We've finally gone and done it...we're starting to create some GWG branded merchandise to sell. We're starting with an awesome tumbler and a couple of t-shirts. Our goal is to expand into more as we get our name out there. Help us out by purchasing something today!


So we're pretty pumped about this...most of the effort is in places where no one will ever see (protecting data, security, authentication, authorization, data acquisition, analytics, etc... boring computer crap) this marks an exciting day for us!

Those with a keen eye and attention to detail may notice a certain link on our website is back up and running! We've been focused hard on our infrastructure to make What APPened start to become a reality! While it's a humble beginning, and likely full of bugs, our GWG radar viewer is back! Check it out!


April 3, 2024 is our one-year anniversary. But why only celebrate one day, when you can celebrate for one whole month?

GWG plans to share special discounts, product changes, and new offerings throughout the month of April. Curious? Read on!

  • April 3-10: Timelines© price changes and product discount
  • April 11-17: Release of the GWG WhatAPPened© live radar viewer
  • April 18-24: Additional GWG WhatAPPened© offerings, including personalized account settings and subscription services
  • April 25: GWG Merchandise Store Opens


We have some big announcements coming up for our 1-year anniversary! One exciting one is changes to pricing. For our GWG Timelines reports, personal-use (if you are the property owner) will now be only $49! For commercial use (anyone using our reports to generate revenue), our reports will stay at their competitive price of $59.



A week ago, those with keen eyes may remember I posted a map (top left) I'm posting the same map (bottom right) showing this blocking pattern that's STILL sticking around. I haven't seen blocking this dominant since the Chiefs won the Super Bowl! GWG can help navigate these complex forecast patterns with our new FREE pilot program (we still have a few spots left). Contact us here to learn more!

GWG is excited to announce GWG Timelines, with a planned beta release the week of 4/17! If you're interested in testing, please contact us (with the link, replying to this post or shoot us an email at This exciting new product will offer a twist on historical impacts of weather (initially hail) over locations you care about. Focusing on a visual representation of these events and removing traditional tables full of numbers, GWG Timelines will illustrate the importance of recurring events, the duration of these events, and when coupled with a GWG One-page report, estimate the full range of hail sizes that impacted a location. This emphasis on not just a single hail size, but instead a number of how many different size hail stones impacted property, we believe, will give the most accurate estimation of damage caused by hail offered today.

Thank you again to all of our supporters and individuals who continue to give us valued feedback and business making this new venture possible! We look forward everyday to helping you navigate the dynamic waters of meteorology! 



We're open for business! GWG is happy to announce we're officially open. Please head over to and check out what we can offer, or just say hey! Thank you everyone who had a hand in making this possible.
