Good morning early birds! Certainly, a vast variety of weather across the country at the moment as we have a high amplitude pattern in progress. Nice band of storms through the west overnight and further rain about today with squally winds. Will that rain finally break the dry deadlock over in SA?
A warm end to the month for many areas but does it hang on into Winter or is that polar blast still on the cards?
And the jet stream, playing havoc with modelling, will that become a feature to have an impact on our nation into the medium term with higher chances of above average rainfall spreading from west to east over the interior or even get involved in cold fronts moving over Southern Australia?
Lots to discuss today and throughout the week but here is the short-term features.
The simulated satellite shows the moisture and movement of weather quite nicely so lets see what is happening.
Monday, we know we have the system over the SWLD bringing gales, showery weather and a colder shift to some parts of the coast from where the temperatures were previously. We also note the east is relatively damp with onshore winds. A high though over the southeast keeping things as they have been most elsewhere for today and tomorrow, but can the front over SA bring rain into Ag SA tomorrow and Wednesday
The remains of the system over in WA collapses over in the southeast and east, but as I keep referring to the high in the Tasman, it is the driving force as to how much inclement weather is observed in the east. But you can see patchy rainfall and thunder moving into southern QLD, NSW and VIC, clearing SA during Wednesday with drier weather back west and north.
This is where it does become really interesting. The moisture left over the from the WA system could be drawn into a developing low offshore southeast QLD and this could whip up a showery spell for parts of the extreme coastal areas in the east. The weather soupy but mostly fine over the southeast on Friday but look at the next cloud band being drawn in once again ahead of cold fronts rushing through the Southern Ocean. So, by Friday we may be staring down at a more interesting weather feature to finish the month of May across the country.
This is now Sunday, and you can see that surge of colder air rushing northwards through the Bight towards the moisture in feed rushing through the jet stream, but does it combine? Do we see the polar jet and the subtropical jet become one or repel each other? This will determine rainfall spread as we go into next weekend and the first week of June. Note over in NZ, what happens when it all comes together!
End of May, cloud band remains a feature over the nation with rainfall spreading through interior parts and showery weather for the southeast with a blustery westerly flow and colder air surging north. Showery over southwest WA too with another front with temperatures coming way down for many.
So quite a few systems on the board that I will be looking at further in the weather video update from 8am EST.
