Hunter Valley Storms 30th December 2017

Hunter Valley Storms 30th December 2017

A marginal day with Hunter Valley storms already firing once I had the opportunity to leave. Headed up the freeway and ended up in time for the second round of non-severe though marginally severe storms. The storms seems to not have sufficient energy to really get to the next level.


The storms according to the models were meant to fire late on the Mid North Coast and the first severe warned storm did make to just south of Port Macquarie. The second round of storms fired in the region near Maitland to its north and near Cessnock to its south.

Sydney Storms and Lightning 14th December 2017

Western Sydney sweltered in temperatures up to 43,4C near Penrith. The intense heat provide the energy to break the cap and produce some thunderstorms during the late afternoon into the evening. The Sydney storms and lightning were not severe and the storms moved briskly towards the coast.

These eventually cleared off the coast but not before a display of lightning across the northern suburbs. High based storms are not the best for structure but definitely do offer opportunities for staccato or branched lightning.

The storms and heat are the beginning of a series of warm and thundery days across eastern New South Wales. Unfortunately,higher based storms can trigger lightning strikes with insufficient rain to put out the fires.

It was not until late afternoon before  high based cumulus began to organise with rippled bases to produce storms.

 

Temora Storm Complex 27th November 2017

Temora Storm Complex 27th November 2017

A few of the higher resolution pics of the Temora storm complex from SW of Temora today. A line of convergence occurred near Narrandera. These literally took off as we passed under them. The main core was further south so we took note of its structure. After some time I noted that the precipitation was persistent and we decided to check it out. This lead to the main chase. Consolidated base and inflow outflow interaction. Lightning caused a grass fire with thin plume rising under the updraft. Unfortunately we had to head back and leave a long lived storm complex go!
