No worries Supercellimpact. I admit l have in the past been somewhat critical at times. It wasn't until l tried to understand the weather myself
,that l came to realize the complexities involved in forecasting. LOL
Anyway ..found this excellent article on La Nina returning and its impacts on the US.
I thought a La Nina was just a rain event
but this article describes the havoc a la Nina can cause for hot, cold , wet and dry etc.in the US in particular . I don't know if a La Nina can cause droughts in Australia?
This article was an eye opener for me!.
It is titled
The Return Of La Niña Is Bad News For Drought Stricken Southern USA
Just a few snippets below but go to the link for the remainder of article
La Niña, one of the primary contributing factors to extreme weather around the globe during the first half of 2011, has re-emerged in the tropical Pacific Ocean and is forecast to gradually strengthen and continue into winter.
Forecasters from the National Oceanic and Atmospheric Administration (NOAA) have upgraded their La Niña Watch to a La Niña Advisory.
The strong 2010-11 La Niña contributed to record winter snowfall, spring
flooding and
drought across the United States, as well as other extreme weather events throughout the world, such as
heavy rain in Australia and
an extremely dry equatorial eastern Africa.

Mike Halpert, deputy director of NOAA’s Climate Prediction Center said:
“La Niña also often brings colder winters to the Pacific Northwest and the northern Plains, and
warmer temperatures to the southern states. This means drought is likely to continue in the drought-stricken states of Texas, Oklahoma and New Mexico”.
