It's not our fault, OK? We just forecast and report the weather, we don't make it.

But that curly band of cloud with the speckled cloud behind it in the Great Australian Bight on the Thursday afternoon satellite pic could play havoc with a few weekend plans.

The good news is that if you live in Perth, Brisbane or Darwin, you can expect a reasonable sort of weekend weather-wise, with next to no chance of rain.

But if you're anywhere near the southeast corner of the country, it's going to get chilly and quite possibly wet as that front in the bight moves northeast.

We can virtually guarantee that this won't be the strongest cold front of the next few months, but it will be strong enough to deliver a taste of winter to many parts.

Sydney has failed to reach 20°C only three times so far this month, but looks set to peak at 18°C on both Saturday and Sunday.

Melbourne is looking at weekend tops of 13°C and then 16°C with the likelihood of showers on both days, especially Saturday.

Adelaide shouldn't get too wet with only the chance of a shower, but both Saturday and Sunday should only reach 17°C.

Hobart will be chilly with tops of 11°C and 14°C on Saturday and Sunday respectively, with showers likely both days.

Canberra will likely miss the moisture from this system, which won't make it past the mountains, but the capital will still feel cold winds, with weekend tops of 12°C and 13°C, and Saturday night looks like a double-doona sort of night with a low of -5°C on the cards.

Some snow is expected on the Victorian Alps and NSW Snowy Mountains too, falling as low as 900 metres by Saturday.
