    It’s not a bad look for the 26th-29th period.


    But it probably marks the end of this round of precipitation and “interesting weather”.

    The MJO is leaving the region over the next week or so.
    And the AAO is looking like it will go negative again, which during summer means lots of ridging over Australia and drier conditions. Not sure how long it will continue, but it’s going to be a key indicator in terms of when we will see more interesting weather in the long long term.

    There's been quite a bit of rainfall in NW WA and the central parts of the country in the past 2-3 weeks (although some places have missed out) and more extensive cloud cover than in the previous months (that lead to the really hot temperatures building up) so that should limit the amount of very hot air in the interior of the country, which might give us some respite from very hot temperatures in the SE. I dont see the monsoon trough moving too much though, so I dont know if the 'interesting' weather will leave us should the MJO move away and the AAO go negative.

    Yeah I don’t think we will go back to very hot conditions quickly, but IMO less precipitation gradually. Probably not to the same dry levels as before. There obviously has been a sensible weather “pattern change”, and it’s likely to be cooler for us for the next two-three weeks. Monsoon will be there, so yes there will be more to tap into than say there was a month ago, but it won’t be the same as having the MJO in town.

    Will likely scale back but for now it's remaining staunch.
    Cracking little system this one, for summer:

    Negative titled trough pushing through the Bight on Tuesday suggests to me we're likely to be in for some 'shear-based' severe WX Monday to Wednesday, IMO.
    At least through the SE of the continent.

    Could be a box full of sharp objects for Tasmania, but looks OK for Southern Vic.

    Lucky it 'aint winter, this would be a 30-50cm system, mid-August.

    Certainly different flavour to the rainfall we have seen over the past week, but nonetheless appreciated.

    EC has a dusting for the Cradle Mountain area on the charts.

    Certainly has a decent cold pool associated with it, for summer.

    Levi's Tropical Tidbits website is down.
    3rd-4th time this month.
    Sounds like he's having server issues. Bugger.

    Going to be some serious winds whipping through the 40's and 50's over the next week.

    Thanks to a massive global flux of momentum, via the strong MJO signal through to the extratropics.

    Perhaps time to pay the Canadian model more attention this season:

    The Canadians are withholding the Canuck upgrade over the Middle East Region until Iran pay up...

    I’ve been riding my bike in the Monaro recently. In winter, there are certain places on roads where snow always accumulates and hangs around for a while. Usually where there is a fence perpendicular to the prevailing wind and a gully or ditch beside the road. The fence acts as a snow fence, and the snow drops into the gully. What I’ve noticed this week in a lot of those places is exactly the same phenomenon, but drifts of dust accumulating instead of snow:eek: Looks exactly the same, but different. Sad sign of how dry everything is:( Here is an example

    Not to keen on the next node Friday/Saturday.

    Last Thursday was really bad here on the NSW South Coast. This chart looks to be a big threat.

    Is that between Cootralantra and Buckenderra/Braemar Bay? Those hills look very familiar. Quite the snow country down that way in winter, with excellent SW exposure and plentiful non-NP land of 1,300+ m.

    Back in October 2019...ten-fold greener! Berridale was still very parched then, as usual.

    Any views on fire weather next weekend? Not hearing much talk but looks like something to keep an eye on to me.

    Very warm days inland, westerly/north westerly winds by day for much of the week with strongest winds and hottest temps next Friday through Saturday sometime. Having a guernsey at Sentinel Hotspots and RFS burn areas Adaminaby complex has potential to make a run towards Cooma from Yaouk area and the east of Bombala fire is lined up a bit to well across unburnt country towards Eden. Hopefully winds stay down and any fires don't move to hard and fast.

    A few cms of snow is forecast for the Tasmanian mountains on the 3rd of February:


    Thanks to a decent deep cold node passing to the south of Tasmania.

    Keeping an eye on alpine temps tomorrow. The 30C forecast for Perisher would be an all time record I believe.

    Yeh hot the next two days in snowy and surrounds. Current record high for Cooma is 39.5C from memory. Next two days forecast 39C so could give it a nudge too.

    Forecast to hit 34° C here today, so it could give my Jan 2019 reading a run for its money.

    Right you are. Which beat something like 29.6C a couple of years earlier (which is what I had in mind)

    Lots of the BOM climate stats entries are out of date. my My guess is they just don't have the funding to do the work properly anymore, and focus on what's critical in the short term.

    It’s 2020.
    If the BoM doesn’t have a data management process for an AWS then it’s ‘mismanagement’, not ‘funding’.
    Data verification is the only ‘reasonable’ variable inhibiting the update IMO.

    Maxed-out at 36.1° C yesterday (1,265 m AMSL)—my highest reading on record!

    Cabramurra 34.0° C; 32.4° C previously.

    Many stations around the Monaro and Snowies appear to have set new high minimums and Canberra. Cooma airport min 26.5C and went to 39.1C yesterday beating previous record of 38.2C from last summer. Cooma Visitors centre at 150m lower than airport site has current max record of 39.5C so assuming the visitors centre is a bit warmer, maybe 1C as you'd expect and it's a chance of topping 40C. Be interesting to see what verifies. Definitely a unique weekend for the Monaro combining persistent high temps over many hours and prospect of severe fires coming out onto northern Monaro today.

    Not sure we got under 30 last night if so it would be a record here. So humid. Evap coolers don’t work in these conditions we had it going full bore all night and it was still 30 degs in the house this morning.

    Cooma AP was 23.9 yesterday at the 9 am reset so that will go down as the minimum.

    This morning it was 31.9 at 9 am so tomorrow morning could give the record a shake.

    Lot of weather stations. A lot of data that needs to be checked - but I rarely if ever see a change in max/min record stats in recent years. I think it comes down to fundable priorities. I might even send them an email for a news article and see what they say.

    Yeah, hard to work out why it wouldn’t get updated and a lot of contradiction in those historical summaries.
    Should at least be * if it’s not valid or not yet updated/verified etc!

    Yes, it looks like pretty much the entire eastern part of the country will be getting significant rain, on top of the northern monsoon and cyclone rainfall in Western Australia
