Thanks to support from John Deere, these maps are produced as close to real-time after rainfall is recorded at more than 1000 real-time rain stations across the country.
The STIN crop model is used by Agrometeorology Australia to produce a soil moisture ranking map by shire.
Below average rains in October saw yield rankings slide lower over the last month, especially in southern New South Wales and in northern Victoria and South Australia.
Good rains in the first four days of November helped later maturing crops in southern Victoria, but came too late to substantially help crops in New South Wales.
The drought signature (regions showing yields in the lowest 10 out of 100 years) expanded to cover the top two thirds of New South Wales and most of southern Queensland.
Only southern Victoria, the wetter southwest of Western Australia, western Eyre Peninsula and the far southeast of South Australia had modelled yields above median.
This is the final instalment of yield predictions for 2019. Next month we will present our inaugural map of stored soil moisture thanks to continued support from John Deere.
