Another warm and humid night. Unfortunately today brings the possibility of more isolated storms with some possibly being severe. The main areas at this early stage is the south east and border ranges of NE NSW and SEQ and the southern interior.

IMG_3454.jpeg

As the forecast sounding indicates at this point, there steering winds are quite weak and so the main threat will be slow moving storms and heavy rain.

Please stay safe and listen or watch for any warnings throughout the day. We could expect to see heavy showers/storms from late morning onwards.

Showers are starting to build up around the areas that the models were forecasting for heavy showers/storm. Other areas maybe be in firing line so please just keep an eye on any warnings that are issued.

The Brisbane airport sounding. It highlights that there is a lot of moisture in the atmosphere, the lack of steering winds or shear hence the possibility for slow moving storms. A fair bit of instability with no cap, so storms wont take much to fire off and the TTs indicate that they will be isolated ( not a widespread storm system) .The main area of concern once again would be for heavy falls.

A few little cells popping up throughout SEQ and inland. A few rumbles with some of the small cells. But most of the action at this stage is over the boarder. Below is the radar image ( 512K Mt Stapylton)

Nice line of showers coming in off the bay right now. BoM have stated about 1 mm of rain at a 40% chance. (Just had a quick glance then) So we have had our 1mm plus at 100% now.😁😁, just kidding I definitely know how the forecast works with the percentages but definitely have got more than 1 mm. Very nice as there is a bit of a cooler breeze along with the showers.

The weather for Friday for the area within this thread is for showers and average temperatures. On Saturday we may see Storms once again, but at this stage it is forecasting for Coastal activity rather than a larger broad area. But it is something to check with the next runs.

Most of the action today will be North from Mackay to the Cape. The members in the Far North Queensland thread will probably no doubt be following closely the monsoonal activity that is starting to form up through that area.

Below is the satellite imagery for the North .

And the 4 day outlook.

Saturday 13. High chance of widespread thundery showers from around mid morning. A top of 30°C should make things feel a little humid and fuel the shower/ cells for storms to pop up. GFS wasn’t really interested in the idea. So Access and EC was unto the possibility of this occurring. But like yesterday, most of the action will be Far North Queensland from Mackay to the Top End.

Stay safe and have a great weekend. Still looking through the modelling.

Just showers, hot and windy at times for much of the Coastal areas East of the Range.
Below is the probability of showers .

IMG_3483.jpeg

And below you can see the lack of storm potential, not to say it is 100% definite as we could get a thundery shower in he mix. The models have not been right on the money lately to be honest.

Monday, isolated to widespread showers along with possible, ( no definite,) thundery showers/ storm for the Southeast and NE NSW. Below is the GFS and EC stormcast. Once agin the models are not picking up the Southeast area to well but is doing a good job with the monsoonal low and heavy rain up North. At this stage it looks like we are in a holding pattern of warm temperatures and showers.

Just running through todays updated models and they are now showing a little more activity that when I 1st started looking at them last night and early this morning. They were a little underdone or light on with the showers/rain and storms. 1 st rounds of thunder and showers started about 9:45 am around the Strathpine area where I was this morning. But to he honest it was such a nice treat it didn’t matter. Tomorrow ( Tuesday ) could be the same. They were deep rumbles overhead which was pleasant to hear.
Still most of the activity has been up North of Mackay. The members in the Far North Queensland are onto it.

Some interesting long range forecast being thrown around by the different modelling systems for SEQLD. It is still a long way out so things can change but worth keeping an eye on the models and see how they fair.
These are all for the same timeframe of January 24, except for the ECMWF which only has run till the 20 January.

GFS Model is the most aggressive

IMG_3492.jpeg

CMC has the same low but further to the East.

IMG_3493.jpeg

NAVGEM

IMG_3497.jpeg

ECMFW, run stops at January 20.

IMG_3494.jpeg

As I said before, it is still a long way out and things can change with each run of the models. But worth keeping an eye on them just in case.

Much the same weather for Tuesday, Showers and maybe thundery showers/storms.

With regards to the models hinting at a low/cyclone hitting down in the South East, models have already started to shift their forecast. But as they are very unpredictable it s worth just watching. BoM have come onboard and are watching tropical low 05U. (Technically not until Wednesday)

Tropical Low 05U
Coral Sea tropical low developing this week
A tropical low is expected to develop in the Coral Sea this week and initially move east, away from the Queensland coast.
It will likely strengthen on the weekend and could start moving back towards the southwest.
It is expected to remain offshore for the next seven days with no direct impacts to the Queensland coast.

Wednesday is a bit of a pause rewind and repeat of the same weather, showers, hopefully not as heavy as it was down the Gold Coast yesterday. Thundery showers/ possible storm Forecast have been a bit off to be honest. Some of the forecast shower/ rain totals have been way above those predicted. But to be honest and fair on BoM, the atmosphere is so saturated that it is hard to know with certainty how much will fall and where. Most times it may only be an hour or 2 before the event or in real time.

As for O5U, the Coral Sea Low, it is worth keeping an eye on the BoM’s cyclone update.
Some of the models are still finishing their runs so are not ready for posting. But ECMFW has now thrown this into the framework. Not saying this is what will happen because Cyclones and Severe weather events can change so rapidly. So do not panic. We are still a long way off in terms of Cyclone forecasting. When you stop and think of all the cyclones, how many have been forecast to cross the coast only for them to suddenly loose strength and steer to the East away from the coast.

This is ECMWF ensemble for a possible forecast.

IMG_3505.jpeg

As I said do not panic because this may chop and change so many times.

Storms have been making their way across the Southeast this afternoon.
Storms should reach the bay and move out to sea as the afternoon moves on.

A pretty nasty signature on the doppler radar near Darlington. A very dark ( high winds) V notch.
BoM seem to be dropping the ball. Storms are over us and heading out to the Bay.
Below the V notch on doppler, radar and lightning tracker.

I see you over here on your own :)

Good old QLD is firing on both ends tonight. Love a good old school wet season.
If this cyclone runs down the coast you could see some good flooding with the catchments already full and flowing from a nice summer of storms.



Cheers

BoM have finally looked at the radar,sorry for sounding negative but I just don’t know what is happening internally. No regional manned stations anymore.

It is a bit lonely, but hoping some of the members may come back and join in. BigGrin

It really has been an unbelievable wet and storm season for Queensland, in fact the whole of Australia, and still more on the cards. Definitely the most out of whack El Niño I can recall.
