By the end of this episode, you'll know how to read the landscape before it reads you, so you can chase smarter, stay safer, and avoid the costly mistakes that catch even experienced chasers off guard. 00:00 Storm Chasing Dangers Beyond the Tornado 00:55 Visibility: Critical for Chase Safety 01:43 Chasing in Forested and Hilly Terrain 03:40 Gridded Road Networks for Supercells 04:34 Roadway Hazards and Chaser Safety 06:12 Hydroplaning Risks on Wet Paved Roads 07:12 Car Damage: Lessons from 2019 Chase 09:47 Final Safety Tips In this episode of the Storm Chaser Coaching Podcast, host Gabriel Harbor sits down with Coach Trey Greenwood to break down why the tornado itself is rarely the most dangerous part of storm chasing. Instead, the real threats come from terrain, visibility limitations, and poor road decisions that can quietly turn a routine intercept into a disaster. The conversation kicks off with a deep dive into why visibility is one of the most critical safety concepts every storm chaser needs to master. Coach Trey explains how hills, heavy rain, and terrain features can block your view of evolving storm structure, forcing you to rely on radar alone — which is only an estimate of what's happening in real time. When chasing in heavily forested or hilly regions like the Southeast, Central Texas, or the Northeast, the strategy shifts dramatically. Rather than attempting aggressive close-range intercepts, chasers should scout downstream locations, let the storm come to them, and always maintain multiple escape routes. The episode then explores what makes gridded road networks so valuable for supercell chasing in places like Southwest Kansas and West Texas, where roads run every mile north-south and east-west. But not all roads are created equal — dirt roads can quickly turn to mud after heavy rainfall, and chaser convergence can create dangerous traffic conditions. A follow-up discussion on hydroplaning highlights how even paved roads become hazardous when chasers fail to adjust their speed in wet conditions. The standout moment comes when Coach Trey shares a personal story from 2019 near Tahoka, Texas, where a tornadic supercell, a poorly planned escape route, and an unseen rut on a dark dirt road led to a cracked radiator and a scramble for cover from baseball-sized hail. The lesson is clear: always have a plan for where you're going next, study your maps, and never assume a road is passable just because you're in West Texas. The episode wraps with a reminder that vehicles are replaceable, but lives are not — and that proactive planning is the most powerful tool a storm chaser can carry.

In this episode, Coach Trey Greenwood breaks down why storm interactions aren't just important but essential — giving you the knowledge to recognize when messy equals dangerous, and the confidence to hold your ground when everyone else is driving home. 00:00 Intro: Storm Interactions & Supercells 00:30 Why Storm Interactions Are Critical 01:47 Wind Shear & Dry Air Effects on Storms 02:30 ECAPE: Measuring Dry Air Impact 04:37 Storm Clustering & Survival 05:35 Handling Messy Storm Mode Most storm chasers are trained to hunt for clean, isolated supercells — but what if that instinct is actually costing you tornadoes? In this episode of the Storm Chaser Coaching Podcast, host Gabriel Harbor sits down with Coach Trey Greenwood to unpack why storm interactions aren't just important for supercell development — they're often essential. The conversation kicks off with a deep dive into why isolated updrafts frequently fail to survive on their own. Trey explains that the very environmental factors that allow storms to become robust supercells — strong wind shear and dry air — can also tear lone updrafts apart before they ever mature. Wind shear shreds isolated storms, while dry air chokes off updrafts by diluting the instability they ingest as they climb. The solution? Multiple updrafts clustering together to act as a unified, resilient force against hostile atmospheric conditions. The episode also explores ECAPE (Entrainment CAPE), a cutting-edge forecasting parameter that measures how much dry air aloft actually reduces the instability a storm experiences — potentially cutting 4,000 j/kg of CAPE down to 1,000. Trey then walks through the real-world implications: early storm clustering may look messy and disorganized, but in environments with strong low-level and deep-layer wind shear, that chaos is exactly what storms need to survive and mature into dominant supercells. If you've ever felt disappointed by a blobby, disorganized mess on radar, this episode will change how you read the sky.

