cold night in northern QLD, NT, WA
Overnight temperatures were yet again well below normal across most
of tropical Australia. The coldest areas this morning, relative
to normal, lay in a broken band from north QLD through central northern NT
the WA Kimberley.
At the base of Cape York Peninsula, Richmond recorded a minimum of 1.0 while
Georgetown recorded 1.5 at the Airport and 2.0 in town, all between 9 and
11 below average. To the west and just 170km from the Gulf of Carpentaria,
Croydon recorded 5.2 yesterday morning and 5.0 this morning, around 10 below.
Farther west again, across the NT/QLD border and only 40km from the Gulf,
Borroloola's minimum was 3.9, 8 below.
and foggy in southern NSW
Fog continued into the late morning or early afternoon across parts
of the Southern Tablelands, SW Slopes and eastern Riverina today keeping
temperatures well below average. A 1033hPa High sat over the area
today, creating a temperature inversion that trapped not only night-time
cold air but also abundant moisture from the weekend rain. Light winds were
strong enough to stir this moisture into fog rather than allow dew to form,
resulting in deep fog that refused to burn off after the sun rose. It finally
at most Bureau reporting stations by midday, but at Corowa it continued through
the day, with visibility at 3pm still only 300m and its maximum temperature
of 8.0 the coldest, relative to normal, in the nation.
