No warnings for Queensland
Forecast issued at 4:30 pm EST on Wednesday 4 May 2016.
A weak ridge extends along the east Queensland coast. A new high pressure system will develop over the southwestern Tasman Sea this evening and then strengthen as it shifts slowly east towards New Zealand during Thursday and Friday, reinforcing the ridge over the Queensland coast. A series of weak upper troughs will move east over central and southern Queensland during the next few days. A weak surface trough will track slowly west over the interior during the next few days. A more significant trough system and associated rain band is then expected to move into southwestern Queensland during Sunday.
Forecast for the rest of Wednesday
A medium to high chance of showers and isolated storms over the southern tropical inland and central coast. Mostly fine about the Peninsula and North Tropical Coast districts with just the slight chance of a shower near the coast. The slight to medium chance of showers elsewhere north of about Burketown to Rockhampton with possible isolated storms. Fine and mostly clear in the south. Light to moderate southeast to northeasterly winds, tending moderate to fresh east to southeasterly about the east coast.
Thursday 5 May
The medium to high chance of showers and isolated storms developing over the southeastern tropics and central coast. The medium to high chance of showers about the northeast tropical coast. The slight to medium chance of showers over remaining areas north of about Century Mine to Yeppoon, with possible isolated storms inland. Just the slight chance of a shower extending into the Central West district. Fine and mostly sunny elsewhere. Light to moderate southeast to northeasterly winds, tending moderate to fresh southeasterly about the east coast.
Friday 6 May
The weak surface trough will track a little further west over the interior as the ridge along the east coast continues to build. The slight to medium chance of showers and possible storms will extend from the southern tropical and central coasts into the central west and northern Warrego. The medium to high chance of showers will persist about the northeast tropical coast in the onshore wind flow, with the slight to medium chance of showers extending west to the northwestern Peninsula. Winds will also tend more onshore along the southern coast with the slight chance of a shower developing. Fine and mostly sunny conditions are expected elsewhere. Warm conditions will persist across much of the state.
Saturday 7 May
A significant trough system will move east over Western Australia, gradually extending a cloud band into southwestern Queensland with some patchy light rain developing, increasing over the far western Channel Country during the evening. An onshore wind flow will result in the slight to medium chance of showers about the east Queensland coast and nearby inland, more likely in the northeastern tropics. The slight to medium chance of showers and possible storms will extend over the western Gulf Country. Fine and mostly sunny conditions are expected elsewhere. Warm conditions will persist across much of the state, particularly the interior.
Sunday 8 May
The trough system will move further east into western Queensland, extending a rain band with isolated storms east through western districts, particularly areas southwest of about Urandangi to Bollon where some moderate to heavy falls are possible. The slight chance of a shower or storm will extend further east into the northwest and central west of the state, more likely about the western Gulf Country. The ridge about the east coast will start to weaken, with just the slight chance of a shower expected, increasing to a medium to high chance about the east tropical coast. Morning temperatures will be well above the May average over western Queensland under the cloud band.
Monday until Wednesday
The trough system will most likely weaken as it continues moving east through the outlook period. The cloud band should become quite skinny and patchy during Monday, with patchy rain and some showers expected with its passage. The surface trough should generate some showers and storms near and to its east, particularly over central districts and the northern inland during Monday and Tuesday. The trough should then contract off the southern coast during Tuesday and off the remaining east coast early Wednesday. A cooler, drier airmass will extend through the state in the wake of the surface trough.
The next routine forecast will be issued at 4:30 am EST Thursday.
