Hi, New here so not sure if I am doing the right thing, but here goes.
A week or so ago(9th Jan?) there was an overnight temperature anomaly as reported by the Nowra station. The overnight low was almost 2 degrees warmer than the other nearby stations, and what my home system recorded, ( don't live that far away)
There had been a local event 20 km/h winds then 77km/h then back to 20. It had rained (8mm). There had been some thunder. Wind was southerly which is usually a lot colder.
Anyone care to venture an explanation?

Not familiar with the area but you can get all sorts of variations in temperature under a thunderstorm. Wind tends to keep temperatures warmer overnight. Some places are just warmer than others, for example local hilltops tend to be warmer overnight than nearby areas because cooler air drains into valleys and hollows.

Actually, the Weatherzone Q&A section under General Weather might be a better place for this sort of thread, but no big deal.
