Storms have been ongoing throughout Victoria over the past couple of days spreading into NSW. Some interesting pulse cells developed with some impressive anvil shields due to deep convection. Temperatures in the upper levels at anvil level have been rather cooler than I have seen it for many years. So the lapse rates in the upper portion of the atmosphere have allowed for some rapid development including the odd overshoot on pulse cells even. This has also enhanced the conditions for hail development once storms can tap into the upper atmosphere. Mid level temperatures have also been rather cool warming up yesterday as the ridge strengthened. We’ll see what happens over the next several days. At least moisture is no issue from now on. Sydney and the North Coast should be in the firing line over the coming days.

The rain certainly spread to SE QLD and NE NSW since yesterday. The heaviest falls have focused on the Bellingen Valley with totals around 400mm at a couple of places. The Orara, Bellinger and Nambucca rivers are in flood. That’s the 5th flood event for the year at Bellingen and Octobers are not exactly renowned for floods!
72mm at my place (McLeans Ridges, NSW) most of which fell between 11pm and 2am. A number of convergence lines were evident and this meant narrow bands of heavy falls and some areas missing out.
Today is the 6th day in a row of thunderstorm activity which has made up for an otherwise poor start to the season.

Storms and rain look to become widespread throughout the day after some localised heavy rainfall in suburbs of Sydney. Most of the activity seem to be centred on central eastern Queensland which hopefully should extinguish some of those bushfires.
The isolated severe storm that affected Coffs Harbour and Sawtell this morning seem to have been mostly heavy rainfall.

It seems there is a hint of thunderstorms beginning to be in the picture from the 22nd October over eastern NSW and lingering for some time. Obviously this depends on moisture availability. GFS has been very unreliable with predictions of moisture particularly inland around the Central West this season as with other seasons. The coastal areas are struggling with moisture but nowhere near as serious. This means Sydney and further north to the mid-north coast are in for a chance of storms over the coming days.
Meanwhile, bushfires continue to threaten communities over northern NSW and Queensland. I am certainly surprised to see Rockhampton during October getting serious fire behaviour. Personally, I have yet to see bushfires mentioned in the news so far north into the tropics. At least though the dust storms have eased for the time being.

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.
