Cool weather before heat and potential rain

A subtle change behind a string of hot days is what has caused volatile temperatures across the region, but temperatures will remain at a low level in coming days.

Day time temperatures are soon likely to be warmer than average across the state, but Bureau of Meteorology climatologists say Greater Shepparton is in for a cooler change before the heat, humidity and potential rain sets in next week.

BoM senior forecaster Richard Carlyon said the region would manage to stay dry throughout the weekend and early next week, with a potential front pushing through on Tuesday.

‘‘A strong high pressure system south of the bite is very slowly moving and it’s just drifting towards us, and what it means is that we’re having fairly similar weather for the next three or four days,’’ Mr Carlyon said.

‘‘The next few days are pretty average, before we see showers developing on late Tuesday.’’

While rainfall across Australia for the spring period is showing no particular shift towards a wetter or dryer period, rainfall totals for spring in northern Victoria have been well below average.

Shepparton totals have reached only 8 mm for October, significantly lower than the average of 31 mm with the month almost over.

Mr Carlyon said while rainfall was forecast for the region from Tuesday, it would unlikely reach any significant falls to meet the average.

Across the far northern coast of Australia, as well as the south-east states, daytime and overnight temperatures and likely to be warmer than average in the next couple of months, according to BoM senior hydrologist Paul Feikema.

Mr Feikema said there were a number of climate drivers that tipped towards both dryer and wetter than average temperatures.

After one of the driest and warmest winters on record for much of Australia, he said spring had also started off dry for the majority of the country.

‘‘Some places will have above average, some below depending on the local weather forecast,’’ he said.

‘‘Days and nights are likely to remain above average for large parts of south-east Australia. 

Vegetation that grew in the wet of 2016 is now drying out, raising bushfire potential for many parts of Australia, which we have already witnessed.’’
