When Jones commenced his long-range forecasting he received financial aid from the Queensland Government and he moved to Brisbane, but in 1934 he returned to Crohamhurst to build an observatory, receiving aid for this purpose from the Colonial Sugar Refining Co. Ltd.

In 1942 the Long-Range Weather Forecasting Trust, a non-profit body, was established by organisations within primary industry, (with further financial assistance from the Queensland Government) to enable Jones to pursue his researches at Crohamhurst.

It is stated that among Jones's most spectacular forecasting successes were :

1. In 1933 he forecast the Riverina drought of 1936;


2. In 1938 he predicted to within an accuracy of one day, the fall of August rains that ended a serious water shortage in Sydney; and


3. In 1944 he predicted heavy rains that fell in New South Wales and Queensland in 1950.
