Look at this #derecho, or long-lived thunderstorm windstorm, EXPLODE in size. That's how they work. A small cluster of storms will tap into jet stream momentum, fan outward into a bow, and rush east to gobble up the extremely warm, humid air mass ahead of them. Textbook result:

[Showers/Isolated t-storms later today] A cold front will result in showers & isolated t-storms to work into the region from west to east later today. Pockets of heavy rainfall are also expected which may result in some poor drainage street flooding.

The jet stream will send several low pressure systems towards the UK this week. A subtle shift northwards in the jet stream later in the week will result in pressure rising in the south and temperatures climbing into the mid 20s Celsius for some of us 📈

This is normal where it is hot and humid. Cold air circulates into humid air in the cabin. Think of it like how cold air escapes when you open your fridge. 📹: Raised-Right

The amount of convective available potential energy over the Middle East on Thursday is enough for a textbook hatchery of supercell thunderstorms. Where this unstable mass of nearly 5,000 J/kg of CAPE intersects with the dip in the jet stream will determine the greatest threat area for desert tornadoes (most likely in the UAE, Qatar, and Saudi Arabia) and/or strong marine waterspouts over the Persian Gulf.

After a cool feeling weekend for some of us, things are set to change as we move into the week ahead. A change in wind direction by mid-week will likely bring some very warm and humid weather our way 🌡️ This may come with the risk of some heavy and thundery showers though 🌩️

Everything is stuck! That partly explains the 20” of rain along the Carolina Coast and extreme rains and snows in Central Europe. Take a look at the jet stream in the US and Europe. Rex blocks (high over top of low) abound with an extremely wavy jet stream!

After a settled spell of weather, we see the return of the jet stream this week. This fast moving ribbon of air high up in the atmosphere often dictates the UK's weather. A strengthening arm of the jet stream has the potential to develop a deep area of low pressure by Thursday.

There is NO END IN SIGHT to this brutally Cold pattern, with multiple waves of Arctic air likely to continue pouring into the U.S. well into mid-December. The Polar Jet Stream will keep diving south again and again, dragging down round after round of frigid Canadian air. This is the kind of cold we normally see in the heart of January - seeing it this early is highly unusual. Temperatures will run 10, 20, even 30 degrees below normal, and some locations may drop below zero for a prolonged stretch. Wind chills will be even worse. Bottom line: ⬇️ The cold isn’t going anywhere. Bundle up… it’s going to be a long, frigid stretch. 🥶

While it'll feel warm in sunshine this week, the real key for warmer weather is when the jet stream heads northward. And look what happens at the end of this week...

Sunny skies in the east this afternoon and feeling warm ☀️ Temperatures will climb into the mid 20s Celsius 🌡️ Cloudier further east with showery outbreaks of rain in places 🌦️

💥 In Tver, UAVs attacked the Migalovo airfield. ✈️ Due to the threat of an attack, the Russians raised their planes into the sky, and the local air defense tried to shoot them down. Unfortunately, they did not hit. ❗️In Tula, a residential building was damaged as a result of the work of the Russian air defense. 🤔 The Russians claim to have shot down 205 UAVs in 13 regions.

Normally I wouldn’t be this interested in chip tech, even considering this is impressive. Huawei has found a creative workaround to catch up with the likes of TSMC. But what makes it even more compelling to me is the bigger story and resilience behind it. Starting in 2019, Huawei faced intense sanctions that significantly restricted their access to advanced chip technology and global supply chains. For a while, it looked like this would seriously damage or even sideline them in major way. A lot of people thought the company was done or would be stuck far behind for years. Yet Huawei refused to die. Pushed hard by those challenges, they didn’t fold or give up. Instead, they dug in, poured everything into self-reliance, research, and fresh thinking. They reinvented how they approach problems and entered a whole new era of innovation and creativity that probably wouldn’t have happened this quickly, or maybe even at all, without being forced into that corner. That’s the part I find truly inspiring. When the pressure was at its heaviest, they turned obstacles into fuel. They focused on what they could control, built up their own capabilities, and came back stronger with real breakthroughs. It’s rare to see that kind of determination pay off in such a visible way. So many observers probably believed the sanctions would destroy them or at least slow them down permanently. Instead, they lit a fire under the whole company and sparked a level of ingenuity that feels genuinely exciting to watch unfold. Sanctions were supposed to end them. Instead, they pushed Huawei into this impressive new chapter of self-reliance and forward momentum. That kind of comeback story is exactly why I’m such a big fan and why moments like this announcement feel so satisfying.

Lots to unpack in this loop from yesterday's flood - notice how the Kerr County floods were initiated by stationary thunderstorms with torrential rainfall rates, followed by a second round as a cluster of storms to the north grew into an intense mesoscale convective system (MCS):

Scattered storms are expected to develop in the next few hours and could quickly become severe with large hail up to golf ball size or larger and damaging wind gusts of 60+ being the primary risks. I will have all severe weather alerts and tracks of the storms as they come out.

From the cold, rainy shadows of loneliness to the warm glow of kindness, one small treat and a gentle touch turned tears of sorrow into a smile of hope.

Look at the difference in the physical size of Reagan’s agents, their situational awareness, their reaction speed to gunfire, the way they muscle him into the vehicle, and how quickly his vehicle takes off. 40+ yrs of additional training and Reagan’s detail did a far better job.
