Interesting 48-72 hours ahead for SA as a low is set to move through Late Monday/Early Tuesday morning.

Hot North to Northeasterly winds will filter into the state due to a surface trough dragging in heat with temps exceed 40 with some places pegged at 45-46 in the far north but may struggle for Adelaide giving the cloud cover to form ahead of the low otherwise clear skies would easily be 42-45 for the Adelaide area.


Superior shear with this with a good LLJ averaging 85-110km/h with good powerful shear in the mids and uppers almost clocking 280 at 300hpa so will help with lifting of parcels.


Timing:
EC favours the best of the activity in the early hours of the morning around 430-500AM for storms while GFS favours late Monday night into Early Tuesday Morning.


Rainfall:
Not too much is expected for Adelaide with maybe 2-5mm at most, more general falls of 5-10mm out west with iso of 10-20mm under thunderstorms but dries rapidly east of the ranges.

See how we go but hopefully we do get a decent early weather Christmas Present from the weather.

A little bit of rain here - barely enough to wet the rain gauge me thinks though...

Yer unsure about that, I'd still think there is a chance of an evening thundery shower or two, more likely over EP and YP sliding down however. Shear is very good, lift is excellent, but heat is now tempered a bit by this large cloudband from decayed cells that models haven't handled all that well. New storms should erupt over the west this arvo and filter SSE along a slow moving band along a cold front, elevated in nature.

Best chance for the Adelaide area is prob after sunset till 3-4am when things prob move east of us. Nocturnal cooling may play a part tonight so see how it goes. Not a world beating system as I am worried about upper cluter and gunk just warming the 20-25,000ft levels but should be something to see before it begins to favour more rainband later into the night.

TS cool

I'm excited for a temperature change...and rainfall. Both of those in combination would be great! What I don't want to hear is more about fire weather!

16.4mm Seaford Meadows....a lovely drop but sadly as expected the rainband took over as things got near Adelaide. Very frustrating given how strong it was firing out west but the timing was just a bit too late for maximum potential. A few very nice crawlers seen however... But very glad for the rain at least.

TS cool

That was nice. The kids woke me up middle of last night so I got to watch a nice light show.

Saw a few Ripper Rita crawlers around 845pm while near West Beach. Heard rain and a rumble sometime during the night and found 9.4mm in the gauge in the morning. Nice drop for the garden but most importantly some cool air to reduce the temperature in the house and be able to sleep!
