Topic: Storms (incl night waterspouts) and Rain NSW / QLD : 7-8 Sep 2009

[Colin Maitland]

We have storms predicted for this afternoon then tending towards thundery rain later this evening. Ran the skewT analysis for forecast max and dew points and at this early stage it is showing the possibility of severe storms. Need to see what the analysis will be with the new sounding just after 11.00am. It could be a good afternoon in SEQ.

Col,

No doubt there should be storms around though I am very concerned about 'better quality storms' based on the mass of cloud cover. I would probably assume based on the models that the soundign will eventually show almost railyway tracks (moist sounding) in the mid levels. Not something I enjoy seeing on soundings.

Some action on the SW outskirts of Sydney now. Will it survive the drop off the escarpment into Wollongong ?

Pity the new Terrey Hills radar is not online till Wednesday.

Thunderstorms now in the grafton / Stanthorpe area now and the lightning tracker are going crazy in places. Maybe a nice storm.

A terrific storm just passed through here! Crop saving rain for many farmers who up till friday night had not seen rain for two months. Plenty of CG'S in this storm and thunder but have been unable to see anything all afternoon other than cloud cover. Was caught of guard as I had been driving around looking for a sign other than grey cloud, just came out of nowhere and passed in ten minutes!

Regards,
Chris.

That front Chris is just about upon us in Brisbane. No warnings as yet but looks like plenty of rain.  Northern NSW should be getting this rain as well and might put a bit of rain in Michael Baths water tanks.

Just watched Tim baley on the channel ten weather he was standing outside with all the cloud to ground lightning in Sydney harbour. Looks wild.
some lightning here now just saw my first cloud to ground south of us maybe Evans head area.

Once again the main rain band has decided to bypass us and hit Brisbane instead. I can't see any real visible lightning towards that way because the atmosphere is cluttered with low cloud.

It's hard to say if the storms contain any significant hail, being Spring and all though I would imagine there being some.

Thunderstorm - Western Sydney 7/9/2009:

A thunderstorm did pass across Western Sydney between 5.20 pm and 6 pm and another separate thunderstorm cell passed to the south.

However the storm that passed over Western Sydney was moving reasonably fast but did not drop substantial rainfalls.  The highest rainfall total occurred at Toongabbie with 4.5 mm falling, 4 mm at Northmead, 2 mm where I live in Blacktown and 2.5 mm at Seven Hills. Most other totals were light as well.

Driving home at the corner of Church Street and the Great Western Highway intersection Parramatta, some very large raindrops started falling at around 5.35 pm. This was followed by a brief downpour but a few minutes later the rain ceased. There were some moderate winds in that area (Great Western Highway) accompanying the rain but no hail fell. I saw one cloud to ground lightning strike and some intra cloud lightning. I noted heavier rain falling just to the north of Parramatta City Centre.

My friend Rita driving in Epping advised me she experienced a burst of heavy rain and some small hail in that locality. I also heard on the radio a few reports of small hail occurring at locations generally East of Seven Hills and around Parramatta as the storm passed over.

I was at work so missed everything, But the Sutherland shire had heavy rain and some minor hail.

[Steven]

Wow. I retract what I said earlier as we just had the heaviest rain seen since the May rain events, I'm sure. Can't understand how the airport didn't pick up anything out of this but it was rather isolated. I'd presume 20-30mm of rain has fallen locally which is a good thing considering how dry it's been.

Hi,

Chased the storm near Campbelltown - was in position for it to come through. I did get the tiniest hail but I was just south of the main core really - very difficult to chase in Sydney these days - too much traffic. But the gust front was half decent though elevated somewhat.
