THE Bureau of Meteorology big promise of worthwhile rain over much of Queensland's grain growing area has seriously faded.
While the best falls are still expected to come on Sunday, BOM's eight day forecast shows an even further reduced area expected to receive worthwhile rain.
On Wednesday the forecast showed all of the south east section of the state was set to receive 25mm of rain (see the very bottom map).
On Friday that computer generated forecast had been scaled back, with 25mm rain now only expected in a far less concentrated area (see map above).
The latest mapping will disappoint many graingrowers who now fall outside the "green zone". They had been hoping for decent rain to kick start winter crop plantings and to provide a drink for already deep sown chickpea and wheat crops.
However, there should be some winners. The best of the rain is now expected to extend into parts of Central Queensland, which was only previously expected to receive 15mm.
The western half of Queensland will continue to experience fine and dry conditions.
According to BOM's Queensland forecast a trough and cold front will merge on Sunday, then track east across the southern half of the state.
There will be a slight to medium chance of showers near the trough over the interior during the morning, which will increase to a high to very high chance of showers and rain areas by the afternoon over the eastern interior, reaching eastern districts after midday.
BOM is predicting possible thunderstorms over the east of the state from the afternoon onwards.
Temperatures are expected to be well above average for this time of year, especially minimum temperatures.
