The strongest southeasterly wind surge since last Dry Season has swept out any lingering sticky humidity from the summer over a large swathe of the central and eastern tropics. Richmond, Innisfail, Townsville, Camooweal, Mackay, Ayr, Proserpine and Borroloola were just some of the centres to experience their coldest morning since last Dry Season. For Ingham, Ayr and Proserpine, it was the coldest April morning since Nirvana was headline news. Borroloola and Camooweal cooled to about 10 degrees, likely a refreshing change for the notoriously humid towns and the coolest April morning since 1999. Clermont and Alice Springs (not at all near each other) dropped to a three and a half degrees; the resulting frost pockets would have been a far cry from the baking 34 degree maxima and balmy 19 degree night/morning in Alice Springs on Monday. Hopefully, the campers packed their jumpers. The tongue of cool, dry air will move northwestwards over coming days, giving the northwest NT a chance at a sub-20 degree night.
