The outcome of a Test match can so often be dependent on the weather.
Here is everything you need to know about the forecast across the five days of action in Sydney.
What is the latest Sydney weather forecast?
As it stands, there is a strong chance we will continue to see some showers across the next four days of this Test.
There still are hopes, however, that the rain will stay away long enough to avoid more extended delays at the SCG.
Temperatures are expected to be warm for the remainder of the match.
Day-by-day forecast
The Bureau of Meteorology's forecast has outlined the following chance of rain for each day of the fourth Test.
Friday January 7 (Day Three) - Cloudy, with a very high (90%) chance of showers. 0-3mm of rain. Max temperature of 25 degrees.
Saturday January 8 (Day Four) - Partly cloudy, with a very high (90%) chance of showers. 6-20mm of rain. Max temperature of 27 degrees.
Sunday January 9 (Day Five) - Cloudy, with a high (70%) chance of showers. 1-5mm of rain. Max temperature of 27 degrees.
Which Australian Test venue receives the most rain?
Only 43 days of Test cricket have been called off in Australia due to inclement weather, but some cities are bigger offenders than others.
The SCG alone is responsible for 25 cancelled days of Test cricket.

Rick Finlay's 2017 tweet shows this disproportionate statistic, with the SCG adding another lost day of cricket in 2018.
