Australia -- Queensland Weather Update

MELBOURNE - Feb 20/18 - SNS -- The current forecast for the state of Queensland was released by Australia's Bureau of Meteorology.

Weather Situation
An upper low over southern inland Queensland will move slowly northwards through the eastern and central inland from Wednesday through to the end of the week. This feature will extend unstable conditions over much of the state, particularly northern and central districts. A surface trough over western Queensland will shift further west over the next couple of days, resulting in a moist air mass extending over much of the state. A strengthening ridge along the southern Queensland coast will combine with a deepening trough moving west across the Coral Sea to possibly enhance showers about the southern coast and nearby inland later this week, however there is some uncertainty with the evolution of this trough. Hot conditions will focus more through the northwest on Wednesday, while cooler conditions under heavy cloud cover will spread across most eastern inland parts, reaching the northwest by the weekend.
Forecast for the rest of TuesdayShowers and severe storms over the central and southern tropical inland with some heavy falls likely. A medium to high chance of storms over the remaining tropics, more likely inland with possible locally heavy falls. A slight to medium chance of showers and gusty storms over remaining areas east of a line from Urandangi to Windorah to Cameron Corner. A medium to high chance of showers in the southeast with possible isolated storms. Moderate to fresh and gusty northeast to northwesterly winds over much of the state, tending southeast to southwesterly over southwest parts of the state. Winds mostly moderate east to southeasterly over the far southeast.Wednesday 21 FebruaryA high to very high chance of showers and thunderstorms across the central and northern districts. Possible heavy falls about the tropics and northern parts of central districts, particularly inland. Cloudy with patchy rain, showers and possible isolated storms over the southern central districts and Wide Bay. A medium to high chance of showers and drizzle in the far southeast. A slight to medium chance of showers and gusty thunderstorms over remaining areas north of about Roma to Windorah to Camooweal. Moderate to fresh east to southeasterly winds over southern and central Queensland, strong at times off the southern coast, tending light to moderate northwest to northeasterly over northern Queensland. Temperatures above average in the northwest, generally cooler elsewhere.Thursday 22 FebruaryThe upper low will most likely move further north into the southern tropical interior, however there is some uncertainty associated with the strength and movement of the upper low at this stage. The high to very high chance of showers and storms should shift further north to focus over far northern and tropical Queensland, following the movement of the upper low and trough. A slight to medium chance of showers and storms remains about the northwest and central and southern inland districts. A medium to high chance of showers will be possible along the east coast in a moist, onshore wind flow, possibly further enhanced about the central to southeast coast depending on the movement of a coastal trough over the Coral Sea. However, there is some uncertainty with the evolution of this trough. Temperatures will be cooler than average across most of the state, though remaining above average in the northwest.Friday 23 FebruaryThe movement and development of the upper low remains quite uncertain though it should start to rapidly weaken during the day as an upper trough amplifies over South Australia. The high to very high chance of showers and thunderstorms is expected about the Gulf Country, Peninsula and North Tropical Coast districts near the upper low, with the possibility of locally heavy rainfall with thunderstorms. A high to very high chance of showers and patchy rain areas is also expected about the east coast and adjacent inland as a moist, onshore wind flow persists, with possible isolated storms north of about Gympie. A medium to high chance of showers and thunderstorms elsewhere north of a line from about Camooweal to Hughenden to Gympie, with a slight chance of showers about remaining areas east of about Urandangi to Dirranbandi, increasing to a medium chance across the Southeast Coast district. Temperatures close to average, though daytime temperatures a touch below average over eastern, central and northern inland areas.Saturday 24 FebruaryA new upper trough over South Australia and a surface trough should move into southwestern Queensland and combine with a moist, unstable air mass to generate a slight to medium chance of showers and thunderstorms across much of the state's interior. A medium to high chance of showers is expected along the east coast, increasing to a high to very high chance over the northwest near the upper low and trough. Locally heavy falls are possible in the northwest near the upper low. Note, however, that a great deal of uncertainty persists with the movement and strength of these trough systems.Sunday until TuesdayUncertainty persists with the forecast for this period, though the upper trough over southern Queensland should move northeast into central parts during Sunday and into northern Queensland early next week, ahead of another upper trough that may move into southwest Queensland on Tuesday. Meanwhile, the surface trough should remain over southern Queensland with the slight to medium chance of showers and thunderstorms to its northeast in the moist, unstable air mass. A medium to high chance of showers and thunderstorms in the north and east near the upper trough. The coastal component of the surface trough may move northwards through southeast Queensland and stabilise conditions during Monday and Tuesday, possibly extending fresh to strong winds into Fraser Island Coast waters by Monday evening, and to Capricornia waters on Tuesday.The next routine forecast will be issued at 4:30 am EST Wednesday.Product IDQ10700
