Notes on the Weather
Issued at 4:30 pm EDT on Tuesday 22 January 2019.

Recent Events
Low-level cloud about the coast thickened and pushed further over the coast
overnight, with fog patches developing across the south as well. No significant
rainfall was recorded in the 24 hours to 9am today.



While the Southwest district saw minimum temperatures within a degree or so of
the January average overnight, the rest of the State was generally 3 to 7
degrees above the average. Minima ranged from 10 degrees at Mortlake and
Westmere to 22 degrees at Mildura, Swan Hill, Walpeup, and Albury-Wodonga. Most
locations north of the ranges dropped to between 15 and 19 degrees, with
temperatures on and south of the ranges generally between 11 and 15 degrees.



An extensive area of low-level cloud gradually contracted to the coast during
the morning, thinning and breaking up further during towards midday. While
mostly clear and sunny conditions prevailed across western Victoria today,
convective cloud formed across the east during the afternoon, with showers and
storms developing. These produced 9.8mm of rainfall at Albury-Wodonga within
half an hour, as well as wind gusts to 96km/h. No other significant rainfall
was recorded in Bureau gauges since 9am today.



Maximum temperatures were above the January average across most of Victoria
today. Generally, maxima exceeded the average by 8 to 11 degrees. A sea breeze
developing late morning kept temperatures about the coast and through the
Melbourne Basin generally only 0 to 5 degrees above the average. Through most
of northern and western Victoria, temperatures rose to between 35 and 42
degrees. Through the southern and eastern parts of the State, maxima were
generally 26 to 33 degrees. The lowest maximum temperature recorded before 4pm
today was 21 degrees at Cape Otway, and the highest maximum was 43 degrees at
Swan Hill.



In Melbourne the temperature ranged from a minimum of 19.0 degrees at 1.53am to
a maximum of 26.0 degrees at 3:40pm. The city rain gauge recorded no rainfall
in the 31 hours to 4pm today.

Explanatory Notes
A high pressure system over western Bass Strait extends a ridge to another high
located over the Tasman Sea whilst a low pressure trough over inland Australia
extends southward to northern Victoria. A weak cold front will cross Tasmania
Tuesday evening as a new high forms over the Southern Ocean, with the high
passing to the south of Tasmania Wednesday night. On Thursday a deep low
pressure system over southern WA will enter Bight waters and slide southeast,
with an associated trough approaching the western Victorian border at night.
The trough will cross the State on Friday.
