This is the best, value for money, tour group on the Plains - total tour costs are only $1,775 US$ <tour deposit of $1,325 plus 6 nights hotels on the road for $450 average>, for a full 7 days chasing on the road - a unique collaborative approach run on a non-profit basis.

Be part of a group of like-minded people joining together to pursue and capture the "whole severe storm experience" - tornadoes, supercells, lightning and severe weather of all kinds.

StormGroup Chasers has had an impressive track record in the past five years, with 40 tornadoes witnessed, including some major EF5 tornadoes.  We have been on most of the major outbreaks - including Joplin, La Crosse, Kingfisher, Ault, Moore, Carney/Shawnee, Hutchinson and El Reno.

But it's not just about the tornadoes - in 2015, despite the quiet season, we chased severe-warned storms on 31 of the 44 days on the road, saw 8 tornadoes and some other amazing sights, brought home some great photogaphy, and visited some unique and interesting places - was another great season.

Using only one vehicle, with 4 guests on each tour, this is a very nimble and flexible approach to storm chasing - no one is packed into large vans, and there are no large groups to herd through meals and rest stops.  We eat in unique local restaurants where possible, usually have picnic lunches with healthy food in parks/scenic areas - and lots of time to target all severe weather, while still maintaining a "human" personal approach to each guest's needs on the long driving days.

Then come join us in 2017 - or maybe convince someone else that they should have this unique experience - don't miss the opportunity to chase with a safe and proven team.

The Chase

Whether you know a lot about chasing severe storms or are just beginning to explore Mother Nature's fury, StormGroup Chasers will offer you a unique collaborative experience where the key words are communication, learning, photography and fun.

With access to all of the weather software and forecasting sites and models, you’ll be able to take part in the daily decision-making about chase targets, while learning about what drives severe storms, based on over ten years of chasing, severe storm forecasting and a life-time interest in the weather.

Each tour is seven days on the road using one chase vehicle, allowing flexibility of movement to make the best use of our chase days. With two drivers and four passengers, everyone has a window seat. While there is never any guarantee of tornadoes, StormGroup Chasers will chase all available storms for the best "severe storm experience".

Safety is paramount, but being able to photograph the experience is also a primary objective. From the power and beauty of a tornado or supercell, to a striking cloud formation, or a beautiful sunset, or a scene encountered on route, each day will take into account our shared love of photography.

Tour Leadership

Your tour will be led by myself, Peter Wharton, as tour organiser and lead forecaster.  I started storm chasing in 2002 after a lifelong interest in severe weather.  My earliest memory is standing in my crib and watching a major lightning display one night in London - childhood imprinting for severe weather!

I've personally witnessed over 70 tornadoes in my years of chasing. An especially photogenic experience was the classic Campo, Colorado EF2 tornado on May 31st, 2010 - this was a "chaser's dream tornado" - one that chasers wait years to see, and then talk about forever!  In 2011, we were within a few miles of the destructive Joplin, Missouri tornado - a sobering experience, reminding us of the devastating impact of severe weather on local communities.  In 2012, we witnessed 7 tornadoes one magic afternoon/evening at La Crosse, Kansas - that evening's chase ended with a huge cone tornado just a mile away, popping out of the gloom only when backlit by intense CG lighting.  The 2013 tours included huge wedge tornadoes at Carney & El Reno, OK and Bennington, KS - unfortunately with tragic outcomes at El Reno, giving a pointed reminder of the need to be ever vigilant about safe chasing practices.

Despite all these dramatic events, the experience of closing in on a massive rotating "spaceship" supercell never ceases to amaze me - I really enjoy the challenge of targeting severe weather, rolling along on a superb road trip with great people, and doing my utmost to deliver the best possible chasing experience.

Malcolm Stewart, from Sydney, Australia, returns for a fifth season on the Great Plains.  He will be my co-driver on Tours 1 & 2 for the 2016 season.  Now retired after a long career as an airline pilot, his professional interaction with the atmosphere and weather has transitioned to a keen interest in the prediction and tracking of supercell thunderstorms in the Mid-West. "The dramatic Carney, OK wedge tornado in 2013, and the classic Canadian, TX cone tornado in 2015 have been just some of the highlights of my experience chasing with StormGroup Chasers."

Brad Matter returns for a 6th season, and will be my co-driver on Tours 3 & 4 in 2016. He calls Canada home after driving for UPS in California for 35 years.  Having chased for 3 years with other tours, he was driving in 2012 when we encountered 7 tornadoes after sundown near La Crosse, Kansas, and in 2013 was driving on our chase of the huge El Reno tornado, and in 2015 was there for some amazing mothership supercells in NE Kansas.  Brad has a great love of the outdoors, a passion for severe storms and a well developed sense of humour - including his keen appreciation of English humour.

Rick Young has been chasing with me for 7 years, and will be my co-driver for Tour 5 in 2016.  He comes from a high-tech background and resides in Canada, spending winters in Florida.  His background supports his fascination and passion for severe weather.  He was with me for the "perfect tornado" in Campo. CO; a massive stationary wedge tornado near Bennington, KS; the tragic El Reno eruption; and many, many more. "Peter's small group approach gives everyone an opportunity to be involved, communicate, ask questions and learn".

Lisa Worthen, from Texarkana, TX, will be co-driving on Tour 6 in 2016.  She has driven for many years - her first job driving a school bus for 13 years, then operating heavy equipment for a school district, then driving an 18 wheeler with her husband on the road for 4 years - accumulating about a quarter of a million safe miles. "I was always terrified of any kind of storm.  At the first flash of lightning I'd be hiding in the closet or in the bath with a mattress over my head!  My daughter suggested that we go storm chasing in May of 2010 - yup, Campo - the storm chaser dream.  Needless to say, I was hooked.  I met Peter that year, and I've been chasing with him ever since". When Lisa isn't storm chasing, she owns & operates two health food stores and a yarn shop.

Consider joining us for a personalised and flexible approach to experiencing the annual drama on the Plains - a unique collaborative chasing opportunity.
