Early October weather

A few uimages etc which I need to publish to link to.

On 14/10 the Weatherzone radar looks promising.

Unfortunately that came to nothing - if 1.8mm fits into your definition of nothing!

For the weekend of 20th-21st the BoM and Weatherzone both promised great things.

If we get the median amounts (15 and 8mm) that would be very good.  If we get the amounts that are 25% likely (25 and 20mm) it would be brilliant.  That would be especially good if it came with some lightning to drop a bit of nitrate fertiliser on the lawn!

The Weatherzone radar doesn't look too promising early on the 20th!  The system seems to be slipping to the SE!

For an alternative view I looked at the BoM Satellite imagery (note that is a real-time site so will not look the same when you look at it) and that was more promising.

It was in fact very pleasing that there was no rain around 10:30 to 1130 as that gone the drone videoing out of the way in sunny weather.   This was the situation at 1130

 And here we go at 12:15.  That magenta colour means serious rain!

 There was also a lot of thunder and lightning, so we should have got a lot of free nitrogenous fertiliser.  This image was from lightningmaps.org.

 It bucketed down ...

 .. and we scored 12.6mm in not very long.  At its peak my weather station recorded a rate of 180mm per hour, which is the third highest rate I have recorded.

The Creek is no longer dry.  I think it might have gone over the road, but not seriously so.

 By 1420 the first lot had gone, but a second serve was brewing.

There were odd spits amounting to 1mm during the afternoon but the next real storm didn't hit until just after 4pm.

While not up to the morning's effort, the rain rate was 96mm per hour: this is the 29th (out of 1994 records) highest rate recorded.  By the end of that we were up to 18.4mm for the day.

Having got that rain event out of the way I looked at how temperatures in October (so far) compared with the average since 2010. The overall average temperature for the first 22 days was slightly less than the long term average for that range of dates.  I found that surprising.

Perhaps I shouldn't have been surprised.  We had a couple of spells of maxima being well below average for that date almost being balanced by a slightly longer period in which minima were well above average.

The 27th of the month is hardly 'early' October but it is earlier than my full report on the weather.  I thought these lenticular clouds over the escarpment were rather amusing.
