Storms were expected in the region near Newcastle today but one particularly serious storm complete with hook came through the Sydney region today making two days in a row of supercells!

  • Yep, way too late on the warnings for Sydney basin AGAIN – what is wrong with their procedures?

    Looking forward to some photos and video – lovely structures on radar

    Here is a still of the best Doppler images from today’s storm over Sydney. Very impressive return!

    Here is the corresponding reflectivity image

  • Caught a CG in a shelf cloud near home a little while ago. The storm became very lightning active for about 5 mins but not much either side.

    This taken at Wollongbar, NE NSW

  • Nice daytime bolt Michael – did this storm show anything interesting on radar – any tighter base and you would you think it was cutting in!

    This was one storm I chased from Backtown. I watched cloud towers develop early and decided to drive to William Lawson Park at Prospect to take some photos. From there, I proceeded along the M4 to the Cumberland HWY, then went south towards Liverpool. I managed to intercept the storm at Canley Heights and I parked the car adjacent to a small park at the corner of Arbutus Road and Gladstone Street.

    Shortly after, the core of the storm passed overhead. At first, large raindrops began falling followed by wind gusts then some gales. I observed leaf stripping and small tree branches being removed from trees. The hail core then passed over me droping copious amounts of pea size hail and some larger hailstones (Actual size of the bigger stones not known). I was amazed at the amount of noise it made. At one point hail fall was copious and the larger stones were bouncing off the ground. I observed some hail drifts start forming around trees and fences. The storm cell was quick to pass and I would estimate no more than 10 minutes.

    The photo provided shows the rain and hail falling at an angle.

    Following the storm, emergency service vehicle sirens were heard quite possibly responding to callouts and problems created. I took several photos of the hail on the ground.

    The storm continued ENE and remained compact. A smaller storm cell developed near Parramatta and I managed to drive close to that one. That smaller cell was producing a short sharp rain shower as it tracked east towards the city.

  • Nice video still of the hailstone action. Do you have the pictures of the storm’s updraft there handy? Post them up – love to see them online!

    Here is a photo of the storm cell looking south west as it was building. Taken at Prospect from William Lawson Park. I did see a pileaus cap on it. Shortly afterwards, I chased it down.

    I did see two cumulo congestus cloud towers east of the main updraft area as shown. It was relatively clear further west and north with smaller cumulus clouds evident. This was the cloud tower that caught my interest the most.

    Of note and at about this time, there was a small but weak cell to the north that passed north of Sydney. This appeared to be weak and I did not take much attention to it.

    Interestingly and following the storm event, I noticed that the wind changed to the south east but was light.
