I have managed to find a list of the towns that have experienced the highest daily temperatures since 1 January 2014 through to 14 January 2014 (Courtesy from the BOM / Weatherzone 15/1/2014).
Note:- The highest official temperature recorded occurred at Oodnadatta (South Australia) in January 1960 being 50.7C. That is being challanged but not exceeded.
January 1 Tarcoola (SA) 48.9C.
January 2 Moomba (SA) 49.3C.
January 3 Walgett (NSW) 49.1C.
January 4 Lockington (QLD) 45.7C.
January 5 Emu Creek (WA) 45C.
January 6 Learmouth (WA) 46.1C.
January 7 Leonora (WA) 44.6C.
January 8 and 9 Onslow (WA) 48.7C and 48.2C respectively.
January 10 Learmouth Airport (WA) 46.9C.
January 11 Murchison (WA) 47C.
January 12 Kellerberrin (WA) 47.5C.
There is a claim being made of 50C but not proven at Meka Station (WA) (Not official).
January 13 Paraburdoo (WA) 45.8C.
January 14 (Appears to be Keith in South Australia at 47.2C but not confirmed).
Some extremely hot days but the 50C mark is not broken despite possible claims made. This is similar to what occurred during the January 2013 heatwave.
Cabramurra in the Snowy Mts of NSW at 1,500 metres in elevation - On the 15/1/2014, the weather station recorded a maximum of 29.7C showing that the heat is impacting the Snowy Mts. Observatory Hill (Sydney) close to sea level reached a top of 28.4C due to sea breezes and there is a weather station near Bradleys Head in Sydney Harbour recording a maximum temperature just over 24C. The heat is not affecting the coastal fringe but impacting higher elevations inland to an extent where it is warmer in places of the Snowy Mountains than in Sydney Harbour.
Similar readings have been occurring at Mt Ginnini (ACT) although it has been cooler at Perisher Valley due to elevation.
Melbourne:- The forecast is for 4 consecutive days of 40C which is rare. I am aware of a 1908 heatwave where 5 such days occurred in a row but it is doubtful that this will be broken. It reached 42.8C on the 14 and 42C on the 15 but after 3 pm, a weak wind change to the south did cool the city and much of coastal Victoria. The forecast for Melbourne is 44C for Thursday 16 January.
The current heat episode is strong across Northern Victoria and Southern NSW.
Albury:- The maximum daily temperature for the period 11 to 15 January is 36C, 38.9C, 39C, 41.2C and 41.3C (Already 4 days of 38C plus temperatures and more to come).
Mildura (North West Victoria) for the same period in order follows as 39.3C, 36.7C, 42C, 45.2C and 43.6C (Approx).
Bendigo (Central Victoria) in order of days reads as 35.2C, 35.5C, 38.8C, 43.8C and 42.3C.
Griffith (Riverina of NSW) in the same order 36.2C, 37.8C, 40.7C, 41.3C and 41.8C.
There are some warm nights occurring incuding a minimum of 26.4C at Griffith on the morning of the 14 January but the places reviewed have not experienced excessively hot nights although this may change.
A number of fires have broken out in places due to dry thunderstorms and lightning strikes. I will be in the Snowy Mountains early next week and it will be interesting to see what impact this heatwave may have across the region
