On Friday a surface trough will stall through the region producing a few showers during the afternoon.
During Saturday the trough increases in intensity drawing in warm moist winds off the Coral Sea while interacting with a cold upper trough. Scattered showers and isolated storms are expected North from Townsville to Georgetown into the South East Gulf region. Anywhere North of a line from Gympie to Mt Isa will see heavy cloud cover due to the upper trough.
Sunday will be the wettest with widespread rain areas from about Cairns to Rockhampton including the ranges and adjacent inland. We should see 24hr rainfall totals up to 25mm from Sunday to Monday morning. This rain is not expected to reach as far inland as Emerald. Rain will reduce to showers along the coastal fringe during Monday.
Maximum temperatures will be much cooler on Saturday due to cloud cover and especially on Sunday with the cloud and rain mix. North East and Central East districts are going to a top of 18-22C. Next to no rain has fallen from Townsville to Rockhampton during the past 9 weeks so it will be very welcome.
