Pattern is well in place for La Nina

Published by:

Michael,

You are not wrong about La Nina - the pattern is well in place. We have had persistent onshore winds for more than two weeks and this includes widespread thunderstorms on a daily basis across various parts of NSW. I chased on several of those days and got hailstones on most of those chase days. However, this is far short of the hailstone sizes we anticipate at this time of the year. Lets hope December delivers.

Weakening storms with a little lightning Thursday

Published by:

Hi Jimmy,

Weather conditions are remaining persistently uninteresting here on the Northern Rivers with onshore winds dominating with temps around the mid 20s just about every day. Last Thursday we did manage to see some weakening storms with a little lightning, but it was soon back to onshore flow with scatterred cumulus and isolated showers. GFS suggests a low may form off the SE QLD coast later this week which will wipe out the thunderstorm chances for another week.   Until November La Nina type weather patterns were not obvious but they sure have been of late.

Decent chases of late – low wind shear though

Published by:

Michael,

I have had some half decent chases of late despite the poor shear aloft. One of the best days with just slightly improved shear within the period was the 19th November chase event listed at the following link:

 Two magnificent surprise storms coming within the Mt Victoria and Lithgow regions. I observed 4 consecutive days of hailstones although this was one of the better days with hail to about 2cm in diameter where I was with respect to the storm. There have been minor hail drifts as well. Contemplating whether I will be lured back to the chase over the next few days hmmm. Fuel prices are through the roof at the moment.
