19-12-03 Rain

Previous Page

A forecast that changed every 4 hours made life for the BOM difficult. The possibility of a light show from big storms diminished as the system approached, but local heavy falls were still a good possibility. That part of the forecast did not disappoint. Friday the 19th saw Meadows receive 27mm with a downpour in the afternoon that spiked clean off the graph on my WS as can be seen from the image below. It is possible that it was the heaviest rain I have ever recorded!

Another unusual event was the rise in barometric pressure coinciding with the rain downpours. The usual course of events sees a drop in the pressure with such rain events as a trough or front passes. This I have not seen before??? The image below highlights in the green circles the rises.

The rain band on Friday was huge and very widespread. One of the most extensive I have seen for a very long time.

VERY heavy rain periodically hammered those in its path, heaviest falls on the southern ranges.

Saturday gave us a break with warm temps and high humidity. All changed again on Sunday when I awoke to strong wind and VERY unstable skies. Light rain was spitting and a look at the radar confirmed my thoughts that decent rain was about. Adelaide had local flooding and 16mm in a very short time. However the moisture stream was very narrow and the flooding was restricted to a small area. Mt Barker recorded 38mm to 9:00am monday. The winds stayed high and caused quite a bit of damage at home with a tree down and debris everywhere. All up from the 2 events we received 35mm with some spots getting well over 50mm!
