The period 25 to 28 January 2015 will be remembered for a number of weather extremes at either end of the scale across Eastern New South Wales including Sydney.
In particular, no less than 6 or 7 varying weather events have occurred during this period in such a short time. They include:-
1 - A significant morning fog Sunday morning across parts of Western Sydney which for me, is the first time I have seen a major fog occur mid summer in mid January. The fog had burnt off prior to 8 am Sunday.
2 - A hot day across Sydney Sunday. The fog across Penrith quickly burnt off only to have maximum temperatures soar to 36C or 37C across large areas of Sydney on the same day. It is determined that this was the second or third hottest day of the summer depending on suburb or location.
3 - Thunderstorms although isolated in nature just to the north of Sydney during late Sunday.
4 - A southerly buster moving north along the New South Wales South Coast late Sunday which was just strong enough to be classified as a true southerly buster. It brought winds to 61 km/h at Albion Park.
5 - Three days of rain that brought significant rainfalls from the 26 to 28 January as well as unusually cool conditions for Australia Day 26 January and Tuesday 27 January in which temperatures struggled to reach 20C across much of Sydney.
This post will document the extremes of weather for that 4 day period because the variations are significant and remarkable and should be recorded.
I have attached a number of images to this discussion under each weather scenario that occurred.
