Today, this city felt 25 degrees. Tomorrow, it'll feel like 5

One Australian city enjoying warmer weather today will feel temperatures dramatically plummet by up to 20 degrees tomorrow.

Melbourne saw a maximum of 28 degrees today, with the "feels like" temperature sitting a little lower, around 25 degrees, due to a combination of winds and rain, according to the Bureau of Meteorology.

Tomorrow, the temperature will drop to a maximum of 13 degrees, but will feel as low as five degrees.

Weatherzone forecasts that it will feel colder than eight degrees for most of the day.

This is due to a low-pressure system and associated cold front moving from South Australia to Victoria.

It will reach eastern districts by tonight, bringing a sudden drop in temperature, winds and showers with it.

Meredith, Winchelsea, Derrinallum, Skipton, Ballarat, Ocean Grove, Frankston and Cowes are also in the firing line.

A cooler southerly flow will then extend over the state tomorrow, as the low moves east towards the Tasman Sea.

The cold front may also cause snowfall in the Victorian Alps for the second time this week.

Rain will be lashing the city pretty much non-stop from this evening until about 7pm on Sunday.

By then, however, the temperature is set to be slightly warmer.

Temperatures are set to reach a maximum of 16 degrees later in the day, but the early hours of the morning will feel closer to five degrees.

Weatherzone said rapid day-to-day fluctuations are fairly common in the springtime in Melbourne.

Temperatures can reach into the 40s in summer, but because a cool change usually follows extreme heat, the average maximum in the warmest month of January is actually 26 degrees.

Similarly, the average maximum for the coolest month of July is 13.5 degrees - similar to how tomorrow will feel.

The maximum temperatures are calculated based on the ambient temperature of the air itself, while the "feels like" temperature is measured by the ambient temperature, humidity, and wind chill to more accurately assess how a person would feel sitting outside in the shade.
