Had work this morning at 6am. Took a break at around 10am, my goodness it was very muggy, and still is as this band of rain begins to move over the area. Have managed to receive a few heavy downbursts last hour or so, but apart from that it has just been spitty rain. I swear I heard one clap of thunder on the leading edge of the band a few moments ago. The risk for Melbourne isn't over yet, however it is diminishing as this band moves through and the cloud thickens up. The eastern parts look like the main area of play for today.
EDIT: And welcome to the forum Amandagorural, it's great to have you here!
VICTORIA THUNDERSTORM FORECAST - DAY 1
For Friday the 12th January 2018
Very humid airmass across Victoria ahead of a trough of low pressure and an approaching frontal system. The trough will move through the state during the day, with thunderstorm activity likely to form on and east of this trough this afternoon and evening. They are likely through central and eastern areas, where severe activity (large hail, damaging winds, flash flooding) is also possible. The eastern parts of the state in particular will face the worst thunderstorm conditions; supercells are possible in this area. Only a slight risk for southwest areas where the trough is generally already moving through.
Melbourne is in with a relatively good risk today for a thunderstorm. The inhibiting factor will be cloud cover.
