A very hot and steamy night in most places in the metropolitan area. As a result of the high dew points it caused the feel like or apparent temperatures not to fall below 27°C all night.

Today ( Friday) will see the same weather pattern of showers and possible storms once again. Below are just a few of the GFS, ECMFW and Meteye take on the days possible forecasts. The atmosphere is pretty primed so we could see those showers from later this morning and storms may start brewing according to the stormcast models early afternoon or into the evening.

What a hot humid night. Actual temperature through out the night was 25.8°C, dew point was 25.8°C and the apparent or feels like temperature was 31.5°C. Heavy rain hit around 01:00 am and we had a total at Lawnton of 21 mm.

Yesterday there were pockets of showers and storms albeit very slow moving. I think this was one of a few reasons we didn’t see the day pan out as the models indicated, the steering winds were not strong at all, so the cells that developed stalled. It has been tricky lately trying to get things smack on. The models are underperforming and even BoM are updating forecast at all times of the day. And there are a few reasons for this too. The atmosphere is so primed and dynamic that just the slightest change effects the whole set up. Plus the monsoonal weather up in the North and the Lows are having an impact on our weather.

The Coral Sea low is not expected to form into a cyclone until Monday now. That keeps moving around and is keeping models and forecasters guessing the next move.

Today for the South East and NE NSW it is much the same as the last couple of days. Showers with possible storms and some could be heavy falls once again if you happen to be under one. Going by the GFS model below and Sounding it is very Coastal and not a lot of rain nor steering/ shear through the 700-500 mb.. So it could be hit and miss, or things could rapidly change. So please just keep an eye to the sky and listen and watch for any warnings if things change.

Just after I post, BoM have updated their STW,. Unfortunately a little late but at least they have taken action.

A very hot and humid day. The chance of any storms seem to be heading North into the Low that is in the Coral Sea. Below is just a simple way of looking at the setups of the weather using just the Lifted Index charts.

Technical data available for the system

IDQ20065
Australian Bureau of Meteorology
Tropical Cyclone Warning Centre

TROPICAL CYCLONE INFORMATION BULLETIN
Issued at 10:54 am EST on Sunday 21 January 2024

At 10 am AEST Sunday, a Tropical Low with central pressure 998 hPa was located
over the Coral sea
near latitude 15.0 south longitude 154.4 east, which is about 495 km east
northeast of Willis Island and 940 km east northeast of Townsville.

The low is slow moving and should gradually intensify over the next 24 hours.

Tropical Low 05U is developing in the Coral Sea and is forecast to track
towards the Queensland coast. A coastal crossing is likely around the middle of
the week, with the most likely zone being between about Cairns and Mackay. A
severe coastal impact is possible, particularly if the system crosses near or
south of Townsville.

The next Information Bulletin will be issued by 5 pm AEST today.

One little nasty cell with heavy rain just South of the SEQ border. I don’t think BoM have looked at it. But anyway see what happens.

Just having a look at the 512K Willis Island Radar and the low is still heading in a NNE direction. As per the doppler radar you can see the main system is moving away from the radar, that is North of the radar.
This is in line with 10:00am- 10:00pm 21 /01/24 track path.

A Hot and Humid day install for much of Queensland. The Dew points are making the atmosphere feel so oppressive. With temperatures in the mid to high 30’s predicted, the high dew points will make the feel like temperature closer to 40°C plus. There is a very small/slim chance of a tiny band of storms just around the Coastal areas on the border up to Brisbane. But the forecast sounding has a massive dry slot in the lower levels then increase to drier air above. So we could see some towers go up, maybe a dry cell or virga with a rumble or two, but it is a slim chance.

As for the Low 05U not a lot has changed at this stage. It is very slow moving but should start to move a little to the West. The models are sort of coming into a alignment in small variations but it is still a long way out in the life of a Tropical Low/Cyclone.

The latest Meteye has the Tropical storm moving inland still and moving a little further south with a recurve towards the coast. But once again we are a long way out. The best way to describe this scenario comes down to Lorenzo’s chaos theory that he discovered while running a weather model in the 1950’s. It became better known as the butterfly effect. The small changes added together can make a bigger change to a storm system such as 05U.

So at this stage stay cool and here is the latest Meteye run from BoM.

