Notes on the Weather
Issued at 4:36 pm EDT on Wednesday 15 February 2012.
Recent Events
Isolated showers and thunderstorms were observed over the eastern ranges
yesterday afternoon. These included 13mm at Snowy Range, 5mm at Genoa and 3mm
at High Ridge.
Overnight minimum temperatures were within 2 degrees of the February average in
the east, however in the west they were up to 5 degrees above normal. Minima
typically ranged between 10 and 19 degrees. The lowest temperature recorded was
8 degrees at Mount Hotham Airport. Away from elevated areas, Coldstream and
Omeo recorded the lowest temperature of 10 degrees.
Morning fog and low cloud was reported in Gippsland. Cloud increased over the
west of the State with isolated showers near the western border. Cloud built
over the eastern ranges and Gippsland during the day with isolated showers and
thunderstorms developing in the afternoon. Omeo recorded 9mm in the 6 hours to
3pm from one storm, however most falls were less than 1mm. Winds were light to
moderate northeast to northwesterly with local coastal seabreezes.
Maximum temperatures to 3pm were generally 3 to 10 degrees above the February
average, except for the Northeast where they were near normal. While most
ranged between 29 and 36 degrees, the highest temperature recorded was 37 at
Charlton. Along parts of the coast and at elevation many were in the 20s or
teens, with the lowest just 15 degrees at Mount Hotham.
In Melbourne the temperature ranged from an overnight minimum of 17.4 at 6:27am
to a maximum of 33.7 degrees at 3:22pm. The city gauge recorded no rainfall in
the 30 hours to 3pm today.
Explanatory Notes
A ridge of high pressure will generally persist south of the State throughout
the next week. A high pressure system in the Tasman Sea will be dominant early
in the period directing warm to hot northeasterly flow. A trough of low
pressure will move into western Victoria tonight with isolated showers and
milder southerly winds in the west. The trough will reach eastern Victoria
later Thursday. Afternoon and evening showers and thunderstorms will be
possible near the trough and to its east.
The trough will then remain slow moving through until early next week with
warm, unstable conditions persisting in the east until then. Milder southeast
winds with isolated coastal showers will predominate in the south. Conditions
will be mostly sunny and warm in the north. The milder winds will extend
throughout by Tuesday with some showers continuing in the south, and mostly
sunny and warm weather in the north.
