Hailstones from the hailstorm near Newcastle

Hailstones

Severe hailstorms affected the Hunter Valley region but most storms of more significant severity producing large hail were near the Karuah to Bulahdelah region. Hailstones to 3cm were widespread along this path perhaps larger in the main core as these hailstones were falling predoinantly ahead of the main core in the anvil region.

Supercell

A severe hailstorm on Monday 23rd February exhibited classic supercell structure with very definite hailstones! The structure did not last for long before it went into a slow decline. Nevertheless althoguh Sydney area did not have any storms predicted storms did develop further west. Twice the storm tried to organise before basically sending up an impressive explosive updraft and organising rapidly.

21st February 2009

Several storms were reported with hailstorms rapidly developing near funnel cloud in the form of a dimple almost overhead whilst near Lithgow from a hailstormLithgow initially and also east of Mudgee a little later. There were likely two supercells out of this region. The Lithgow cell had an interesting base – this nice image of a base circulation and dimple of a funnel almost overhead. This coincided with a wind change in the near storm environmental boundary.

This storm eventually moved towards but narrowly bypassed Singleton with very large hailstones. Another severe storm passed in the hinterland west of Muswellbrook – both this and the Singleton storm were likely supercells producing very large hailstones.

hailstormHailstorms Lithgow to near Lake Macquarie. The hailstorm that approached Lake Macquarie was a fast moving storm and dumped hailstones to a diameter measured at 4cm. It most likely was an elevated supercell and was interesting to watch as it altered its local environment suddenly clearing the low cloud as it raced across.

Another sharp right moving hailstorm approached Lithgow from near Mudgee and produced hail damage in Lithgow!

December 21st 2009 Singleton hailstorm

Very large hail was observed as a long lived supercell tracked the Putty Road north of Sydney and hitting Singleton head on causing extensive damage.

Menacing hailstorm

Menacing storm

Severe hailstorms developed over the Putty region exploding to another level regardless of the weaker wind shear. Despite the warmer atmosphere, large hail was observed with microbursts near Jerrys Plains.

January 14th 2010 Supercell Walcha

Lightning Walcha from a hailstorm

Lightning Walcha

High CAPE dominated on this day and although wind shear was relatively weak, the supercell attained excellent structure with deep layer inflow. A nice beaver tail observed for some time before the hailstorm became outflow dominant. Lightning activity was incredible with a few sparkes on power lines observed. Large hailstones to 3cm were observed.

February 27th 2010 Classic Supercells with hook echos!

Supercell hailstorm Mudgee

Supercell Mudgee

Several supercells developed on this day with hook echo featuring on at least 4 of these supercells – never experienced on any Australian radar to this date! Very large hail with the hailstorms was observed smashing windshields in the Portland region.
