Sunday 1 March 2015 saw a significant weather event pass through Eastern New South Wales. In addition to being one of the hotter days this season, a strong southerly change made its way north along the coast and impacted Sydney after 2 pm as a southerly buster.
Early this day, I drove from Batemans Bay back to Sydney always being ahead of the main wind change.
As I was driving north, I constantly observed a narrow band of showers and weak storm cells to the south but tracking along with the change. These were not significant and certainly did not warrant a separate chase.
It was interesting to note that the very strong dry north west winds did not reach Camden.
Cloud towers simply struggled to form and I gave up the planned chase. Following some shopping at Prospect, I was amazed that a high based storm cell had managed to take shape to the south over Camden probably assisted by the wind change. Another cell was trying to develop to the west and a further cell developing to the north of that.
I have limited photos which I still need to work on.
Over Sydney, the wind change reached the threshold of a southerly buster.
At Sydney Airport a peak temperature of 37.9C was reached at 3 pm (Winds were turning from the NW to east at this stage). At 3.21 pm, the temperature had fallen to 32.9C (Easterly winds). At 3.34 pm, a temperature of 24.4C was observed with a peak wind gust of 96 km/h. A similar gust of 96 km/h occurred at 3.39 pm. This has easily reached the threshold of a southerly buster.
To conclude, the 1 March has been a day of extremes considering that temperatures reached well into the 30s, a southerly buster has brought a vigorous wind change on the coast and a series of thunderstorms developed with that wind change.
I will post some storm images as soon as I have finished working on them but any additional reports and photos are welcome at this post.
