Forecast issued at 4:30 am EST on Monday 5 December 2016.
A high pressure system near New Zealand will remain slow-moving over the next few days and will extend a ridge through the Coral Sea and along the central and northern east coast of Queensland. A surface trough will move through southwest Queensland later today and will then move gradually north and eastwards over the Queensland interior over the next few days, likely entering southeast Queensland on Wednesday. A hot airmass is expected to linger over much of the interior of the state during the coming days, whilst sea breezes will ameliorate the hot conditions near the east coast.
Forecast for the rest of Monday
Fine and mostly sunny across much of central and northern Queensland. A slight to medium chance of showers and thunderstorms over southern Queensland, although coastal areas should remain fine and mostly sunny. A slight to medium chance of showers about the far northern Peninsula. Higher than average temperatures persist across most of the state, especially in the southeast, southern and central interior, whilst sea breezes will keep coastal areas somewhat cooler. Moderate to fresh east to northeasterly winds about the east coast. Mostly moderate northwest to northeasterly winds elsewhere, tending westerly over the southern interior.
Fire Danger - Very High in much of northern, central and eastern Queensland.
Tuesday 6 December
The weak upper trough is likely to move slowly further east across far southern Queensland whilst a surface trough will move gradually eastwards across the southern interior of the state and into the southeast interior of the state. A weak ridge will persist along the east coast of Queensland. Fine and mostly sunny through the much of the tropics with only a slight chance of showers about the east coast of Cape York Peninsula. A slight to medium chance of showers and storms southwest of about Mount Isa to Warwick with a slight chance of a shower or storm reaching the southeast coast later in the day. Temperatures will remain well above average across most of the state, especially in the southeast and the southern and central interior, whilst sea breezes will keep coastal areas somewhat cooler.
Wednesday 7 December
A surface trough extending from the northwest to the southeast of the state will remain slow-moving. Showers and storms will again be possible across southern, central and western districts, with the best chance around the southeast quarter of the state. Fine and sunny conditions will continue across the rest of Queensland apart from the slight to medium chance of showers in the eastern tropics and over the far northern Peninsula. Temperatures likely to remain well above the December average for most of the interior and southeast of the state, however temperatures will return close to average in the southwest.
Thursday 8 December
A weak upper trough will move further northeast into the southwest of the state, while a broad area of low pressure will persist through the interior. The slight to medium chance of showers and thunderstorms are forecast in a broad band extending from the northwest of the state into the southern and southeastern interior, increasing to a medium to high chance in the southeastern quarter of the state. The slight to medium chance of a shower about eastern tropical coast and northern Peninsula. Temperatures will return close to the average in parts of western and southern Queensland, however much of the interior otherwise will still remain above average.
Friday until Sunday
The upper trough will push into the north of the state during the outlook period, with a surface trough pushing northeastwards in response. As a result, showers and storms will be possible in a broad band extending from the northwest to the southeast, most likely contracting out of southeastern Queensland by Sunday. Fine and sunny conditions will continue across the rest of state apart from the slight to medium chance of showers in the eastern tropics as winds tend more onshore. Temperatures likely to remain well above the December average in parts of eastern Queensland on Friday, although a cooler airmass is expected to extend through much of western and southern Queensland by Saturday.
The next routine forecast will be issued at 4:30 pm EST Monday.
