Notes on the Weather
Issued at 4:30 pm EST on Sunday 1 May 2016.

Recent Events
A cold front moved across the State during Saturday night and Sunday morning,
producing widespread showers and thunderstorms. Some of these thunderstorms
were severe, producing some haill and damaging winds. Most of the State
received falls of 5mm or more, 10-20mm over central and the northeastern ranges
in the 24 hours to 9am Sunday. Some of the higher falls were 43mm at Mongans
Bridge, 42mm at Mt Buffalo, 40mm at Mt Hotham and 39mm at Yackandandah.



Overnight minimum temperatures were generally 2 to 6 degrees above the May
average, although 6 to 10 degrees in the east. Minima mostly ranged between 9
and 15 degrees with the lowest reported being 2 degrees at Mt Baw Baw, 3
degrees at Mt Hotham and Mt William. In contrast the temperature only dropped
to 17 degrees at Point Hicks.



Gusty north to northwesterly winds tended westerly as a low pressure system
over northwestern Tasmania slipped away to the southeast. Showers and
thunderstorms contracted to southern and eastern Victoria. The day was partly
cloudy in the north and mostly cloudy in the south with rainfall in the 7 hours
to 4pm mainly confined to southern Victoria, most totals less than 3mm. The
highest for this period was Wilsons Promontory with 22mm, Yanakie 14mm,
Yarragon 13mm and Balook 12mm. Winds were fresh to strong and gusty, especially
near showers and thunderstorms. Some of the higher gusts were 130km/h at Hogan
Island, 120km/h at Mt Hotham, 113km/h at Wilsons Promontory and 107km/h at
Fawkner Beacon.



Maximum temperatures to 4pm were generally close to the May average, but in the
far southeast they were 4 to 7 degrees above the average. Maxima generally
ranged between 9 and 15 degrees with the highest recorded maximum to 4pm being
25 degrees at Mallacoota and 24 degrees at Gabo Island. Mt William and Mt Baw
Baw could only reach 5 degrees.



Melbourne's temperature ranged from a minimum of 14.4 degrees at 5:44am to a
maximum of 17.0 degrees at 10:05am. 9.8mm was recorded in the city gauge in the
24 hours to 9am today as a result of a band of showers and thunderstorms which
moved across the Melbourne area during Sunday morning. Further showers during
the day produced 0.4mm in the 7 hours to 4pm.

Explanatory Notes
A low over Tasmania extends a cold front over the western Tasman Sea. The low
will weaken and move southeast on Monday as a weak ridge of high pressure
develops over southern New South Wales. The ridge will remain till the end of
the week, as a cold front crosses Victoria from the Bight during Tuesday, and
another front approaches the State late on Thursday.
