week of storms Dec 6 - 13 2004
Sunset Dec 8 and Dec 9 2004.
Stormy conditions persisted around Victoria for more
than a week, due to alow pressure system which remained over SE
Australia for the entire period. While work commitments limited
chasing activities, the stormy conditions also provided some
spectacular sunsets. Mammatus from a storm north of Melbourne on
December 8 provided a picturesque spectacle.
Similarly, December 9 provided another spectacular sunset. These photos were taken at the start of a night time chase.
Saturday December 11 2004 saw an opportunity to
chase, following a shortened ASWA barbecue. I went out with David
Simpson, Jane ONeill and Clyve Herbet. This chase yielded some 135
photos, a selection of which appear below, with comments...
Minutes after departure, taken from the Keilor area -
the sky showed promising signs. I was 15-20 minutes behind the
others, due to dropping some food off on the way.
In convoy north of Woodend, after meeting with the others at Woodend...
Near Marong, west of Bendigo, we encountered this cell with an
Wonder what the locals thought of all those strange people
looking at the sky... ;-)
An updraught developing in the outflow of a decaying cell.
After the first cell started to decay, we proceeded north and
encountered this one between Bendigo and Bridgewater. Didn't notice the
wall cloud in this shot until afterwards. This cell caused some
tree damage and flash flooding in the areas it affected.
Stopped to get a closer look (and a lot more photos) of this

After 20 minutes, the outflow started to become interesting.
We continued northwest to Bridgewater, and then turned east and
stopped again 5km east of Raywood. This put us almost behind the
previously photographed cell.
Looking south to a distant cell in the Ballarat area.
Reports later received indicated severe weather around Ballarat.
Overhead was some spectacular mammatus.
An interesting thing we noticed a bit later was that we had
approached the tail end of the storm from the west, where conditions
had been dry, but there had been a sudden transition from dry to wet
conditions. Note the abrupt end of the wet section of road.
An interesting view of a storm framed by trees.
Less than 2km from our previous dry stopping point, we struck
flash flooding. A local farmer estimated 1 1/2" (around 38 mm) in
less than 3/4 of an hour.
Stopped to get a closer look at the flash flooding.
A cell to the north of our location started to look
interesting. Unfortunately, I had run out of time and had to
return back to Melbourne, leaving the other chasers to take a closer
look. Here's a few shots of the cell.
