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.

Join storm chaser Gabriel Harbor and Coach Trey Greenwood as they break down the rare atmospheric ingredients, surprising dry line dynamics, and critical forecasting lessons from this historic event, so you'll know exactly what signs to watch for the next time severe weather threatens an unlikely location. 00:00 Arizona Tornado Outbreak Overview 01:15 Rare Ingredients Behind Oct 5-6 Event 02:21 Phoenix Supercells & Dry Line Dynamics 04:30 Early Morning Tornado Threat on Oct 6 06:09 Low CAPE Tornadoes: Shear & Dynamics 07:24 Forecasting Signs for Desert Southwest 08:44 Trey's Personal Storm Chasing Story On October 5th and 6th, 2010, Arizona experienced the largest tornado outbreak ever recorded west of the Rocky Mountains — an event that shattered every assumption about where significant severe weather can occur. In this episode of the Storm Chaser Coaching podcast, host Gabriel Harbor sits down with meteorologist and storm chaser Trey Greenwood to unpack the extraordinary atmospheric ingredients that converged over the Desert Southwest, producing long-tracked tornadoes, baseball-sized hail, and powerful supercells in a region most people associate with dry heat and saguaro cacti, not tornadoes. The conversation dives deep into the rare confluence of factors that made this outbreak possible: a massive closed low and trough positioned over the West Coast, anomalously strong instability for early October, remnant monsoon moisture pushing dew points into the 60s across central Arizona, and a Plains-style dry line that developed along the Phoenix metro area. Trey explains how these classic severe weather boundaries aren't limited to Tornado Alley — they can happen anywhere when the right dynamics align. The discussion also explores how storms produced significant tornadoes during the early morning hours of October 6th despite minimal diurnal heating, how orographic forcing from Arizona's complex terrain played a crucial role in storm development, and how wind shear exceeding 70 knots compensated for modest CAPE values of only 500 joules per kilogram. Trey also shares key forecasting hallmarks that meteorologists and storm chasers should watch for to identify potential Desert Southwest severe weather events in the future, along with a personal story about living through this historic outbreak firsthand. Whether you're a seasoned chaser, a weather enthusiast, or a forecaster looking to expand your understanding of severe weather in unconventional locations, this deep dive offers valuable insights into the science of tornadoes where you'd least expect them.

In this episode, Coach Trey Greenwood breaks down the wild meteorology behind the Parkersburg-New Hartford tornado, giving you the forecasting insights and radar-reading tricks you need to spot the next violent, long-track supercell before it strikes. 00:00 Intro: Parkersburg EF5 Tornado 00:47 Warm Front Sets Up Long-Track EF5 3:15 Supercell Anchoring to a Boundary 4:41 Descending Reflectivity Cores Explained 7:16 Gravity Waves & Mesocyclone Strength 9:26 Shear Profile Behind an Hour-Long Track Tornado On May 25, 2008, a violent EF5 tornado tore a 40+ mile path through Parkersburg and New Hartford, Iowa, producing catastrophic EF4 and EF5 damage along a track that would become one of the most studied long-track tornado events in Midwest severe weather history. In this episode of the Storm Chaser Coaching Podcast, host Gabriel Harbor sits down with Coach Trey Greenwood to break down the complex meteorology behind this historic tornado outbreak. Trey dives deep into the unusual surface pattern that fueled the event, including a rare north-south oriented warm front that defied typical mid-latitude cyclone structure and helped storms remain tornadic for an extended period. The conversation covers what forecasters and storm chasers should watch for when a supercell anchors to a boundary, and how that anchoring triggers rapid intensification of the low-level mesocyclone. The discussion also explores cutting-edge radar science, including descending reflectivity cores (DRCs) — a key signature researchers like Chris Broyles are studying as a precursor to tornado genesis in violent tornado cases. Trey explains how 3D radar analysis can reveal these subtle signs before a tornado forms or intensifies. Rounding out the episode, Trey unpacks the role of non-convective gravity waves in enhancing mesocyclone strength, drawing on satellite and radar evidence from the Parkersburg storm, and explains how the wind profile's shear structure — reminiscent of the "Forever Meso Hodograph" — allowed this tornado to remain on the ground for over an hour. Essential listening for storm chasers, meteorology students, and severe weather forecasters looking to sharpen their tornado forecasting and nowcasting skills.

