A sharp upper trough is expected to drop 500 hPa temps to -20 over the Northern Rivers this afternoon. It's effects can already be seen with showers and storms just off the NSW coast.
There will be no capping so we may end up with clutter and showers through there are good chances of some hail about.
We really need the rain as the dry season has been ridiculously dry this year - well over 3 months of barely any rain.