In this episode of the Storm Chaser Coaching podcast, you'll learn how to read the 500 millibar map like a pro — decoding troughs, ridges, geopotential heights, and trough tilt to spot severe weather setups before they unfold. 00:00 The 500mb Map & Big-Picture Pattern 00:49 Why Forecasters Start at 500mb 01:24 Geopotential Height Contours 02:33 How Troughs Appear on the 500mb Map 03:43 Trough Exit Region & Severe Weather 04:46 Trough Tilt & Severe Weather In this episode of the Storm Chaser Coaching podcast, host Gabriel Harbor sits down with Coach Trey Greenwood to break down one of the most essential tools in severe weather forecasting: the 500 millibar map. If you've ever wondered why forecasters always start here when evaluating a severe weather setup, this conversation walks you through exactly why. Trey explains that the 500mb level reveals the overall atmospheric pattern, giving forecasters a snapshot of troughs, ridges, and the general flow that dictates what happens closer to the surface. The discussion covers geopotential height contours — what they represent, how they differ from surface pressure analysis, and why falling heights signal rising motion that can fuel thunderstorm development. You'll learn how to identify troughs and ridges on a 500mb map by spotting downward kinks in the height contours, and why troughs are the key features to watch for severe weather. Trey dives into the exit region of a trough, where rising motion is maximized, and breaks down how jet streak geometry and vorticity advection drive that upward motion. The episode wraps with a deep dive on trough tilt — the difference between negatively and positively tilted troughs, why negative tilt often means better overlap of instability, wind shear, and vorticity advection, and how a mature negatively tilted trough can signal a higher-end severe weather event. Whether you're a beginner storm chaser or refining your forecasting skills, this episode gives you a practical framework for reading the big-picture pattern.

Most storm chases aren't won when the tornado drops — they're won hours earlier when you decide where to position yourself and how to get there with time to spare. Trey explains why arriving early to your initial target is critical, giving you the flexibility to review surface observations, assess changing weather data, and adjust your position as storm initiation evolves throughout the day. The conversation covers the delicate balance of timing — arrive too late and you risk rushing, driving dangerously, and missing storms altogether; arrive too early and you may fall victim to analysis paralysis, second-guessing your forecast as every new model run and HRRR update comes in. Trey recommends arriving about an hour ahead of storm initiation as a sweet spot, giving enough time to gas up, review radar data, and reposition without overthinking your plan. Trey shares a real-world example from May 18, 2025 — the Arnett, Oklahoma tornado day — where persistent stratus clouds forced a major target adjustment from southern Kansas down to Seiling, Oklahoma, resulting in a successful chase. The episode also dives into building contingency plans ahead of time, adjusting for outflow boundaries and cloud decks on the fly, and how to honestly evaluate your chase performance afterward by reviewing radar and satellite data with a clean slate. Whether you're a seasoned storm chaser or just getting started, this episode is packed with actionable advice on target selection, chase-day timing, and post-chase analysis to make every outing a learning experience.

Join Gabriel Harbor and meteorologist Trey Greenwood as they break down the hidden storm-scale processes behind the Plainfield F5, revealing practical forecasting and chasing lessons that could help you spot the next tornado that "wasn't supposed to happen." 00:00 Plainfield F5: Tornado That Defied Odds 01:25 Why Plainfield Was Historically Unusual 01:59 Synoptic Pattern: Aug 28, 1990 Setup 02:34 High CAPE, Low Shear Tornado Setup 03:47 Storm-Scale Processes Behind the F5 05:01 Outflow Boundary Tornadogenesis Cases 06:01 Forecasting Lessons from Plainfield F5 On August 28th, 1990, a violent F5 tornado carved a devastating path through the Chicago suburbs, killing 29 people and injuring hundreds more. What makes the Plainfield tornado so extraordinary to meteorologists and storm chasers alike is that the atmospheric environment that day didn't look favorable for a violent tornado at all. With extreme instability but very limited low-level wind shear, the setup typically associated with hail and damaging winds rather than F5 tornadoes, this event defied conventional tornado forecasting logic. In this deep-dive conversation, host Gabriel Harbor sits down with meteorologist Trey Greenwood of Convective Chronicles to unpack the meteorology behind one of the most powerful tornadoes in U.S. history. They explore the large-scale synoptic pattern that day — a classic northwest flow event with an elongated trough and jet streak aloft — and examine why the high CAPE, low shear environment should have precluded significant tornadic supercells. The key lies in storm-scale processes: the Plainfield supercell generated its own outflow boundary, surged ahead of the storm, and then caught back up to it, ingesting critical low-level vorticity along that boundary to produce an EF5 tornado. Trey also draws parallels to a similar 2019 Tahoka, Texas case where the same outflow boundary tornadogenesis mechanism produced a significant EF2 tornado. The episode wraps with practical forecasting and storm chasing lessons — always watch outflow boundaries, never write off a supercell too early, and remember that extreme instability can override weak low-level shear when boundaries are in play. From the Jarrell, Texas tornado of 1997 to the Plainfield F5, history shows that when CAPE is sky-high and a boundary interacts with a supercell, the rules can go out the window.
