Australia severe weather 2007/8 season

[Supercell Hunters]

Alot of heavier showers here yesterday arvo, scoring over 24mm here at Modanville, Nth Lismore. Went thru that heavier shower in car and friggin so heavy especially you see those in tropics monsoon! Absolutely belting down extremely hard and has to stop on road when it eases.

Today have a little instability, rain areas across NE NSW to put in very pleasant conditions and this helps the conditions to reach favourable to sleep well at night! Scored 1.1mm since 3am this morning.

[Supercell Hunters]

Now going to get humid again. Temperatures going back to high 20's with dangerously high dewpoints to tend 30 degrees plus humidity. More showers through everyday, only over 400mm so far for this month/year.

[Supercell Hunters]

Continuing extreme tropical conditions here in subtropical climate! Today was the insane weather ever experienced, but it tend to get more onwards. Nice showers today increasing to widespread showers to be heavy with local thunder, max temp was 30 with heat index of 32 degrees of 79% humidity! Very hot and sticky cloudy day with good heavy wise showers. Likely to see heavier and more widespread overnight into rest of the week and next week aswell compared to the forecasting models. This is due to convergence between the monsoonal trough and southeast trade winds. Going for 55m tomorrow and 20mm onwards. Gonna be wet and very hot cloudy days.

[Supercell Hunters]

Boring weather starts to leave sooner, rain coming back as radar showing even its going for first souther'ly change tomorrow! Yay! Bring it on! Very hot and muggy here still, 23 low temp and 28 high temp lately.

[Supercell Hunters]

Had a bit of extreme rainfalls past 62hours, had over 77mm since the 62hours. One night we had 68mm from extreme monsoonal downpour. Convective outlook going for showers and storms today with very heavy rainfalls due to slow nature of windshear. Rainfall for January/2008 is over 480mm!

Northern Rivers and Midnorth Coast.

Issued at 11:25 am on Monday 4 February 2008

A moist onshore airstream is feeding into a low pressure trough over inland New South Wales and resulting in rain over much of eastern New South Wales. The heaviest totals in the last two days have been on the Mid North Coast and Northern Rivers districts north of about Coffs Harbour.

Further rain today will add to the rainfall accumulated over the weekend and may result in local flooding in the Mid North Coast and Northern Rivers districts.

Flood Warnings are current for the Tweed and Orara Rivers.

A low pressure system may develop off central parts of the NSW coast Tuesday with localised heavy falls associated. This situation is currently being monitored and if necessary a Severe Weather Warning will be issued for coastal districts further south.

Huge fat massive squall line coming in! Looks like we gonna get slammed by hail and squally NW lies under it!

Squally north western lies moving through inner Northern Rivers area expecting to increase gale forces sustaining winds with gusts up to 110km/hr before reaching the coast. Main cores include local hail and flash flooding rains.

Likely to get slammed!

[Supercell Hunters]

Gust front hovering over us, smell of hail here i guess. Gusty NW lies inflow winds here now, reaching 70km/hr and getting stronger!!! Very nasty shelf gust front.

[Supercell Hunters]

Monsoonal squalls here so far, max gust around 60km/hr and rain is falling constantly since lunch but it a little heavier though. Over 45mm so far since 9am and marking over 300mm of rain for Feb and 850mm for the year! When would hit 1000mm mark hrmm?

[Supercell Hunters]

A bit of monsoonal squalls here last night with gusts up to 70km/hr, now winds back to southerly ahead of southerly change. Anyways scored 45mm since 9am yesterday and 4mm since 9am this morning from southerly showers. Now the showers becoming easing and winds for tomorrow.

[Supercell Hunters]

Continuing showery continues here last few days and temperatures finally getting warmer, expecting to reach into 30's during this week plus a possible another severe weather event! Showing a deep low pressure coming towards the coast on this week!

Synoptic Situation

A high, presently located near Tasmania, is moving slowly east and is expected to move into the southern Tasman Sea during the day. The high is directing a south to southeast airstream along New South Wales coast which will turn more northeasterly in the south. There is an increasing likelihood of the development of a deep low in northern Tasman Sea/Coral Sea during next week, with a hint that the low might track towards the Queensland/NSW border towards the latter part of the week.

February 18th

AUSTRALIA is facing a battering on both sides by extreme weather with a cyclone menacing the western coast as floods devastate the northeast. Residents are battening down or preparing to flee as category three tropical cyclone Nicholas bears down on the northern West Australian coast.

People in coastal Pilbara towns between Mardie and Exmouth are on yellow alert as Nicholas threatens to pummel the area with winds of up to 185 km/h.

Full report here

Updated Mon Feb 18, 2008 12:57pm AEDT

Evacuation centres are now in operation in Exmouth as the tourist town prepares itself for Cyclone Nicholas. Schools and businesses are also closing.

The Weather Bureau predicts Nicholas will pass west of Exmouth tomorrow morning, but generate gale force winds by as early as this afternoon.

Full report here

[Coast]

[Supercell Hunters]

Its very hot this morning....temperatures hit low 30's just after 9am and now (10am) reaching 33-35 degrees! The humidity is also high aswell due to 20 degrees plus dewpoints which might be a good sign for a storm this afternoon.

[Supercell Hunters]

Maxed out at 36 degrees at 1pm today before a strong to gust 55km/hr gusts southerly change and it kept the temp below 30's now! Alot cooler and very pleasant!

[Supercell Hunters]

Good old wintry type days here today, refreshingly cool day with gusty southeast winds but easing though with isolated showers.......'isolated' means for here is nothing to get otherwise you might ended up getting a freak monsoonal like shower especially we had 25mm from that last night!

Well it seems something for sure of rainfall total.....961.3mm of rain so far for 2008!!

[Supercell Hunters]

Very strange in last 10 days, heatwaves now added for central southern country now since the western had, so likely to move onto the eastern including here sometime this easter with severe storms redeveloping. Few severe cells near Canberra the capital now......blazing heat with many days over 35 degrees at Melbourne, Adelaide and Perth, much alot hotter inland including Broken Hill, Mildura, Marble Bar, Woomera, Port Augusta and so on. Here is just like spring like conditions with odd showers with Se breezes. Days r over 25 and nights sitting ducks around 20. Just pleasant in nights and very humid days.

[J07]

Do you really get "Monsoonal Showers" in Ballina? AFAIK, the Monsoon trough sits firmly around the Australian tropics north of 20S, occassionally delving down to north of Brisbane in exceptional circumstances. Coastal NSW/temperate coastal QLD is more affected by SE trades than by monsoon troughs.

[Supercell Hunters]

Finally might see some lightning back today, nice cells firing up on radar moving northwards along the weak souther'ly change with high humidity and dewpoints. Very nice updrafts and instability outside with some heating. Some towers out west has some features that having an anvil. Hopefully get something!
