The faintest of mizzles falling here now. Waiting for the full on mizzle fest in anticipation!!!

This mizzle is precipitating from very low cloud bases, which is the reason why the radar isn't picking it up. The radar sends out a radio signal which will "bounce back" off precipitation. If the radar beam passes over the precipitation, it won't get any reflection and nothing shows.

It has been drizzling or raining lightly almost non stop here on the Central Coast since about 3:00 PM yesterday. It really should learn to rain more efficiently in the Sydney area. 30 hours of gloom for a few millimetres of rain is ridiculous. Sydney seems to have been drier at least until the second innings of the One Day International got underway.

Cricket is over but they had no precip for an hour. Over this lame crap, bring on the NRL season.

Hey Steve-O, it's forgotten how to rain remember, so give it a break- it's just learning the ropes poke.

Anyway, a good 30 hours of mizzle does wonders for the garden- any heavy rain would just run straight off at this point. Down here we had 1 mm yesterday in about an hour and less than half a mm from tonight's mizzle which has just stopped (again roughly an hour). Amazing how much wetter it can be on the Central Coast and Hunter.

After Friday, I love this crap. Cloudy, overcast, mizzle/drizzle and temps in the very low 20's. Can't beat it in the middle of summer.
It may ruin a cricket match or two , but not as much as John Inverarity and his selection policy does.
Anyway, WSWanderers are on fire, and they are giving me my football fix over the summer.
So are these guys.

My take on the first 2 days of the week ahead

Monday is mainly a ranges chase day with the wind shear through all levels expected to be quite slow, the compression of air masses as they flow over mountainous regions is as good as gold in terms of setting a favourable wind shear environment for storm cells on this day.

Pulse type storms which are not usually renowned for being long lived are expected, slow moving and should carry plenty of rain in them so fires as a result of lightning are a low chance.

Our Upper atmosphere is on average around 6c cooler then last Friday and a beautiful NE surface wind is expected to be active all the way down to Canberra by 2pm which as a consequence will flood surface moisture onto the ranges and should give convection a good kick in the pants.

The trough causing these storms is quite broad and expected to be aligned NNW - SSE stretching from around Traralgon, Vic into NSW via Cobar and well over into QLD.

A notable NW - NE convergence line is expected over Canberra, the ranges near Collector - Gunning might benefit a lot from this.

Being mainly a pulse storm setup near us for this day they will most likely be in a state of collapse as the sun sets and we lose heat.

Max temps in storm regions expected to be 25c - 30c (higher the further west you go) with dewpoints in the 16c - 20c zone (drier the further west you go but fantastic surface moisture!)

Recommended storm targets: Southern Highlands, Central Tablelands, Southern Tablelands

note: Severe potential for the Illawarra and surrounds is very low.

Tuesday

Wind shear is expected to be a little bit better on this day more so towards the 5pm - 11pm time frame where it increases due to pre- frontal interaction with an inbound Southerly change expected through the region around 1am Wednesday and storms could potentially make it onto the coast, the lower end of the trough moves NNE and orients between Narooma - Batemans Bay and runs out NW via Cobar and again into QLD.

Instability is again very widespread due to this broad trough.

Upper atmosphere temps could be a tad colder which is way better for supporting storms.

We're expecting higher surface temps and the coastal surface moisture should be good but it drops off rapidly inland with anywhere past Goulburn most likely way too dry on the Southern Highlands but the Central Tablelands expected to have much better moisture.

Notable convergence line is expected be on the Southern Highlands in the early afternoon extending a little further west and south as the seabreeze front gains it's grip on the inland which should definitely be the kicker for a lot of convection!

With a slightly more supportive environment shear wise and warmer temps expected into the night storms could keep going after dark up until the Southerly Change sweeps through the region (lightning pic potential night yay!).

Max temps in storm regions expected to be 30c - 32c with dewpoints 14c - 18c inland and up to 20c on the coast.

Recommended storm targets - Southern Highlands out to Goulburn/Bungonia and Picton - Bargo, Crookwell/Orange/Bathurst, Sydney Basin around Penrith - Richmond and the Illawarra coast, Hunter and Upper Hunter areas later in the day.

Severe potential for the Illawarra and surrounds is only slightly higher due to the still limited wind shear profile and lack of really solid upper atmospheric support, Storms will initially be pulse type but should start to move more later in the day, still the environment is not conductive to large powerful severe cells by any means.

No mizzle, or any sign of it here, again. Cool morning, overcast, lovely. When the sun came out, it wasn't too bad, I think we got to 29c, a bit humid but compared to 42c, almost pleasant (nice to be able to take a break from working in it though). Various types of E/SE breeze all day and the NE/E is quite strong tonight, 16.8c outside.

Put lawn bug poison on the grass tonight before the water came on, but some rain would be nice. or brilliant.

We ducked over to Blackheath yesterday - absolutely lovely after all the heat it was cool and drizzly. We had temps around lunch time of about 14 or 15 with a breeze and a very damp drizzle so I actually almost wished I had jeans instead of shorts and sandals - however we toughed it out as we do. smile

The funny thing the last couple of days was a brother visiting me from the Central Coast and getting me back by saying how come I lied about it being dry out here all the time because yesterday ended up VERY humid for here. smile

It's quite muggy again here today. Solid lowish level overcast pushing in from the coast.

Slightly hopeful of some sort of rain over the coming week.

That change that came through a couple of days back, the humidity rise was palpable, I have a thin polypro silk-look carpet, that felt actually wet (the dog got glared at). The humidity has evidently reduced, as the bills stuck to the fridge (which faces the eastern window) are all rumply from being moist, and then drying. Oddest thing.

Another lovely mild overcast morning, with limpid sun down in Canberra. Warming up, we're going to 32c today, and the forecast seems to think we'll be in for showers or a storm, but Opticast is lukewarm on the idea.

Sadly our overcast is busily burning off. The temp has been about 22 but will climb as the sun comes through. The clear line to our west has been steadily pushing eastwards and is almost here. Shame really, the 22 was nice.

Why sadly?
My rain tank is not getting filled.
My solar panels are not generating much juice.
Useless weather is this rainless overcast.

Why sadly - because I'm sick of the heat.

29 out here at the moment. At least it's cooler than last week.

I'd prefer 29c... they forecast 32c for us today, so it got to 34c...

Tomorrow is meant to be 35c. I hope it's 29c! I won't be in air con for a month once I leave work today. On the upside, after all this foul heat, from Aus Day onwards I'll be in minus temps in Utah. NOT acclimatised at all. Hope we get a cool down this evening, looks like the storms have given up on us.

It must be hard for BOM to accurately predict the maximum temps, I said to my work colleagues today that it would get to more than 32C & I was right...
the easterly is in @ Braidwood & Goulburn so hopefully you won't have to wait too long Ant.

Cheers Teddy

Lovely day today, the depressing muck from the morning cleared by lunch to a beauty summer day with almost 26deg max. Just loving this summer, only about 2 days so far which I admit were too hot one of which was last Friday, but all in all an excellent summer, I will have one of these every year thank-you.

The easterly was blowing as I drove home, smelled like water, but sadly it is not a cold one. Feels quite thick and humid, and it's 22c outside. Wind's dropped right off so cooling inside any further will be difficult!

Bureau has pulled back on some of the precip forecast for the week, too.

This is actually a Perth like summer with almost no rain which makes it better for outdoor activities. I would rather have the rain in winter so it can be turned to snow.
