Parts of Western Australia's Southwest Land Division will get more rain on Thursday than they've had this year so far.
Witchcliffe in the Lower West has only had eight millimetres of rain since the start of January and is likely to get at least that during Wednesday night and Thursday.
For most of the Land Division it will be the biggest rain in more than two months. Late January was the last time most centres away from the south coast recorded more than a millimetre due to cold fronts staying well south.
The coming rain will be most welcome in the Lower West, Great Southern and Central Wheat Belt, the driest districts in the state so far this year. Corrigin, Lake Grace, Medina and some Perth suburbs haven't seen five millimetres of rain in more than three months. Goomaling has only had 15mm in 2011, its driest start to a year since 2003.
The Central Wheat Belt can expect widespread showers as a cold front covers more ground than any other since January. But only five to 10 millimetres is likely in the south and west of the region, less in the northeast.
The only area likely to gain more than 10mm is in the Southwest and Southern Coastal, where 20mm is possible.
