW SES Richmond Tweed Region has warned residents that severe thunderstorms are likely on the Northern Rivers this afternoon.
"Heads up Northern Rivers - looks like we're in for more storms this afternoon," they posted on their Facebook page.
"Keep an eye on the BOM radar today and listen for any storm warnings."
Original story: PARTS of the region saw a good drenching with severe storms which brought heavy rain on Monday night.

There's a high chance of showers this morning and a chance of a thunderstorm this afternoon, with the potential another 35mm of rain. Temperatures could also reach 29C.

Yesterday BoM's weather situation read: "A weak low pressure system off the Illawarra coast will gradually move southeast away from New South Wales today.
"At the same time, cold front south of Tasmania is moving northwards and will bring a fresh to strong southerly change along the south coast later today, then along the north coast tomorrow. Winds are forecast to tend east to southeasterly on Thursday and Friday as the high pressure system moves from the Bight to the Tasman Sea in the wake of the front."
