Notes on the Weather
Issued at 4:44 pm EDT on Tuesday 31 March 2015.

Recent Events
The highest recording in rain gauges around Victoria in the 24 hours to 9am was
just 0.4mm at several locations. These recordings are thought to be as a result
of overnight and morning fog and dew. No further rainfall was recorded in the 6
hours to 3pm today.

Overnight minimum temperatures were up to 5 degrees below the March average and
generally ranged between 6 and 13 degrees. The lowest recorded minimum was 2
degrees at Omeo. By contrast the warmest night was experienced at Wilsons
Promontory with a minimum of just 15 degrees.

Morning fog and low cloud patches were observed, chiefly in the southwest and
in Gippsland. Once these cleared the day was mostly sunny throughout Victoria
although areas of smoke haze from controlled burns were observed in southern
and mountain areas. Light and variable winds were observed across the State
with afternoon sea breezes along the coast.

Maximum temperatures to 3pm were up to 3 degrees above the March average inland
but near normal about the coast. Most maxima were in the 20s. The highest
recorded maximum was 31 degrees at Mildura and Ouyen. By contrast the
temperature only reached 14 degrees at Mt Hotham.

In Melbourne the temperature ranged from an overnight minimum of 11.2 degrees
at 7:36am to a maximum of 25.3 degrees at 4:27pm. No rain was recorded in the
city gauge in the 30 hours to 3pm.

Explanatory Notes
A high pressure system over the Tasman Sea extends a ridge across southern
Victoria and is maintaining light winds and settled conditions over Victoria.
After local morning fog patches in the east Wednesday is expected to be another
warm day with freshening northerly winds. A trough of low pressure will reach
the southwest of the State Wednesday afternoon and central areas at night with
areas of rain and cooler southerly winds developing in its wake.

A new high well south of Western Australia will move quickly over Tasmania
during Thursday, with high pressure then being maintained south of Victoria
until after Easter. Humid, mild northeast to southeast flow with scattered
showers and some afternoon thunderstorms are likely through this period,
chiefly in the east, as the trough remains cradled north of this high pressure
system. It is possible that a low may develop near the southern New South Wales
coast early next week, which may produce heavier rain over parts of the east of
the State, however a deal of uncertainty exists about this feature this far out.
