WeatherEAST COAST LOW TO FORM
A large cloud band is making its way across the region delivering widespread rain to most of the broadcast region tonight. It is very welcome inland across the NW and New England. Only light to moderate falls will be record though.
Tomorrow, Thursday the 23rd an east coast low will begin to develop. This is going to drive showers and rain periods onto the coast with heavy falls likely. The first areas to be hit will be the Central and Hunter coasts. The low will deepen, intensifying as it moves north hugging the coast. At this point it is set to reach its peak in between Port Macquarie and Tweed Heads Thursday night into Friday with the rain becoming heavy enough to potential cause flooding. Large seas and strong winds will also become a feature.
The good news is there is a very big high, still grown to the west, centering itself over the country. This high will push the low away from the coast quickly on Sat so conditions will ease for the weekend. Isolated showers will linger on the northern NSW coast.
Widespread rain is on the way tomorrow and the large blanket of cloud will make for milder nights but colder days. As the system passes over rain will be widespread and all of the broadcast area is likely to get wet but totals won’t be big, at first.
Once the low’s centre finds the warm sea surface temperatures of the Tasman it will deepen and drive in some heavy rain along the northern NSW coast. Some of that wet weather will spill across the Divide falling as showers. The low will be quickly pushed away by a large high moving in behind the system.
A slow moving, deep low is now spiralling over the Tasman producing a solid swell which will build overnight moving up the coast on Saturday. Combined with the cold, westerly winds will make for an epic weekend of waves up and down the coast for surf lovers.
The air mass is dry so low humidity levels are expected. The lack of moisture in the air allows the temperature to fall quickly once the sun goes down. On the bright side it also helps with day time heating.
Inland morning frosts will become a feature across the weekend.
There is a significant inland rain event brewing, we’ll check that first thing next week.
