Synopsis and some thoughts smile :
Written: 1st of March, 2019; checked and edited 3rd, 8.15 pm ACDT -- all dates from the 1st

With the beginning of March (and Autumn 2019) smile ... prevailing weather dynamics look a little closer to a gathering of upper-trough-related features in the Bight, for about the next 4-5 days [within 7], or so smile . Higher dew-points at or above 10 C may occur between late tomorrow [Saturday, 2nd] and Tuesday-Wednesday [5th-6th] higher dew-points confirmed start Kuitpo AWS last 24 36 hours, Kent Town, similar. Maximum temperatures falling to 25-30 C, possible barely 20 by the 6th; minimum temperature remaining above about 10.

MSLP indicates a period of relative stability with figures 1010-20 hPa may grade higher, towards 1020 hPa, in the coming week [ending about the 7th]. A reasonably strong middle-to-upper-level ridge seems likely to navigate its way from about Central WA, E-ESE towards South Australia; winds behind this feature at 500-hPa being much stronger NW-to-SE [associated with increased westerly-belt activity]. This [NW-to-SE] axis running across SW-WA clearly evident last 12 24 hours, moving progressively east.

As this milder upper feature moves E-ESE, into the Central-Upper Bight, it can temporarily block a NE movement of the Deep-SW Upper-Trough system, from below Perth WA. The middle-to-upper-level ridge can also enable westerly winds to the south of it to form a more zonal pattern [in the South-Central Bight]. The formation of this zonal pattern / wave in this region would (a) be broader than past, milder upper-trough features [to glance Central SA, since about 20th to 22nd of December 2018, Bureau Observations. More ESE winds prevailing, Kent Town, SE, Kuitpo], and (b) provide impetus momentum for a more vigorous system to reach Central and SE-SA shores [by the middle of the week ending 7th].

Streamflow response thought to be mild at most.

Disclaimer: as previous.

Seems a slight-to-modest chance of precipitation starting around the last week of March, for the SA Central District smile .

Edit: Also a moderately high chance of flood / flash-flooding near / around Weipa QLD, in the next 3 days.

Streamflow readings showing minor and moderate levels along the Daintree River shocked -- and steadying, north of Cairns QLD, following falls of 100-200+ mm in the last 24-34 hours.

There have been very big streamflows in USA in the recent week due to combined rainfall and snowmelt, at it's most extreme it caused failure of a 90 year old hydropower dam known as Spencer Dam . A big mess in Nebraska. Fortunately no known loss of life and probably why it did not make much penetration in recent media.

Meanwhile in Australia, the areas of south east QLD, Northern NSW, Wide Bay Burnett etc on east coast have got rainfall producing close to minor flood levels. And TC Trevor crossing Cape York delivered a max of 300 mm in 24 hours to 9am today at Lockhart River but generally totals were around 100-200m.

Streamflow events beyond Australia have always taken a backseat, from my perspective, to events occurring within the our Region...so while it might be a passing curiosity from a statistical point of view or similar, I do not see them as newsworthy. Mention them yes, but they do not affect us in direct weather terms. Regarding the rainfall of the Lockhart River Region, that would be newsworthy, however as this thread is not dedicated to each specific streamflow event nationally, my tendency, objectively, is see them from a overall perspective, relate to average annual rainfall...thus if an event's magnitude is a one-off type or unseasonal, that would render it notable, or more. However if a certain type of run-off causing rainfall system is a common in a given region...then that applies as well.

Granted people may prefer a more popular approach and less science, as this is not a science forum...in that light to be taken with a grain of salt...however objectivity, in a fundamental sense, is not something that can be easily dismissed out of hand, or by an expression of views devoid of links...so there is some sort of necessity for balance between those two in the longer term. Being reasonable is a start!

Potentially 80 percent chance of any rain tomorrow (for the Adelaide Hills) with 2 to 5 mm across the Central District areas smile . May even be accompanied -- with a prelude -- by a rough NW-direction tropical in-feed, somewhat remaining from cyclonic activity along the NW-WA coast.

Hopefully a chance of a significant frontal passage across the Bight around the Easter Long Weekend (19th to 22nd of April). The [500 1000 mb] thickness approaching 540 dm, the 850-mb temperature, near-zero. The barometric pressure pattern starting to resemble the higher variability of winter-like dynamics.

There is highly likely to be a change in the weather pattern for SE Australia around Saturday into Sunday (20th-21st April), regardless of whether significant rain falls or not...[rain] still needed though frown .

Maybe a greater chance of observable, measurable precipitation within the next week across SE Australia smile .
