Weather News - Spring seesaw swings in Victoria

Ben Domensino, 20 October 2017

Temperatures have plunged by more than 10 degrees across Victoria today after warm and stormy weather targeted the state on Thursday.

Maximum temperatures were up to 15 degrees above average in Victoria during the last two days as a pulse of humid air from the tropics crossed the state ahead of a cold front.

On Wednesday, Cape Nelson (33C) had its warmest October day in 13 years and Combienbar's 31 degrees was its highest October temperature since 2006.

Thursday was also warm and particularly muggy as a tongue of moisture-laden air swept across the state. Melbourne's 21 degrees at 12:30pm yesterday felt more like 24 degrees due to the humidity.

Fast forward 24 hours and much cooler, drier air behind the cold front made today's lunch break feel considerably different in Melbourne. The city's temperature of 15 degrees at midday was feeling more like 10 degrees due to the air's dryness and wind chill.

Maximum temperatures will remain a few degrees below average in Melbourne this weekend before days start warm up again early next week.

Weather News - Early-season deluge continues in Queensland

Ben Domensino, 19 October 2017

Unusually heavy October rainfall continues to soak eastern Queensland as records tumble along the state's North Tropical Coast.

The mass of rain and thunderstorms that has been inundating central and eastern Queensland since the weekend has slowly shifted north during the last two days.

After setting new October daily rainfall records along the central coast earlier in the week, the heaviest falls have targeted the area north of Townsville during the last 24 hours.

Widespread falls of 100-200mm were recorded along the coast and adjacent inland between Rollingstone and Port Douglas during the 24 hours to 9am on Thursday. The highest total in the area was 431mm at a rain gauge called Moyla Alert, near Cairns.

Cardwell's 185mm during the 24 hour period was its heaviest October daily rainfall total on record and more than three times its monthly average at this time of year. Rainfall observations at this site are available back to the late 1800s.

Cairns Airport collected 135mm in the 24 hours to 9am today, which is its heaviest October rain in six years and close to three months worth of rain at this time of year.

Flooding is still affecting a number of river catchments in eastern Queensland following this week's heavy rain.

Weather News - Sydney ends record dry spell

Ben Domensino, 20 October 2017

Sydney's record-breaking dry spell has come to an end as the heaviest rain in at least 2-3 months soaks parched parks and gardens across the city.

A band of rain associated with a low pressure trough crossing eastern NSW today has brought welcome rainfall to Sydney. Unlike most rain-bearing systems in recent months, this one has failed to avoid the state's capital city.

The city picked up 7.6mm of rain before nine o'clock this morning, which is its heaviest daily total in 11 weeks. Falls were a bit heavier further west, with 15mm registered at Ingleburn and 13mm at Penrith up to 9am.

Today's wet weather comes at the end of an exceptionally long dry spell in Sydney, regardless of how you look at the figures.

Here are some of the standout statistics from Sydney's Observatory Hill rain gauge during the past four months, as of 9am on Thursday:
- 43.2mm between June 20th and October 19th - driest four month period (122 days) in 110 years and the second driest on record (37.1mm in 1907 is the current record). Impressively, the average rainfall during this four month period is around 350mm.
- 76 consecutive days with less than 2mm of rain - longest such spell on record (previous record was 64 days in 1989)
- 0.4mm since the start of September - driest spring to date on record (previous record was 2.8mm in 1989)
- 0.2mm of rain during September - driest September and 2nd driest calendar month on record

Rain will ease in Sydney from this afternoon as the trough moves further north, allowing drier weather to return for the weekend.
