Spectacular strong storms impacted the Katherine to Daly River regions as convection fired above a stout cap due to the dry and hot change. Pell Station, Adelaide River NT
Non-convective induced mammatus clouds. Very often, mammatus clouds transition to virga and then falling rain as in this case. Light rain showers barely recorded anything in my rain gauge. It looks threatening but is only a great weather photo op.

Here's another prime location, Kluane (pronounced Kloo-WAH-nee) National Park, in Canada's Yukon. It's a true northern wilderness, and I did multiple backpacking trips there in the 1980s.
On this multi-day hike with my then-girlfriend, we went up Fortyeight Pup Creek, on the lower slopes of Sheep Mountain, and camped on the open tundra. The day was sunny and warm. Next morning, we woke to rain and fog, which persisted all day. Then, the next day... this! The clouds began to break up, patches of sunshine lit them here and there, vistas of endless mountains started to appear. It was like a curtain being lifted. I was spellbound, but luckily remembered to grab my camera and shoot.

I decided to make some Cauliflower Steaks for dinner. I just love these. The recipe is so simple and they are so delicious.
Thunderstorms
What is a thunderstorm?
A thunderstorm is a rain shower during which you hear thunder. Since thunder comes from lightning, all thunderstorms have lightning.
Why do I sometimes hear meteorologists use the word “convection” when talking about thunderstorms?
Usually created by surface heating, convection is upward atmospheric motion that transports whatever is in the air along with it—especially any moisture available in the air. A thunderstorm is the result of convection.
What is a severe thunderstorm?
A thunderstorm is classified as “severe” when it contains one or more of the following: hail one inch or greater, winds gusting in excess of 50 knots (57.5 mph), or a tornado.
How many thunderstorms are there?
Worldwide, there are an estimated 16 million thunderstorms each year, and at any given moment, there are roughly 2,000 thunderstorms in progress. There are about 100,000 thunderstorms each year in the U.S. alone. About 10% of these reach severe levels.
A Qantas Airbus A330 approaches the Equator on the Sydney-Singapore route. Unsurprisingly there was some turbulence from tropical convection.

These threatening looking clouds occurred well after severe weather moved through southeast Wyoming. Between 2;30PM and 5:30PM, I received a steady moderate rainfall totaling 0.70". These mammatus appeared within a half hour of sunset and more than 3 hours after the rains stopped.
Looking east to southwest.
I believe this is: Altocumulus stratiformis opacus mamma.

A punishing cloud builds up in the afternoon heat and humidity!
This is one of the better build ups to the storm season just passed in the Kurrajong/Hawkesbury area.
As a follow-up to yesterday's photo, this photo was taken exactly 3 hours later near the town of Benjamin, Texas. The storm was slowly dying out at this point, as the sun had disappeared, taking the convective energy with it.
But the lightning was gorgeous as it slowly moved our way, and I loved how it blasted through this flat deck of clouds.
At the end of a stormchase in the northern Texas panhandle we were rewarded by nature with fantastic colours caused by the light of the low sun.
Got one! This time I was in the right spot for once. Last time, the storm caught me!

First chase of the year wasn't a bust, so that's great...got to see some pretty wild structure here east of Monahans, TX yesterday after the sun was down, which should make for a fun time-lapse! Great to shake off the rust and see some nice convection. Back at it today, really want to play some dryline stuff in NW TX, hoping it pays off.
Que dire sur cette nuit mémorable, arrivé à 23 h puis rentré à 3 h, j'ai eu la chance d'assister à un magnifique spectacle kéraunique. C'est avant tout la réalisation d'une composition photographique tant désirée : foudre(s) et Baux de Provence. Une pensée pour les bretons rencontrés en arrivant ! Je pourrais écrire tellement de choses sur cette nuit, mais restons simple !

What to say about this wonderful night, 23 pm to 3 am by contemplating this lightning show. And it's the time to achieve something : a composition with the Baux de Provences. A tought for the person I met this night ! I could write a lot about this night, but let's be short !
5 Août 2017 - Les Baux de Provence.
More often than not it seems that the North Park area in Colorado experiences dynamic weather, on this day there was strong convection and rapidly passing showers creating a fantastic mood from the crazy cloud-filled sky.
Fast moving convective cell dropped only a trace of show but visibility briefly dropped to a few hundred feet. At top, you can see a few flakes lit by the bright emerging sun.

Some convection over the Cheyenne Ridge (borders Colorado with Wyoming). These cells dissipated after max heating occurred. Reached 70F after the previous day's high temperature was only 39F.
This red painted house really stands out in my neighborhood.
In the summer, afternoon convection produces storm clouds over the high desert. They roam across the landscape, dragging tendrils of rain that never quite touch the hot dusty surface. It's a lonely sight. Those that move into the higher elevations grow stronger, producing dry lightning. Those strikes do touch the ground. Starting wildfires.