Just saw an update and there has been a slight movement to the North with the possible crossing of the Coast. This is where the models will jump around so much. Those tiny butterfly effects. But it is just worth keeping an archive of the movement in the models for future references.
This all could change in the next few hours. The other scenario is it could burn it self out by using a lot of the warm water it is sitting over. So many variables to consider. Time will tell us what is happening.

Posted this Meteye stormcast this morning.

IMG_3559.jpeg

This is the latest and you can see the crossing is closer to Townsville at this point in time.
Be interesting to see where it does eventually cross and if it does cross is another scenario. So many variables as I said before. The main thing is to prepare for the worse and hope for the best. That is all we can do. Keep an eye and ear to all the advice/warnings from BoM and reliable media sources. Some FB pages have a doomsday scenario and we know better than BoM attitude, so please choose wisely and stay calm and have a plan of action.

A very hot and humid day for the area of this thread. But hopefully we will feel the effects of the Southeasterly change that is currently moving through.

The latest Advisory update 3 for Possible Cyclone. The only reason I say possible is due to the lack of structure at this very point in time. Still quite messy on the Satellite Imagery. But this could change over the next 12-24 hours.

TROPICAL CYCLONE ADVICE NUMBER 3
Issued at 4:44 pm EST on Monday 22 January 2024
Headline:
Tropical cyclone impact likely on the Queensland coast from Wednesday.

Areas Affected:
Warning Zone
None.

Watch Zone
Cairns to St Lawrence (not including Cairns), including Townsville, Mackay and the Whitsunday Islands .

Cancelled Zone
None.

Details of Tropical Low at 4:00 pm AEST [3:30 pm ACST]:
Intensity: Tropical Low, sustained winds near the centre of 55 kilometres per hour with wind gusts to 85 kilometres per hour.

Location: within 55 kilometres of 15.6 degrees South 153.9 degrees East, estimated to be 860 kilometres east northeast of Townsville and 425 kilometres east of Willis Island.

Movement: slow moving.

A tropical low (05U) is slow moving in the central Coral Sea and is likely to become a tropical cyclone during late Tuesday. This system is forecast to track southwest over the next few days towards the Queensland coast as it intensifies.

The system is forecast to cross the coast, most likely on Thursday between Innisfail and Airlie Beach. From Friday, the system is forecast to move inland and then further south.

That slim chance of a storm did come together. GFS had a very small area and isolated chance of a storm East of the Ranges.

A little bit of a reprieve from the hot weather. If you can get into the breeze is quite comfortable, but once you are out of it, hot and humid but nowhere near the last few days.
Most of the action right now is with the Tropical low 05U and a thread has been started for it at

More warm/ hot cloudy days. The expected rain has stalled due to the Tropical Lows for slow movement.
So Saturday, Sunday and Monday are shaping up to be the wet days at this point in time. Not a lot of rain is expected. But just have to see the impact, if any, this low has on us.
Just using the LIi charts to show the low is dragging any wet weather or storms to the North.

This afternoon the Tropical Low up North has now officially been named Tropical Cyclone Kirrily.

TOP PRIORITY FOR IMMEDIATE BROADCAST
TROPICAL CYCLONE ADVICE NUMBER 15
Issued at 4:49 pm EST on Wednesday 24 January 2024
Headline:
Impacts from Tropical Cyclone Kirrily likely to begin for coastal and island communities tonight and Thursday morning.

Areas Affected:
Warning Zone
Cardwell to Sarina, including Townsville, Mackay, Bowen, the Whitsunday Islands, and extending inland to Charters Towers.

Watch Zone
Innisfail to Cardwell.

Cancelled Zone
None.

Details of Tropical Cyclone Kirrily at 4:00 pm AEST:
Intensity: Category 1, sustained winds near the centre of 75 kilometres per hour with wind gusts to 100 kilometres per hour.

Location: within 55 kilometres of 17.4 degrees South 152.4 degrees East, estimated to be 630 kilometres east northeast of Townsville and 530 kilometres northeast of Mackay.

Movement: slow moving.

Tropical Cyclone Kirrily has developed in the central Coral Sea, and is expected to continue strengthening as it tracks west southwest towards the Queensland coast. The system is likely to cross the Queensland coast Thursday night between Cardwell and Bowen as a Category 2 system.

In the longer term, the system is likely to track further inland as a tropical low, bringing heavy to intense rain to parts of the northern interior and western Queensland.