In this episode, Gabe and Trey break down exactly which models to trust at each stage of the forecast timeline, so you can stop second-guessing your setups and start chasing with real confidence. 00:00 Intro: The Model Mistake Explained 01:12 Deterministic Models & Their Risks 02:52 Using Ensemble Models 3-4 Days Out 05:15 When Short-Range Models Like NAM Help 06:09 Why Comparing Multiple Models Matters 07:49 Key Atmospheric Features to Analyze 09:26 Final Takeaways for Better Forecasts Severe weather forecasting hinges on knowing which weather models to trust and when to trust them — and that's exactly what this episode of the Storm Chaser Coaching Podcast tackles. Host Gabriel Harbor sits down with Lead Coach Trey Greenwood to break down the forecast timeline model by model, from long-range deterministic models to short-range convection-allowing models used the morning of an event. The conversation starts by defining deterministic models versus ensemble models, and why relying on a single deterministic run (like the GFS or European Model) seven to nine days out can lead you dangerously astray. Trey explains how ensemble models average out multiple model runs to smooth over the noise and give forecasters a clearer picture of the general pattern three to five days before a potential severe weather setup. As the timeline narrows, the discussion shifts to short-range models like the NAM and other convection-allowing models such as the HRRR and 3km NAM, which become far more valuable one to two days out or on the morning of an event. Trey also covers why comparing multiple models — rather than fixating on just one — is critical for building forecast confidence, using real examples of model disagreement on surface low placement and moisture return. Finally, the episode dives into the specific atmospheric features storm chasers should analyze across model levels, including the 500mb pattern, surface dew points, shortwaves, and low-level jet dynamics. Whether you're a beginner storm chaser or a seasoned forecaster, this episode delivers a practical framework for using weather models correctly at every stage of the forecast process — helping you avoid the common model mistakes that wreck severe weather forecasts.

In this episode, Gabe and Trey break down exactly how to spot convective initiation early, read echo tops like a pro, and know which storms are worth chasing before they even show up on radar. 00:00 Intro: The Convective Initiation Moment 01:39 Earliest Clues Before Storms Fire 03:00 Reflectivity Blips Explained 04:06 Echo Tops for Diagnosing Storms 05:30 Why Some Storms Die, Others Explode 07:30 Echo Tops Limitations & Mistakes Every storm chaser knows the feeling: you've forecasted the setup, driven hundreds of miles to your target, and the sky is primed — but nothing has fired yet. That's why understanding convective initiation is one of the most important skills in storm chasing. In this episode of the Storm Chaser Coaching Podcast, host Gabriel Harbor and Lead Coach Trey Greenwood break down exactly how to use radar to catch storm development at its earliest stages. They start with the clues that appear before anything shows up on radar — boundaries, fine lines of reflectivity, and bubbling cumulus fields that signal an atmosphere ready to explode. From there, they explain the first true radar signature of a developing storm: the blip, a small pocket of reflectivity that marks the beginning of precipitation aloft. The conversation moves into echo tops and enhanced echo tops, key radar products for estimating cloud top heights and identifying which developing storms have the best chance of becoming severe. Trey explains the science behind why some updrafts collapse under a stubborn cap or dry air aloft, while others cluster together, resist entrainment, and blossom into dominant supercells — often with an assist from an approaching shortwave. Rounding out the discussion, Trey covers the common mistakes and limitations chasers run into when relying on echo tops, especially when storms are close to the radar site, and why pairing radar with satellite imagery gives you the clearest picture of a storm's true potential. Whether you're new to storm chasing or refining your forecast-day strategy, this episode delivers practical, field-tested techniques for identifying convective initiation, reading radar blips, and targeting the storms most likely to become the day's dominant supercell.

In this episode, you'll learn how to analyze surface maps, interpret Skew-T soundings and hodographs, and identify the boundaries that separate a good chase from a life-changing one. 00:00 Podcast Intro 00:53 Identifying Surface Lows on a Weather Map 01:33 Reading Cold Fronts, Warm Fronts & Dry Lines 03:49 Why Boundaries Drive Storm Initiation & Tornadoes 05:08 Skew-T Soundings: Instability & Capping Explained 07:05 Hodographs & Tornado Potential In this episode of the Storm Chaser Coaching podcast, host Gabriel Harbor and Coach Trey Greenwood break down the final piece of the storm chasing forecast puzzle: surface analysis and atmospheric soundings. Together, they walk through exactly how to read a weather map, interpret upper-air data, and identify the conditions that separate a tornadic supercell from an ordinary thunderstorm. The conversation begins with surface lows — how to locate them using isobar analysis and counterclockwise wind circulation — then moves into the art of identifying weather boundaries. Cold fronts, warm fronts, and dry lines are not found by looking at a single clue. Trey explains that confident boundary placement requires a confluence of signals: wind shifts, temperature gradients, moisture gradients, and pressure tongues on a fully analyzed surface map. The dry line in particular demands attention to dew point contrasts, with high moisture on the eastern side and drastically drier air to the west. From there, the episode dives into why boundaries matter so much for storm initiation and tornado potential. Surface convergence along boundaries focuses lift, while the enhanced low-level wind shear and vorticity along boundary zones gives supercells the raw spin they need to produce significant tornadoes. Storms that track parallel to a boundary — rather than crossing it — stay in the most favorable thermodynamic environment and maintain elevated tornado potential. The final two topics cover the Skew-T sounding and the hodograph. The Skew-T reveals atmospheric instability through the relationship between the temperature profile and parcel trace, while capping inversions — identified by a warm nose in the low levels — help forecasters anticipate explosive storm development later in the day. The hodograph, meanwhile, maps wind shear through the atmosphere: a sickle-shaped or meat hook curve in the low levels is a hallmark signature of environments favorable for tornadic supercells.
