Issued 4pm, Sunday September 24th 2017. The next 6 days across South-East QLD are making the last few look warm at best, as the heatwave enters next level material… Above image: Maximums for Thursday via OCF / BSCH
A surface trough is expected to be situated over South-East QLD and parts of the Wide Bay region every day for the next 5 days at least (Monday through to Friday). This surface trough is going to combine with another surface trough near the QLD / NSW Border which is forecast to draw in hot, dry North-Westerly winds which will see the temperature skyrocket to new levels!
The positioning of the trough is vital as to who gets the high temps… On Monday the trough is expected to start out between Gympie, Brisbane and Lismore. This will mean most areas are going to feel the heat, apart from the direct Coastline. During Tuesday & Wednesday the trough will drift back towards the Ranges a little, which will see some reprieve, although temperatures will remain up to 7ºc above average for some parts. Thursday will be the kicker… the trough is forecast to be situated right along the Coast giving zero sea breeze effect, this along with an increase in winds will see temperatures scorch up to 40ºc! At this stage, EVERY town in South-East QLD is on track to break their September daily record on Thursday. Friday & Saturday will again remain in the mid 30’s to round out the month before warm, but cooler temps on Sunday.
Elevated fire dangers (“Very High” or greater) are expected each day, with very little to zero rain expected during this heatwave period. There is the chance of some very isolated thunderstorms but these are expected to produce strong winds and little to no rain which will only increase the fire potential.
