Notes on the Weather
Issued at 4:30 pm EST on Wednesday 26 April 2017.

Recent Events
Rainfall was reported from all districts of Victoria in the 24 hours to 9am
today, resulting from shower activity during Tuesday, then a rain band
extending eastwards this morning. Rainfall totals typically ranged from 5mm or
less over the Mallee to 5 to 20mm over much of the State and reached 20 to 50mm
about the northeast ranges and also eastern parts of the central district. The
highest recorded was 55mm at Mt Buffalo Chalet, followed by 46mm at Mt Hotham
and Hunters Hill, and 43mm at the Yarra River near Chandler Hwy and Berringama.



The rain band contracted eastwards and cleared eastern Victoria today, but
showers and isolated small hail persisted in it's wake, mostly over southern
Victoria. There were also isolated thunderstorms over central and eastern
districts. Rainfall totals in the 7 hours to 4pm this afternoon were mostly
confined to southern and mountain areas and mostly 5mm or less - the highest
reported was 14mm at Mt Baw Baw, followed by 10mm at Mt Donna Buang and Yarra
Grange, and 9mm at Wallaby Creek and Thomson-Yarra Divide.



It was mostly cloudy overnight, with northwesterly winds increasing from the
west ahead of a cold front that shifted winds fresh and gusty southwesterly.
Overnight minimum temperature were generally near the April average and mostly
ranged from 6 to 10 degrees. The lowest recorded minimum was -1 degree at Mt
Hotham, Mt Buller and Mt Baw Baw.



Today was partly cloudy with fresh to strong and gusty southwest to southerly
winds extending throughout. The strongest wind gust recorded was 106km/hr at
Wilsons Promontory, followed by 91km/hr at Mt William, and 87 km/hr at Cape
Otway and Yarrawonga.



Maximum temperatures were generally 4 to 9 degrees below average for April and
mostly ranged from 12 to 16 degrees. The highest recorded maximum was 19
degrees at Mallacoota, while at Mt Buller the temperature did not get above 0
degrees.



In Melbourne the temperature ranged from 10.1 degrees at 7:19am to 14.5 degrees
at 10:08am (the coldest day since the 23rd of October last year). There was
20mm of rain recorded in the city gauge in the 24 hours to 9am this morning,
then a further 0.6mm in the 7 hours to 4pm this afternoon.

Explanatory Notes
A strong cold front moved over Victoria this morning. A cold, strong and
unstable southwesterly airflow in it's wake will moderate on Thursday as a
large high pressure system develops over the Bight. The high will then drift
slowly towards Victoria, maintaining a cool southwesterly airflow across the
State then extend a ridge over Victoria on Saturday.
