Issued 19th August 2018. FINALLY some hope! After a very long period of no rain through July and August many computer models are indicating some rain and storms across large parts of drought affected QLD and NSW later this week. Further forecast updates will be required and issued during the week as changes occur. Above image: Rainfall forecast totals (SUBJECT TO CHANGE) via Windy.com
For the past several days leading global models have been consistently forecast a significant cold cored Low pressure system to move North East across South Australia on Thursday and into South Western QLD and Western NSW on Friday. The exact final track will be critical for some of the area rainfall outcomes during Friday, Saturday and Sunday.
Widespread 15 to 25mm rainfall totals are possible at this stage from Rockhampton South and East of Charleville in QLD, North of the ACT and East of Cobar in NSW. Areas further West in South West QLD, Western NSW, Southern NSW and the ACT may also see some thunderstorm and rain activity though falls are expected to remain lighter.
Initially isolated storms could develop through Western NSW on Thursday afternoon before pushing further East into the Eastern half of NSW on Friday and Saturday. Scattered showers and patchy rain areas are also possible.
Showers and storm activity is expected to develop through the South East quarter of QLD on Friday before continuing on Saturday. On Sunday all activity is forecast to shift further East to influence the Central and South East Coast of QLD, Northern Central and Southern coasts on NSW though there remains a fair bit of uncertainty for Sunday.
It is something which is better than absolutely nothing. It may save a few Winter crops and it may be to late for others. What we do hope is that many people across drought affected areas get some liquid gold so fingers crossed. Highly detailed and accurate 24 hour rainfall and thunderstorm risk maps will be issued over the next few days to cover the system on our premium members weather service.