Slow convective build-ups (cumulus congestus) encompassed the entire sky by mid afternoon. The ragged cloud bases could only generate virga since the air below was quite dry. Radar returns were showing rain never reaching the ground.

Calvados - 3 Octobre 2013
En cette journée, le potentiel convectif et les prévisions étaient au beau fixe. Après un premier passage en matinée, le reste de la journée fût plutôt calme.
C'est en début de soirée que des premières cellules prennent naissances dans les terres, très vite la situation évolue. Sous ce premier passage le tonnerre se fait entendre et la foudre se montre en arrivant sur la mer. Mais très vite cette cellule perd en intensité. La frustration nous gagne, ce fût un peu court... Ce n'était sans savoir ce qu'il y avait de cacher derrière elle...

The storm was just beginning to boil. Soon I would be under it and witnessing a spectacular green core with lots of lightning.

Superbe orage d'air froid qui s'intensifie en abordant la côte, à l'exemple de cet aveuglant coup de foudre positif. S'ensuit un éclatement et roulement bien caverneux. Ce système multicellulaire offrira à la côte de Nacre une belle chute de grêle pendant plus de 45 min.

Beautiful cold air mass storm, getting stronger near the coast with this intense positive strike. Strong and cavernous thunder some seconds after the hit. This multicellular system gives a hail for more than 45 minutes.

Very dry surface air prevented any precipitation from reaching the ground. Convection was also non-existent. I captured this on time lapse: www.flickr.com/photos/79387036@N07/51165371329/in/photost.... Taken 7 May (late afternoon).
Used Fujifilm T-X3 with 16-55mm f/2.8 @ 16mm. The HDR was created by bracketing exposures from -1 to +1 f-stops at 1/3 increments. This resulted in improved color and contrast. I usually avoid HDR but sometimes the lighting requires using this technique.

Strong convection over my neighborhood and yet this storm produced no rain, hail, lightning, wind, etc. It just sat there for over an hour as my GoPro clicked away.
Oh BTW, the brown smudge at the center was a small blade of grass at the center of my lens. I have to be more careful before using lenses. Fortunately the clip wasn't ruined.
A YouTube video clip reveals the evolution of the weather as the afternoon progressed: www.youtube.com/watch?v=up9g5DTs7Zo. Worth watching!
Annual hopes for some convective excuse to get drawn up to the northern, high plains are ramping up. Especially after last year when it wasn’t even an option. Cauliflower on bountiful greens, from 2018 thirty miles down an unpaved road east of Judith Gap, Montana.
Possibly too many leading lines happening here—from May 23rd north of Genoa, Colorado. The tail end of an ongoing line of storms is on the right with new development offset further back to the left. RFD surges were kicking into that line in spots, and a tornado dipped out of one about 45 minutes later.

After a brilliant fire sky sunrise, the sky was quickly covered with a cirrus overcast and a lenticular cloud beneath. After the lenticular dissipated an hour later, the sky erupted with non-convective mammatus clouds: www.flickr.com/photos/79387036@N07/51623642329/ and www.flickr.com/photos/79387036@N07/51622991621/.

FR : Retour sur le 29 Juillet 2013, avec cette belle et sombre structure abordant la mer en fin d'après-midi. Très esthétique et d'une atmosphère bien pesante. Peu active, cette cellule a offert un intra-nuageux suivit d'un coup de tonnerre.
ENG : Back on 29 th of July 2013, with this beautiful and dark structure reaching the sea in the end of the afternoon. Very esthetic and a heavy atmosphere. A soft activity, this cell gave an intra-cloud followed by a thunderclap.

Food
This will be one of the last meals I'll be preparing in this oven since I'm getting an induction range later this month. It has an air fryer/convection feature built into the oven. I am going to enjoy it a lot.
Whole, frozen local sardines, that I had to scale and gut — pain in the bum, but worth it.
Marinated in a mixture of olive oil, lemon juice, Maggi sauce, salt, pepper, harissa (a North African chilli paste), ground cumin, ground coriander, and Raz-el-Hanout for about an hour.
Then baked in a microwave at #1 micro, convection 180°C (355°F) covered for 10 minutes, then basted with the marinade and cooked uncovered for another 10 mins.
On a bed of couscous, cooked, fluffed, and combined with a mixture of olive oil, lime juice, salt, pepper, chopped parsley and mint.
Topped with cilantro leaves.
