An intense DAYTIME heatwave is about to sweep across South East and Central QLD delivering a period of relentless HOTTER THAN NORMAL conditions for these areas. Above image showing maximums for Wednesday, December 4th 2019 across South East and parts of Central QLD. Above image – Maximums for Wednesday across SEQLD & CQLD.
During the weekend, a surface trough is expected to become situated near the Ranges across South East QLD, bending back through Southern Inland and Central Inland QLD. This will allow for Northerly winds to feed across South East and Central Eastern QLD which is likely to see not only temperatures but humidity increase across these areas. For the ‘true’ heat, you will probably need to head Inland as places like Brisbane, Gladstone and Bundaberg are expected to see maybe 32ºc, where as Ipswich, Gatton and Rockhampton are heading for more like 37ºc.
On Monday, the trough is expected to become situated right along the Coast throughout South East and Central Eastern QLD. This will direct much hotter and drier winds from Inland QLD towards the Coast. The trough is then expected to bounce between the Ranges and Coastline for the remainder of the week which will enable hot conditions to bake areas away from the Coast.
Across the period of Saturday to Friday (7 straight days) Ipswich is heading for 36ºc or higher, with peak temperatures around 38-39ºc. Gatton is heading for 7 straight days of 36ºc+ as well, with only 1 day below 38ºc during that time. Rockhampton will see maximums of 37ºc+ from Sunday to Thursday with peak temperatures around 40ºc.
A heatwave is considered 3 or more consecutive days and nights of 5ºc+ above average – DESPITE it being Summer. Ipswich averages 31ºc for December, Gatton averages 32ºc – these locations are looking at temperature anomalies of 5-8ºc above average for 7 consecutive days. This well and truly fits the criteria. The only exception will be the drier winds will allow for temperatures at night to drop to possibly even below average (around the mid teens). Rockhampton averages 32ºc for December, so 5 straight days of 5-8ºc above average fits the criteria for a heatwave. Gympie averages 31ºc for December, so 6 straight days of 5-7ºc above average fits the criteria. It will be far more pleasant closer to the Coast with maximums in the low 30’s, so it might be time to hit the beach if you want to escape the heat for a while! Redcliffe is peaking at 31-32ºc and the Gold Coast Seaway around 30ºc! Or… you could escape to Inland QLD where cooler South Westerly winds will dominate and produce BELOW AVERAGE temperatures as places like Birdsville sit in the low 30’s for several days.
