Nah crikey, it’s just to do with the way different models parameterise convection.
Most models produce CAPE and many other parameters as part of their suite of products, including ACCESS-R.

Monday still looks like featuring coastal shower activity starting to spread along the central and northern NSW coast then into parts of coastal SE QLD later or early Tuesday..... before extending further north to the Wide Bay and Capricornia Coast on Tuesday where some moderate falls are possible (aided by an upper trough moving up from NSW).

The more numerous thunderstorm activity on Tuesday looks like it may be a bit inland of the coast as far as SE QLD goes.

I can't see any huge falls for SE QLD itself but some locations near the coastal fringe and islands may see a nice drop as well as those locations which manage to get lucky under a storm or heavier showers.

P.S. ACCESS-G's going to completely replace ACCESS-R (currently scheduled date is December) because it's going to run at the same resolution as R as part of its next upgrade (but since there’s a grace period before all ACCESS-R data is switched off, not all websites may display the new version straight away). So you'll probably notice finer resolution in the ACCESS-G maps in the 3-7 day forecast time period once that happens.

Also worth noting that the current version of ACCESS-R has had a long known tendency for coastal locking i.e. cuts back precip over land by an unrealistical amount at night while maintaining it over the water which results in unrealistically steep gradients in nocturnal precip between land and sea. The decrease in convective precip over land at night does happen to some extent in the real world but ACCESS-R is known for doing it too much. This problem has been completely eliminated in the current version of ACCESS-C.
As a sidenote, the ACCESS-GE ensemble as well as the ACCESS-C ensemble and the next upgrade to ACCESS-C is in the pipeline although I’m not sure if they'll be made public.

Thanks KEN. The nuts and bolts of models is something l know nothing about. So l totally accept what you say.

As l know this is one of your areas of expertise.

What l do look out for being a pattern observer is why GFS CAPE spatial pattern was spot on regarding position of activity, whereas ACC r was off the mark? Most other times it is spot on in positioning generally and so l look for answers.

Matching ACC against stormcast CAPE is something l have never done before and so the investigation begins

So not a big day


The rain totals from the storm burst yesterday. Not a bad spread. Looks like sunshine coast got the better deal

This stalled trough is continuing into Tuesday and Wednesday . So an extension of date perhaps in this thread ?

ACC r is giving west of the divide a good chance or rains and may l suggest possible storms.

It looks as though Brisbane , Gold coast misses out here but activity could migrate east?

What are the other models saying for Tuesday??


The coastal signal runs from Sunshine coast right up to Rockhampton area.

GFS CAPE is usually close to the mark when it comes to typical surface-based thunderstorm areas because of the way CAPE is handled by the model. But there are notable exceptions. For example, it'll often show extreme values off the northwest coast of Australia during the build-up season as well as parts of the tropics even though little to no thunderstorm activity ends up occurring. This is because by default, the CAPE fields displayed on Stormcast is surface based CAPE i.e. CAPE calculated from a parcel that's assumed to rise from the surface and therefore possess the GFS surface forecast temp and dewpoint for that point. In these setups, there's only a very shallow layer of good moisture near the surface which means GFS forecasts those parcels to condense at a low height then cool at the saturated adiabatic lapse rate as it rises further (it stays warmer than the surrounding air and therefore gives rise to unrealistically extreme CAPE values). But on typical hot sunny days, parcels rise from a mixed layer thousands of feet deep in the lower levels so they don't have the same high temp or dewpoint as parcels rising from the surface, and therefore their true CAPE or instability is lower.
Conversely, GFS surface based CAPE often tends to show very low or even non-existent values for dry inland storms even though it results in lots of lightning - this is because convection is helped by a layer of moisture aloft rather than the surface where the surface based CAPE values represent.

This is why there's different types of CAPE that are looked at by forecasters such as mixed layer CAPE in the lowest X hpa of the atmosphere, most unstable (MU) CAPE which uses parcels rising from a level that yields the most CAPE, effective layer CAPE which uses parcels rising from a level where parcels are likely to start rising freely on their own from, etc.

Above is the ACCESS-R CAPE for 4pm yesterday based on its 00z run. I'm allowed to post this particular version. And the preceding image is the detected lightning within the 24hrs after 8am Saturday.
As you can see, the general area is reasonably well represented by the storms that ended up occurring although note the low values inland which is typical of inland low-rainfall storms because convection is encouraged by moisture aloft.

Yeah, I had a detailed look at ACCESS-R, etc soundings for various points around the region. Below is a summary of what I said elsewhere:

" There's definitely more than enough directional and speed shear (caused by the freshening ESE onshore low level flow after the small weak near-coastal low drifts away and weakens, undercutting the strong westerlies above) to support severe storms.
But instability is very modest in most of SE QLD so I think it'll be a case of "only a slight chance but if anything got tall enough, it'd tap into the shear and potentially become severe". "If" being the operative word.

Both EC lightning and ACCESS-R soundings look somewhat more favourable in northern areas such as the Wide Bay and Burnett, and some western parts of SE QLD but it could conceivably go either way.
ACCESS-C tries to develop some convection around the Scenic Rim ranges which then drifts in a rough NNW direction later as it grows somewhat. Will be a wait and see situation with today.
Overall though, today looks far from epic to me. "

I'm actually not too hopeful for anything more than localised storms for SE QLD goes to be honest.

But regardless, shower activity should start increasing from later tonight into tomorrow in the region.
