The prediction is that it could be weeks or even months before a significant rain event takes place to put a dent in fires impacting the Mid North Coast.
Weatherzone meteorologist Felix Levesque said unfortunately it's too hard to forecast when significant rainfall will occur.
In the early morning of Wednesday, November 13 a southerly wind change hit the Mid North Coast.
Mr Levesque said unfortunately the weather system was not rain bearing.
However he said there was a chance of 1-5mm for the north coast of NSW late in the afternoon on Sunday, November 17, some of which might impact the Port Macquarie-Hastings region.
Mr Levesque said unfortunately there could be another spike in heat next week, which won't help the fire situation.
The forecast for Thursday is thick smoke with light winds tending to the east, north-east.
These conditions and temperatures between 27-29 degrees will continue through until Sunday before a southerly change and chance of a thunderstorm.
Fire crews will be preparing for strengthening wind and temperatures around 30 degrees again next Tuesday.
According to the Bureau of Meteorology, bushfires can create their own weather, generating 'pyrocumulonimbus' clouds and storms.
The clouds can cause dangerous and unpredictable changes in fire behaviour, making the fire more difficult and hazardous to fight.
How storms form from fires:
- A plume of hot, turbulent air and smoke rises.
- Turbulence mixes cooler air into the plume, causing it to broaden and cool as it rises.
- When the plume rises high enough, low atmospheric pressure causes its air to cool and cloud to form.
- In an unstable atmosphere a thunderstorm can develop: pyrocumulonimbus cloud.
- Rain in the cloud evaporates and cools when it comes into contact with dry air, producing a downburst.
- Lightning may be produced and can ignite new fires.
