The Met Office has issued its first snow warning of the season, as Britain is expected to experience icy conditions this week.

On Wednesday, a yellow weather warning for snow was issued for northern Scotland, with snow showers expected to disrupt travel.

This week's weather in Melbourne and Adelaide has been far from average, with unusually high temperatures on Sunday giving way to unusually low temperatures today.

Temperatures plummet up to 15 degrees in Melbourne and Adelaide

Melbourne is 15 degrees colder today than it was on Sunday, while Adelaide is 13 degrees cooler than it was over the weekend, as per 9 News.

According to Weatherzone, the high temperature in Melbourne today will be 19 degrees, compared to the December average of 24 degrees.

The cool change has surprised Melburnians after the weather reached a scorching 34 degrees yesterday.

Meanwhile, Adelaide will only reach a high of 23 degrees, despite the city's December average of 27, and after a high of 36 yesterday.

However, due to a slow-moving heat trough, temperatures are soaring across much of the rest of the country today.

Willare Experiences Minor Flooding

The Fitzroy River's flood peak is currently at Willare, where the river level is nearing the minor flood level (8.00 meters).

There has been no significant rainfall in the Fitzroy River catchment in the last 24 hours, and no significant rainfall is forecast for the next few days.

The Fitzroy River is experiencing minor flooding from Noonkanbah to Willare.

The Fitzroy River at Willare is currently at 8.01 meters and is nearing the minor flood stage and is expected to remain at or near the minor flood stage (8.00 m) on Monday and Tuesday.

As temperatures drop, Britain braces for snow and ice

Snow is also possible in parts of Northern Ireland and north-east England, with the coldest temperatures expected to arrive on Wednesday, as per The Guardian.

Much of the UK is expected to be just above freezing during the day and below freezing at night.

The Met Office predicts that it will remain cold for much of the UK, with more showers falling as sleet and snow across the north, leading to some accumulations of snow on higher ground.

Showers that fall as rain or sleet are more likely in the south.

Forecasts call for mostly fine and dry weather, with sunny spells in the south at times, but with some sharp overnight frosts.

Temperatures, however, are expected to remain cold or very cold across the UK next week.

According to the weather forecast for Scotland, up to two to five cm of snow is possible on lower ground, rising to five to 10 cm on higher ground above 200 meters.

The strong northerly winds may cause drifting and blizzard conditions, according to the warning.

Central, Tayside and Fife, Grampian, Highlands and Eilean Sia, and Orkney and Shetland are all included in the warning.

In a cold snap caused by low pressure in Norway, daytime temperatures are expected to drop as low as 2 degrees Celsius on Wednesday, dropping to -3 degrees Celsius overnight on Thursday.

The rest of the month's forecast suggests that the weather will warm up, but with rain and wind in the south and west.

According to preliminary Met Office data, autumn (September, October, and November) was the third warmest on record for the UK, with an average mean temperature of 11.1 degrees Celsius.

November extended 2022's run of every month being warmer than average, with the first 11 months of the year being the warmest on record for the United Kingdom.

Although it is too early to guarantee that 2022 will be the UK's warmest year, Mike Kendon, from the National Climate Information Centre, stated that the first 11 months have set up the distinct possibility of a record-breaking warm year, with only a very cold December able to potentially influence where the year will eventually sit in the record books.
