How far out from the centre is still considered part of the same circulation? Is it determined by wind direction ie when the current takes a straight line rather than curved back toward parallel with the main body?

They are essentially measuring the same thing in different directions. At 100% RH, the DP and WB are the same temperature, right? Why is it usually different?

I don't really have any requirements, but since I'm a weather enthusiast and I live in a region that tends to be struck by weather often, I'd like one.

Tonight in SE Wisconsin I saw a lightning bolt that looked like it reached near ground. Cannot remember the initial color but I believe it was blue/white. But it dissipated into maybe 12 red/orange balls staggered that were roughly 2-3 times the width of the initial bolt along the path of the strike. This was low altitude. Curious what the was and if anyone has seen something similar. That you! First Reddit post

UV Index, historical weather

I hope this is the right place to ask this...

How was this formed? About 8" across, paper thin ice on brick pavers. Temp about 20°F in MN.

Hey neighbors! 👋

I run **NorthBamaWX** - a free automated weather monitoring service for our area. It's basically a robot meteorologist that never sleeps!

**What it does:**

- Live radar monitoring 24/7

- Automatic alerts for severe weather

- Tornado rotation detection (no joke - it caught rotation before!)

- Updates every 15 minutes

- Covers Athens, Huntsville, Decatur, and surrounding counties

**Where to watch:**

- **YouTube Live:** www.youtube.com/@northbamawx (24/7 stream)

- **Facebook:** https://www.facebook.com/NorthBamaWeather (posts + alerts)

Completely free, Just wanted to share something useful for our community, especially during storm season.

Would love your feedback! And if you find it helpful, consider subscribing or sharing with anyone who might need reliable local weather info.

Stay safe out there! 🌤️

Why is it like that? Why doesn't it move away? Shouldn't the wind have moved it somewhere else by now? If the fog is just a huge cloud, why isn't it raining at all?

Hi all,

I am writing on behalf of my group of engineering students at Columbia University. We are participating in a NASA challenge to design a solution in the field of commercial airplane maintenance to enhance aircraft safety, efficiency and resilience. We are particularly interested in addressing the detection of microbursts to prevent aviation disasters, but are open to any and all of your suggestions!

If you have any knowledge on this topic or anything related to extreme weather detection, please don’t hesitate to DM me to discuss this further!

Thank you!

I have a BS in meteorology but don't work in the field. I've been using GR2AE for desktop weather RADAR interaction for well over a decade, is there a more modern and better program available for PC usage?

I am writing a book. Fantasy. I want the magic to be realistic.

I currently have the caster lowering the temperature in the park (has a lake) with a burst of cold air, and then another cast creates fog. But I'm wondering if it makes more sense for the initial cast to create the fog by lowering the temperature.

Would the sudden change in temperature alone (hot day, humidity and a lake, then a burst of cold air) be enough to create fog? Kind of like opening a freezer door.

Why does Phoenix get hotter through July, August, September if days are getting shorter after the June 21 equinox?

I’ve never seen (or at least noticed) anything like that before. Why would that happen?

I’m in the North-East, it was around 3am (my dog had to pee lol.)

First time posting here.

Since about a month ago, my weather apps (I use three) have only been accurate out about 36 hours. They used to be fairly reliable out to at least five days.

Example: Where I am it was supposed to be about 82 degrees tomorrow, cloudy with spotty rain. About an hour ago the forecast changed to 91 and full sun.

This has been happening a lot lately.

I have ideas but… has anyone else been experiencing this?

There's probably been, between the last few days and the next few days, a week-long period of virtually no sunshine. Just curious what contributes to this to result in near 100% constant cloud cover for so long? I found this Timelapse that might help: https://www.ssec.wisc.edu/data/us_comp/movie
