Notes on the Weather
Issued at 4:31 pm EST on Friday 22 May 2015.

Recent Events
Showers and drizzle affected southern and mountain parts of the State in the 24
hours to 9am this morning. Most totals were less than 10mm, however there were
numerous higher totals over central and eastern Gippsland and in the Otway
ranges. The highest recordings were 57mm at Mount Wellington, 30mm at Reeves
Knob, 26mm at Mount Useful and Mount Sabine and 21mm at Murderers Hill.



Temperatures overnight were generally within 3 degrees of the May average
throughout the State. Recordings mainly ranged between 5 and 11 degrees. The
lowest recorded minimum was -2 degrees at Falls Creek and Mount Hotham. By
contrast the mildest conditions overnight were experienced at Gabo Island and
Mallacoota with 13 degrees.



Mostly cloudy skies prevailed today over southern parts of the State, however
skies were generally clear further north. Isolated drizzle and showers were
observed in the south with little rainfall of significance noted. The highest
totals in the 6 hours to 3pm were 5mm at Mount Elizabeth and Point Hicks and
4mm at Gabo Island. The remainder were 2mm or less. South to southeasterly
winds were observed across the State and were generally of light or moderate
strength.



Maximum temperatures throughout Victoria were up to 6 degrees lower than
average throughout the State. Departures from normal were least in the north
where sunshine lifted temperatures close to normal. In the south and about the
mountains persistent cloud kept temperatures lower. Most ranged between 10 to
17 degrees. The State's highest maximum was 18 degrees at Mildura, Ouyen,
Yarrawonga and Echuca. The lowest recording was zero degrees at Mount Hotham.



In Melbourne the temperature ranged from a minimum of 9.1 degrees at 4:40am to
a maximum of 14.1 degrees at 11:27am. Just 0.4mm of rain was recorded in the
city gauge in the 24hrs to 9am this morning. No further rainfall was recorded
in the City gauge during the 6 hours to 3pm today, despite some light showers
in a few suburbs.

Explanatory Notes
A large high pressure system south of Adelaide will drift across Victoria
during the weekend before emerging over the Tasman Sea early next week. As the
high moves northeastward, lower cloud should clear the State during the weekend
and conditions will become fine apart from morning fog patches. Some high cloud
will increase from the west Sunday and winds will tend light to moderate
northerly as a weakening cold front approaches from the west.



Winds will remain in the north or northwest and rather mild through much of
next week as a series of fronts slip southeastward over or near Victoria. Cloud
will increase Monday into Tuesday and showers develop in the north and west as
cloud streams across southeastern Australia from the Indian Ocean and interacts
with a cold front. As a low pressure trough moves closer on Wednesday and
Thursday rain will develop across much of the State as tropical moisture is
lifted by approaching fronts. The strongest front will cross the State during
Friday with rain easing to showers following the front and snowfalls developing
about the northeast ranges. Wind will shift colder southwest behind the front.
Some moderate to heavy falls are possible late next week ahead of and with the
cold front about the ranges in eastern Victoria.
