Yes Ken, I agree. The sea breezes play a huge role in the summer storm season in Florida. An interesting place to watch along with Lake Okeechobee is the entire Tampa Bay Area. I was actually lived in St. Petersburg which is located in Pinellas County, which itself is a peninsula. Not only do you have the sea breezes from the east and west coast of FL meeting up, you also have bay breezes coming into play, especially on days where the prevailing winds are light and variable. The Tampa Bay Area has its own little micro climate going on which can often times produce localised mid day storms, and then have the main action late in the afternoon push in from the interior of the state from the east. Very lightning active indeed. In fact, just east of Tampa along I 75 in and around the Brandon/Plant City Area is considered lightning capital of North America. I have many fond memories of the summer storm season in that part of the world!

I might have showed you this before, but a great place to watch the Atlantic Hurricane Season is www.myfoxhurricane.com
Also, www.fox13news.com weather section has an awesome radar system with live radar and lightning of the entire Central Florida area.

Sorry to ramble on about Florida when we are a half a world away, lol.
It is amazing how dry the air has been here. Yes, our daytime temps have been above normal, but our nights here have been very cold with many many nights well below freezing. We are expecting 30 degrees here in 7 days time. Our lows are also expected to warm to above normal by then. It might be a bit too early in the season to call this winter over, especially in this part of QLD.

When averaged out, it ended up a bit wetter than normal but much of that was due to a very heavy rain event in May of that year which caused severe flooding in some areas. Then by late winter, it became extremely dry when the extreme heat set in and we had a massive streak of rain-free days.

I don't mind it at all personally...I've always found the weather in the US far more interesting and with far more variety than here anyway smile

11th frost of the year this morning... need 3 more to reach average but I don't think we'll get any more for awhile in my local area.

Here's my frosty thumb and scraping ice off the bottom of my boots yesterday:

Here's some images from that infamous east coast dust storm in September 2009.

I remember the exact date it arrived in Brisbane and Sydney very well because it was on my birthday.

Of course, big spectacular dust storms aren't rare in the outback and often affect small outback towns but rarely make headlines.... but as soon as it hits a major city like Brisbane and Sydney or the east coast in general, it's saturation media coverage and in this case, made international news as well:


Aerial shot:





Perisher ski fields covered with dust:





PM10 particle concentrations in the air in Brisbane when the dust arrived:





Multispectral satellite imagery enhanced to show up dust:





CNN (visibility was much lower at times than what the photo shows):





MODIS satellite imagery of the duststorm:

From around 10 days time or so from now, looks like temps might come back down with another westerly burst just in time for the end of the Ekka... but not before that sustained period of the incredible warmth/heat.

Here's an output from the GFS ensemble run yesterday (not sure why it's dipping so much on Monday... might be due to a few crazy outliers dragging the ensemble mean down). EC ensemble is similar:

I find it interesting that the Florida coast-line (similar lattitude to about Brisbane) can get so cold despite the warm SSTs surrounding it. On the day of the Challenger launch (Late Jan '86), temps dipped to the low 20sF the night before (around -4 to -5C) with icicles 1 metre long forming on the launch pad. Not sure if any coastal town in Aus recorded temps that low before, perhaps TAS as they can get sea-level snow.

The coldest place in SH is Antarctica, and there is a ring of ocean surrounding it which keeps the polar vortex tighter, and if air does plunge out of the polar vortex it has to cross this ocean and the cold temp is moderated. In contrast the coldest place in NH is greenland, with north Canada and North Russia not far behind. The ocean is on the pole, so the pole is not as cold, which means the cold air can escape the polar region easier, and when it does escape it doesn't need to cross an ocean.

Melbourne's lowest recorded temp is -2.5, which is lower than a couple other places in SW WA and south coastal Vic that I've checked. I'd guess that as it only has partial exposure to the ocean as a bay it can get colder than other coastal locations further south.

Hobart's lowest is -3.9.

Brisbane City 2009 rain 1072mm, average 1042mm, April and May did quite well, before drying out big time with a dust storm in September.

I remember the storm season of 2009/2010 quite well as I was desperately hoping for a repeat of the incredible storms in late 2008 (Gap storm and others). It was very dry during spring. We had little storm activity and most of it was in far inland SEQ. Was disappointing.

The dust storm was incredible though. One of my all-time favourite weather events. I remember Brisbane had a less severe dust storm around 2001 which came in the evening. But the 2009 dust storm was incredible especially as it came during the day and was such an eerie red. It lingered for a few days too. I'm not sure when we'll see another one like that again. We just haven't had the long-running drought conditions of the early 00s to set one up.

That probably explains why the cold front's can penetrate a lot easier into Florida compared to similar latitudes down here? The fact we have no major land mass between southern Aus and Antarctica. Be interesting to see how our climate would differ if we had a land mass similar to North America.

I don't mind your stories at all and i'm always interested in North American weather. When did you move to Australia? It certainly would be a unique part of the world having sea breezes coming from different directions, and on top of, the Florida region get's some pretty decent water spouts as well.

Ken thanks for those pics and maps of the 2009 dust storm. I had no idea Brisbane got affected as well, I thought it was only the Sydney Region.

Two even better dust storms for Brisbane in Spring 1964.

Great pics ken. I thought on that day of the dust storm that this is the worst our 10 year drought will get and it was the turning point because after that, things just got wetter. Sometimes you have to get a horrific thing like that happening that usually signals a turning point. But unfortunately we will keep getting these over the years. We save water and get penalised for it- how's that. A bit off topic, as i did think this is exactly what was going to happen when we used less water and electricity, prices go up. 2 significant items, one for conservation and the other for climate change. Its just not worth it anymore trying to make a difference so lets just burn everything(Coal) and leave our taps running smile

Should easily hit low 30's for the northern rivers, in places where there will be no seabreeze like Casino.

The hot spot is in fact Evans Head, surprise, surprise. (now 30.3C)
That station at the RAAF bombing range, just tucked away back from the coast, always gets the money.
Places like Yamba Pilot Station have 360 degree ocean exposure, so will very rarely get it.

This run of unseasonably warm maximums with still reasonably cool mornings has me wondering about daily temperature range records for SEQ, well elsewhere in Australia also. I remember many years ago one day in early September, the day of the School's German Festival, where we had a light frost in the morning and then in the afternoon a howling NW wind took the max. to 28-29. Some folk I knew from out near Pittsworth went from a minimum of 2 up to 32 on the same day. Perhaps Ken or anyone else with access to daily temp. records might be able to fill me in. Felt like Summer just now when I just walked out of work to get some lunch. Weird Ekka weather for sure.
