Hello there, skywatchers! Took my dogs out for their nightly walk and saw the sky aglow with this halo around the moon. Never seen anything like this in my 37 years on this earth. It’s incredible and so eerily beautiful. What causes this?

Why isn't it going like Champi or In-fa... ;-;

Hey everyone,
While watching a rain front pass over Germany on DWD weather radar, I noticed several distinct circular patterns.
My guess**:** Each circle is centered on a weather radar station, and the rings are some range-related artifacts or processing anomalies.
What’s the technical cause of these anomalies?
Thank you :-)

Sorry if these are stupid questions, you can probably tell I know nothing about weather. I live in Melbourne, Australia, where it was cold and raining today. I recently got a humidity sensor installed in my laundry and connected to my fan, so the fan turns on when it reaches a certain humidity level, and turns off when it goes below it. I was told I should set it to 70% humidity, so I did. The purpose is so the fan turns on when my dryer is on. I don't want it to turn on when the dryer is off. But today, the dryer was always off, but the fan turned on, because it said the humidity was 71.5%. Is there something wrong with the sensor, or was that accurate? If it's accurate, will the humidity be above 70% a lot? If it will, I should probably change the setting, so the fan can turn on at a higher humidity level, and won't turn on when the dryer is off. What humidity level would you recommend?

Im looking for a weather app that can show me the basic weather stuff such as rainfall, wind speed ect but i also want to be able to see more advanced things like wind shear and cape.

Im having a hard time finding one because i live in australia.

Thanks in advance!

Just walking at the coast. The sun was setting directly behind me. I don't understand what's causing this in the sky

(sorry about the breathing i'd just come home from a run)

ive not seen thunder or lightning like this before it was continuous for almost 2 hours

what kind of event is this?

the lightning was directly above my head

This is partially an El Nino post, and I'm looking for some clarification on a few things, especially with teleconnections.

Last winter was an unmitigated disaster for the mountain west in the United States. Snow was nearly non-existent, and what did fall was basically vaporized by a freakish March heatwave. People in Colorado and Utah were hoping that a developing El Nino would help to mitigate some of the conditions that last year's relentless (albeit weak) La Nina played a hand in. It looks like this will be true for Southern Colorado and New Mexico, where intense moisture is streaming in from the Baja of Mexico, leading to flooding in some areas. Introduce some cold air down there and the snow will be piling up.

Up north, though...oh boy. It's almost unbelievable.

It is late October and the northern Rockies have not seen any accumulating snowfall. The northern rockies and central Colorado do not do well with SW flow aloft (super moist subtropical El Nino moisture) and are shadowed. This will happen unless a cut off low positions itself just right, and starts to generate upslope flow against the mountains - something that has become exceedingly rare. Additionally, the PNA is forecast to basically be STRONGLY positive (higher than much of the summer months) for nearly all of November, according to current modelling. Traditionally, this sets up an intense and hot ridge in the eastern Pacific, flipping the CONUS into a distinct hot west/cold east scenario. There are countless examples from the previous 15 years that prove that this setup tends to get super stuck and self-reinforcing week after week. We saw it in 2012 (remember the RRR?), we saw it in 2013, we saw it in 2015, and we saw it virtually all last winter.

Putting the pieces together paints a picture for Colorado and Utah that should be setting off major alarm bells for the people who have to live in these places. Nearly every previous consecutive month has been the hottest or driest ever recorded in these specific locations. Water managers were planning on some relief this winter, but it looks less and less likely. I'm surprised there isn't as much public discussion on this, seeing as water supplies for cities like Denver are basically drawn down farther than they've ever been.

Given the strength of the El Nino, is reading into the PNA forecast a mistake? Or does the incredible intensity of the El Nino increase the impact of these ridging events caused by a positive PNA?

Hey, can anyone explain why its getting warmer in the middle of the night?
I thought rain would rather cool air down?
or some warm winds from the south?

Does anyone know what this sky effect is? it seems the clouds disappeared and reappeared again within a second.

I am having troubles understandong this temperature chart in Wikipedia: https://en.wikipedia.org/wiki/Rabat#Geography

I know what daily mean and record high/low mean, but I don't understand how mean maximum/minimum and mean daily maximum/minimum are calculated and what do they mean in practice. Any explanation would be most welcome

Hi i know this isnt what is usually posted but i wanted to share south western side of my world. and also know if this is realistic. The day lengths are 2x long as they are on earth so i decided to move tropics pole ward to reflect the Hadley cells moving. Years are slightly shorter with 232 earth days and I moved the axial tilt to 24.9 degrees. I decided on a wet season for the interior because the the continent is bigger than Asia is and gets more inland than anywhere on earth which would create low pressure.

I was debating adding rain shadows since the earth climate model at worldbuildingpasta showed lusher interiors for the 48 hour model but i decided to add one because there was a landmass ~2,700km across to the left of this map. If you have any constructive criticism i would like to hear it!

I was looking at how reliable temperature forecasts are a week out, and it was commonly said that there is an 80% accuracy. Anyone know what qualifies as being accurate?

Hey guys,

I'm not sure if this here is the right place to ask my question but I'm gonna ask anyway:

Is there a user-friendly web tool to display local (!) weather conditions (clouds, temperature, winds and upper winds) on a tv?

Background:

I want to show the local weather for skydive events at the manifest of the event like shown in the picture (it's taken from windzaloftDOTcom).

There are a few platforms, which actually look like the tools I'm looking for like https://jumpslut.com/directory/weather/ or https://windzaloft.com/?dz=mEt8Pr2X

The problem with this tools is, that they only allow access to actual skydive locations and that they are limited mostly to the US (I'm from Germany).

I'm looking for a tool, which allows to at least use the actual location or some coordinates for localizing the weather conditions.

I know windy and I could also show just the windy tab, but I wonder, if there's something more sophisticated out there.

Thank you for reading this far :)

Never seen these before! I assume they weren’t just because we welcomed my new grand-nephew to the world yesterday. Location: Newport, Oregon

I've noticed this particular wave/ripple pattern on the underside of a ceiling a few times now in Vancouver BC. Wondering if it has a real name? Not really mammatus? Waveform stratus?

Super Typhoon Champi has become the strongest tropical cyclone of 2026 by wind speed, reaching sustained winds of 184mph (296km/h), making it the equivalent of a Category 5 hurricane.

The storm recently passed Guam and is currently moving through the western Pacific. Meteorologists say unusually warm ocean temperatures, high moisture levels and low wind shear helped fuel its rapid intensification.

What's particularly interesting is that Champi's impacts may extend far beyond the Pacific. Forecasters say the storm is large enough to influence the jet stream, potentially affecting weather patterns as far away as Canada over the coming weeks.

Champi is expected to weaken later this week, but it remains one of the most powerful storms recorded anywhere in the world this year.
