Weather with Enthusiasm is a podcast about weather, atmospheric extremes, and climate (including little ice age)  created by Simcha Lefton. Documentaries and/or other interesting weather phenomena are released daily at 3pm Sunday - Friday and 10pm on Saturday.   Should you choose to become a member this material (the next weeks episodes)  will be made available to you immediately.   The show features passionate weather analysis, with a special focus on the Midwest, while also exploring major weather and climate events from around the world. Topics include storms, heatwaves, Arctic heat, climate change, the Dust Bowl, historical weather extremes, and occasional imaginative retellings of biblical weather events as if covered by a modern weather service. For the first five years, the podcast was entirely hosted and delivered by Simcha Lefton, with no AI content. Beginning in April 2026, the feed expanded to include some AI-generated episodes and segments, including daily Chicago zmanim and sunrise/sunset times, hyperlocal forecast episodes with detailed weather explanations, and documentary-style episodes. All AI content is clearly recognizable and part of the same broader project: making weather information and atmospheric storytelling more engaging, accessible, and wide-ranging.  There is also a focus on storm chasing including most likely location of triple-point (as of April 2026).  Whether you’re here for Midwest weather, Arctic anomalies, historical climate perspective, or creative weather storytelling, Weather with Enthusiasm brings it all together in one feed.

    Antarctica's Unprecedented Heatwave: A Global Chain Reaction

    Weather with Enthusiasm | Documentary Episode: "The Heat That Broke Antarctica" A documentary-style episode exploring one of the most extreme atmospheric events ever recorded. In March 2022, temperatures across East Antarctica spiked 38–40°C above normal — the most anomalous polar heat event in recorded history. This episode breaks down the full chain of events: what caused it, what it destroyed, and what it signals about the future of our climate system. What this episode covers: How a chain of tropical cyclones near Madagascar, Indonesia, and northwest Australia triggered a cascade of atmospheric events thousands of miles away The role of a misbehaving jet stream and a blocking high-pressure system that funneled tropical heat straight onto the Antarctic plateau Why clouds in this event acted as a blanket rather than a shade — and how that amplified the warming The collapse of the Conger Ice Shelf (≈1,200 km²) and what ice shelf loss means for glaciers and long-term sea level rise The 2022 record-low Antarctic sea ice and the feedback loops that carried the damage into 2023 and 2024 What 54 scientists from 14 countries concluded about climate change's role — and the hard limits of our current climate models Why Antarctica gaining ice mass in 2022 was not the good news some headlines made it out to be Key facts: Concordia Research Station hit −9.4°C on March 18, 2022 — obliterating the previous March record by 18°C The affected area covered roughly 3.3 million km², comparable in size to India Climate change made the event approximately 2°C warmer than it otherwise would have been Under high-emission scenarios, events like this could become dramatically more frequent and 5–6°C warmer still by end of century Further reading: The Extraordinary March 2022 East Antarctica "Heat" Wave — Part I: Meteorological drivers and temperature records.

Journal of Climate, January 9, 2024. Both papers are open access and are the product of 54 scientists from 14 countries. Note: This is an AI-generated documentary-style episode.

    Weather Decoded: The Supercomputer Forecast & The Unsung Heroes Episode Description:

    Step into the invisible world of weather forecasting! This episode rips open the hood on the mind-boggling computational science behind your daily weather app. We'll meet the global forecast models – from America's GFS to Europe's gold standard ECMWF – and uncover their strengths, spectacular failures (like the "GFScane"), and why they often disagree. Discover the power of ensemble forecasts, the magic of "spaghetti plots," and how a free tool like Windy.com puts professional-grade data at your fingertips. Finally, we'll explore the rise of AI in weather prediction and the irreplaceable role of human meteorologists as "model whisperers" in a world of ever-improving technology.
