Parts of QLD have seen their warmest July day in two decades. There hasn't been a warmer July day at Kowanyama since 1995, when the mercury hit 35 degrees. The mercury finally came to a stop at 34.8 degrees this afternoon, only 0.3 degrees from making the record books. At Century Mine temperatures were seven degrees above-average for this time of year, reaching 35 degrees today. For large parts of the Northwest such as Camooweal, Mount Isa, Cloncurry and Phosphate Hill it was the warmest July day in five years, as the mercury reached nine degrees above the July average. In the Central West, it was also the hottest July day in five years for Longreach, Blackall and Winton. The warm spell is primarily due to heat slowly building during the day under sunny skies over the past week. The unseasonal warm spell will linger over central and northern QLD into the weekend. For most places, Monday will bring a noticeable drop in daytime temperatures by three-to-five degrees. Tuesday looks to be the coolest day of the week, with temperatures in the low-to-mid 20's as the cold air from the south finally makes its way over QLD.
