Notes on the Weather
Issued at 4:26 pm EST on Monday 1 September 2014.

Recent Events
Rainfall in the 24 hours to 9am was confined to the western areas of Victoria
as a cold front approached from the west. Most falls were less than 5mm however
some higher totals were recorded across the southwest of the State, including
9mm at Portland, 8mm at Casterton and Wickliffe and 7mm at Glenthompson and
Cape Nelson.



Overnight temperatures were mostly 4 to 8 above average across the State as a
result of extensive middle/high level cloud and moderate northerly winds.
Slightly clearer skies and lighter winds across the east meant temperatures
across Gippsland and the far northeast were close to average. Minima typically
ranged between 7 and 13 degrees. Lowest in the State was 1 degree at Corryong
and Mount Hotham.



A cold front and associated band of rain moved across western and central
Victoria during the day and reached eastern districts by late afternoon. There
were scattered showers and isolated thunderstorms over western and central
parts following the cold front. Rainfall totals to 4pm were mostly around
5-10mm, with the highest total of 16mm recorded at Mount William. Fresh to
strong and gusty northerly winds were gale force at times over Alpine areas and
shifted cooler, moderate west to southwesterly following the cold front. The
strongest wind gust recorded was 117 km/h (63 kt) at Mount Hotham.



Maximum temperatures were 3 to 7 degrees below average over central and western
districts due to rainfall and the arrival of the cold front. It was warmer in
the east due to the later arrival of the rain band and cold front allowing
temperatures of 2 to 5 degrees above average. Temperatures ranged from around
11 to 15 degrees over central and western parts to 17 to 22 degrees in the
east. Highest in the State was 22 degrees at Mallacoota and Orbost.



It was warm overnight in Melbourne where the temperature didn't drop below 17
degrees until after 5am. The temperature continued to fall throughout the day
as rain tended to showers and winds shifted colder westerly. The maximum
temperature of 15.9 degrees was recorded at 6:00am. No rainfall was recorded to
9am, with around 2 to 7mm recorded over the metropolitan area to 4pm with up to
10mm in the outer east. The city gauge recorded 5.6mm.

Explanatory Notes
A cold front crossing Victoria will move out over the Tasman Sea on Tuesday and
form into a low pressure system off the northern NSW coast by Wednesday. A high
pressure system will cross the Bight on Tuesday and will be centred near
Adelaide Tuesday night. The high will weaken on Wednesday as it crosses NSW but
an associated ridge will slowly cross Victoria on Wednesday and Thursday. A low
pressure trough will then move northeastwards from the Bight across eastern
South Australia on Thursday then over northern NSW on Friday. Another high
pressure system will then move from Bight waters across Tasmania on Friday.
