Hi Jimmy, i’ve been thinking about that as well and about what a typical La Nina breakdown looks like in regards to thunderstorm activity. If it leaves us with higher than average humidity levels we could be in for a stormy march/april period this year when more signifcant upper troughs start returning?

Absolutely Jeff. However, sometimes you don’t have to wait that long. Consider the last major La Nina event at this time of the year:
1990 March 7th March Major hailstorm and likely supercell hits the Hawkesbury region including Windsor
March 18th 1990 – Supercell hits the southwestern Suburbs to Auburn / Libcombe to Dee Why corridor. Major damage into the hundred of millions of dollars of damage.
1991 January 21st 1991 – Major hailstorms and severe microbursts in the northern suburbs from Kelliyveille through to Turramurra and St Ives and Kuringai National Park encountered extreme microbursts. The cost of this disaster ran into the hundreds of millions of dollars making it the costliest disaster before the 1999 Sydney hailstorm. Earlier the same day as part of the initial system, an extraordinary hailstorm with potentially extremely giant hail demolishes the Oakdale area.
1992 Major hailstorm in the Toongabbie to Wentworthville area February 12th 1992. Unconfirmed reports but reports of very large to giant hail in this event!
How is that for a list!

Bring it on!!! I’m getting really excited after last years second season ended up being a complete storm drought for us and i’m itching to capture some high contrast supercell panoramas.

Some storms today along the ranges between Cooma and Bombala and into Victoria. The mega cap didn’t stop initiation along the seabreeze front and they had a severe storm warning for flash flooding and large hail. There might have been some small hail but more than likely the biggest danger was micro bursts from high bases.
Tomorrow it looks set to fire along the central coast tomorrow and there is already popcorn convection this afternoon in western Sydney.
