Recent Events
A complex low pressure system moving across Victoria brought scattered showers
to most parts of the State on Saturday. Rainfall totals reached 10-25mm across
central and eastern districts, with isolated falls of 25-35mm recorded through
central Gippsland and about the central ranges. Lower-lying parts of the
western districts, as well as most of the Melbourne area, generally saw falls
of 2-10mm. Victoria's far northwest and the easternmost parts of Gippsland saw
only light falls amounting to less than 2mm. The highest rainfall totals
recorded in the 24 hours to 9am this morning were 48mm at Freestone Creek (near
Briagolong), 39mm at Briagolong, and 30.2mm at Glenaladale.



Minimum temperatures were 1 to 4 degrees above the July average across most
parts of the State last night. Only the Mallee was cooler than average, due to
patchier cloud across the northwest; minima in this area were generally 1 to 4
degrees below average. A number of locations recorded the State's lowest
overnight minimum of -1 degree: Hopetoun, Falls Creek, Mt Hotham, Mt Buller,
and Mt Baw Baw. In contrast, the highest minimum was 10 degrees, recorded at
Cape Otway, Wilsons Promontory, and Gabo Island. Most locations dropped to
between 5 and 9 degrees overnight.



Showers continued across Victoria today; isolated through the northwest, but
tending more widespread across central and eastern districts. The South West
and Wimmera remained dry. Isolated and short-lived thunderstorms developed off
the Gippsland coast during the day, and in western parts of the northwest.
Rainfall totals in the Mallee were 1-5mm, but reached 5-10mm across most
central and eastern parts, with isolated totals of 15mm or so. The highest
rainfall totals recorded between 9am and 4pm today were 17.8mm at Sale, 16.6mm
at Mt Useful, and 16mm at Cowwarr Weir. Winds today were moderate
southeasterlies.



Maximum temperatures were 2 to 4 degrees below the July average across northern
and eastern Victoria, but a degree or two above average in the Southwest and
Wimmera districts. The Greater Melbourne area was close to average today. Most
places reached between 11 and 15 degrees. The lowest maximum recorded was 0
degrees at Falls Creek, Mt Buller, Mt Hotham, and Mt Baw Baw. The highest
maximum was 16 degrees at Aireys Inlet, Dartmoor, and Cape Nelson.



Melbourne's temperature ranged from an overnight minimum of 9.0 degrees at
8:40am to maximum of 14.2 degrees at 2:21pm. The city rain gauge recorded 6.8mm
rainfall in the 24 hours to 9am this morning, from showers between noon and
midnight on Saturday. No further significant rainfall was recorded in the city
gauge between 9am and 4pm today, however, most northern and eastern suburbs
recorded 1-2mm since 9am today.

Explanatory Notes
A complex area of low pressure lies over Victoria and New South Wales with a
high pressure ridge to the west. A low pressure system will rapidly develop off
the New South Wales coast on Monday as the high moves south of Tasmania and
extends a ridge over South Australia. The low will deepen over the Tasman Sea
on Tuesday and move slowly eastwards on Wednesday as the high pressure ridge
moves across over Victoria.
