Darwin and parts of the Northern Territory have had their coolest morning since August. A high pressure system brought clear skies overnight to the Top End and much the Northern Territory. This coupled with a relatively mild airmass allowed Darwin to drop under 18 degrees, making it the coolest morning since August. It wasn't only those in the Top End that awoke to a mild start to the weekend. In Alice Springs it cooled to just five degrees, the lowest since October. The mild airmass over the Top End will cool further, preventing the mercury from reaching 30 degrees. Darwin is forecast to reach just 29 today despite the sunny skies. In March it only reached 28.9, however this was due to thick cloud that lingered throughout the day. Should Darwin only reach the forecast 29 it will be the first time it's done so under sunny skies since August. On Sunday Darwin is forecast to reach 30 before warming up to 32 to start the working week.
