Progs uniformly have it fading in the coming hours. Question is how far east it gets and how quickly it fades. The current development near Ballarat is well ahead of the bulk of the models, so not sure whether this will be short lived and fade, or signal the storms are going to jump forwards. Cells over Melbourne's east have died, as the cirrus blows over and the subsidence ahead of the main event kicks in.
EDIT> Cell just fired over Melbourne's west. Looks hopeful this one will broaden.. Looking at GFS which seems to have the best handle the convergence is just slightly west of Geelong. It's running 50km or more ahead of GFS. The storms are moving quite quick near Geelong, about 40km an hour. Put them in Melbourne in an hour or so if they hold together.
The Sheoaks cell is nasty. Doppler had some very interesting returns on it during last little while. Sheoaks has also seen nearly 22mm in quick time! Definitely also moving more E than SE in my opinion. Will be interesting to see what else develops in the area.
EDIT: That main band does appear to be weakening as it moves closer (as models suggested), but hopefully it can hold itself together.

Feel free to send me a private message if you have any questions.
Avalon footage is giving the impression of mesocyclone development. Doppler suggesting similar. Also a rogue right hander in front of the mothership on radar.
Dopler showing the outflow is running about 30km ahead of the Geelong cluster pushing up new cells as it runs into the synoptic easterly. These mesoscale convergence effects are not usually captured by models, so next couple of hours in central is more or less about the obs.
Explains why the rain is running well ahead of the models.
Still warm and humid here but breezes are picking up in the tree tops. Nice evening to sit in the shed with a glass of red and watch it all happen. Have fun out there people.
Feels like a sauna up here with a humid easterly. Convergence is now aligned through about Melbourne. Should fire in the northeast burbs then towards Kinglake. Of course, being so complex it may do something completely different.
