An assessment of the weather
I have posted a few times about recent weather. "Hot windy and dry" is a concise summary. The official forecast for the rest of this week appears to suggest that the 'dry' component is about to change.
However I get a feeling that the broad weather pattern is in a transition phase and thus forecasting is a bit tough, so the promised showers may not occur. The clouds did look promising for a while in the evening of the 21st ...
... but generated nothing wet.
There are another couple of forecasting services around. I suspect this one from Elders ...
... is a different analysis of the same data as used by BoM. However the Weather Channel probably uses different data.
At least I hope they do to come up with such a different forecast!
The following table summarises the synoptic words for the three forecasts as at 1700 on 21 January, with those I regard as equal marked in yellow. I'll update the table as time goes by, highlighting the forecast I rate as closest by setting the text to bold red.
In effect anything - other than snow - is possible!
By 4:30 on 22 January the picture has changed as far as BoM are concerned.
I think we are back waiting for a storm named Godot! It is possibly indicative that on the evening of 23 January the ABC TV News presenter commented about the difference a day makes in weather forecasting.
The numbers are in. TWC was pretty much on the money while BoM were miles off.
