Cut-off low brings welcome rainfall to the Port Macquarie-Hastings

We'll just call it rain.

Weather forecaster with weatherzone Craig McIntosh says the Port Macquarie-Hastings is expected to receive some welcome rain, starting with some possible light showers late Thursday night before continuing with some solid falls throughout the weekend.

The rain is before formed by a unique weather pattern.

A low formed in the Great Australian Bite will split off – forming a split-off low – before moving over South Australia on a north easterly path.

"That low will eventually get to the north west slopes and plains region - around Narrabri - before it begins pushing back down onto the Mid-North Coast," Mr McIntosh said.

"This will see some possibly light showers overnight on Thursday. 

"Those showers will be increasing throughout Friday with somewhere between 5-10mm of rain generally spread throughout the day.

"We should see some heavier falls toward midnight.

"With that low building over NSW on Saturday it will connect with a moisture source from the Tasman Sea and that will create some of those heavier showers you will experience along with the odd thunderstorm.

"It is going to be quite a wet Saturday.

"The coastal fringe could see 20mm of rainfall although some pockets may see a range of between 20mm to 40mm."

Sunday is also likely to see a continuation of good rainfall with 10mm of rainfall possible.

Showers will start to clear by late Sunday afternoon or early evening.

Thursday's minimum temperature will be 2 degrees however light winds and clear skies could see that figure drop a degree or two, Mr McIntosh said.

"The inland parts of the Port Macquarie-Hastings could drop to 0," he added.

Friday's temperature range is 3 degrees to a maximum of 20.

The weekend temperatures will be 6 degrees to 19 degrees with increased humidity noticeable.

Warmer weather is likely to return on Monday with a minimum of 4 degrees and an expected maximum of 22 degrees.
