South-East QLD and North-East NSW are about to enter another round of extreme heat. A warm air mass is forecast to move overhead and combine with a series of troughs to produce significant heating across South-East QLD and North-East NSW specifically.

Models are predicting the proper heat to begin on Wednesday with temperatures likely reaching the mid 30’s across both regions, and the high 30’s across Northern NSW. Thursday the roles are reversed with mid 30’s across the board and high 30’s in Inland parts of SEQ. Friday there is a slight lull in temperatures due to a cool change moving through during Thursday evening, but Saturday is expected to be the pick of the bunch with numerous places likely to exceed 40ºc (Casino, Beaudesert, Boonah, Gatton, Ipswich (possibly)) to name a few, while the remainder climb into mid 30’s. Very warm conditions are likely to remain in place on Sunday, but a vigorous cool change should limit heating.
This increase in heating across the region and the addition of a trough drawing in moisture is likely to trigger thunderstorms during the afternoon and evening each day. Thankfully for those who receive storms, overnight temperatures will be tolerable, but for those who don’t it could take a bit of time to cool down. Minimums overall are likely to remain in the low to mid 20’s for much of the night before rapidly increasing the following morning once the sun comes up.
Heat stress at times will be an issue, and its a timely reminder to slip slop slap (especially over the weekend when families have time to be out in the sun). Drink plenty of water. Look after the elderly, young, pregnant and animals/pets as they are the most at risk of heat stress, and avoid strenuous activity during the middle of the day.
