Notes on the Weather
Issued at 4:47 pm EST on Saturday 18 April 2015.

Recent Events
Rain affected all but the far southwest of the State in the 24 hours to 9am
today, with the largest totals reported in the northeast. The highest recorded
totals were 97mm at Falls Creek, 95mm at Archerton and 92mm at Mt Hotham and Mt
Buffalo. Other totals in the northeast tended to be around 30-70mm, while
elsewhere the totals were generally around 5-15mm. An exception was Mildura,
which recorded its second-wettest April day on record with 56mm, nearly 3 times
the April average.



After 9am the rain had mostly cleared from western and central Victoria, and it
continued to contract slowly eastwards during the day. However a cold front
brought showers to the far southwest during the afternoon. The highest rainfall
totals in the 7 hours to 4pm were once again about the northeast ranges, with
43mm at Mt Hotham, 33mm at Falls Creek, and 28mm at Mt Buffalo and Rosewhite.
Totals from the showers in the southwest were generally less than 5mm.



Overnight minimum temperatures were up to 9 degrees above the April average,
and generally ranged between 8 and 15 degrees. The lowest recorded minimum
temperature was 4 degrees at Mt William, while in contrast the temperature only
dropped to 17 degrees overnight at Mallacoota and Gabo Island.



The morning was mostly cloudy over central and eastern Victoria, but sunny in
the west. During the day the cloud tended to clear over central parts of the
State, but increased in the west ahead of the cold front. Winds were mostly
light to moderate west to northwesterlies, fresh to strong at times about the
northeast Alps, and also in the southwest near the front. Wind gusts as high as
113 km/hr were recorded at Mt Hotham during the morning, while gusts in excess
of 70 km/hr were recorded at Falls Creek, Cape Otway and Airey's Inlet.



Maximum temperatures to 4pm tended to be near or slightly below the April
average, and generally ranged between 17 and 21 degrees. The highest recorded
maximum was 23 degrees at Geelong Racecourse, followed by 22 degrees at
Hopetoun, Essendon, Laverton and Melbourne Airport.



In Melbourne the temperature ranged from a minimum of 13.6 degrees at 3:55am to
a maximum of 21.9 degrees at 4:16am. There was 3.6mm recorded in the Melbourne
Olympic Park rain gauge in the 24 hours to 9am, but no further rainfall in the
7 hours to 4pm.

Explanatory Notes
A cold front crossing the State will clear northeast Victoria early Sunday
morning, leaving a cold and unstable southerly airflow over the State. A high
pressure system will cross waters south of the Bight during Sunday and will be
centred just to the southwest of Victoria on Monday and Tuesday as a low
pressure system develops off the central NSW coast. The high will gradually
weaken on Wednesday as the low moves slowly southwards and the next front
approaches the Bight.
