Hi all. It has been a long time since I have posted here cheers

After another rather sticky day (dew point hit 19C around lunchtime) following on from what seemed to me to be an unusually humid summer it has got me thinking. How would last summer compare in terms of dew point and humidity to the long term averages? I personally don't recall so many occurrences of high dp's in one summer but I'm basing that on my unreliable memory wink Having said that, I have found the humidity come up in conversation with people quite a bit in recent months.

I guess my question is has it really been unusually humid based on historical averages and if so by how much? Is there an easy way to find out?

Cheers,

Ev

hi chris,
yer your right, been there done that, as have many others.
in the days before i had internet,(pre 1994), it was a hit
and miss affair, when there was real hardcore potential i
used to call the bom for updates. back then i was a closet
chaser, i didn't tell anyone for fear they thought i was
loony, even i thought what i was doing was weird and probably
the only person in australia.
then came pay tv, discovery channel and american stormchasers,
thats when i 'came out' and a friend coined the nik
ThD Ht, i used WZ for a long time before i clicked on the
forum button to see what was there, the rest is history.
definitely been an interesting journey.........

Ah the good ol layout, had only a few years of actually understanding what the colours mean until they upgraded the network Aus wide.

IMO they should have an AWS near the radar site like some others have. Otherwise I'll plonk one there myself poke

models pushing next system too far north and east.
Most of sth agricultural areas and coasts not likely to see as much as expected now. 5-15mm.
Nth agric areas much better and could still see 20-50mm.

thanks for that vinnie,
it's a good and interesting read and excellent analysis and
summary of the december event, being a significant stand
alone event in itself it only forms part of a much bigger
picture overall, as pooraka states the real anomoly was in
the cluster of events over the approx. 5 week duration from
christmas to the end of january.
one - three such anomalys per summer with late spring and
early autmn included to me is quite acceptable and normal.
in all my years of weather watching this was one out of the
box but having said that pre 1990 i've forgotten more
significant stuff than remembered. one event of note i
remember occcurred at naracoorte in the late 70s where 72
hours of non stop thunderstorms day and night occurred,
there was very little movement of anything but time has
blurred specific details. it was certainly significant
enough for me to lock it into a perminantly accessible
memory archive even back then in the early days.
2 things i've discovered with stormchasing.....
1) when something significant is happening enjoy it because
you will never see it again and
2) dont worry because there will always be something just
as good or better lurking just around the corner waiting
to bite you on the ass when your not looking.

roxby downs doing good since midnight, under the influence
of an upper low and coldpool seems to be currently located
about 90km WSWbyW. up to 16.8mm so far, might crack 20 if
they're lucky, prolly a bit of a slush pit up there atm.
interesting that woomera 80km to the south has only 0.6mm.

29mm at Tarcoola as well, most of it within 90 mins.
Was watching it last night - basically an almost stationary blob of rain and storms rotating on the upper low.
Been basically raining in the same area since yesterday arvo, so there would be much bigger falls in the area between Woomera and Coober Pedy but no stations in that area.... Both EC and CMC had 50-100mm progged in the Mt Eba area overnight, so that one will be good to watch when the manual obs come in...
