About Flash Weather · Canton, Georgia
Built by meteorologists who used to issue the warnings.
Flash Weather is a weather-intelligence company: 15+ proprietary prediction products and over 100 API parameters on a 1×1 km grid, refreshed as often as every 2 minutes, built by meteorologists who spent their careers at NOAA's National Weather Service deciding when to warn people.

The origin
Flash started with a storm that arrived before the warning did.
Flash Weather was founded by Jason Deese after a personal experience with a storm. He had spent twenty years at NOAA's National Weather Service issuing the warnings, latterly as Chief Meteorologist at Atlanta Hartsfield-Jackson International Airport; the company he started exists to put that forecast in the hands of the person who has to make the call — before the first strike, not after it.
That is why Flash predicts rather than detects. FirstStrike forecasts where lightning will strike up to 60 minutes ahead on 1×1 km cells, refreshed every 2 minutes; Predictive Hail predicts hail up to 55 minutes before it reaches a site. No sensors required for the forecast — software only, delivered through the Command Center, the mobile app, the API and Skye, Flash Weather's AI weather agent.

THE STORM THAT STARTED IT
The warning arrived after the storm did. Flash exists to reverse that order.
The people on the technical pages
Two meteorologists put their names to the numbers.
Every figure on the site is reviewed by a forecaster who used to issue the warnings. These are the two the technical pages name.

What we believe
Three principles decide what Flash builds — and what it refuses to claim.
They are the reason every number on this site carries a qualifier, and the reason the forecast ends up in your calendar rather than on another dashboard.
WHAT WE BELIEVE
A forecast is a promise about a place. Say which place, and say how sure you are.
Predict, don't detect.
A detector tells you a strike has already happened. A prediction tells you which 1×1 km cell is about to take one, up to 60 minutes ahead. Everything Flash builds starts from the second, because that is the one a coach, a foreman or a superintendent can act on.
Publish the method.
Every accuracy figure we quote comes with its window: up to 99.6% lightning prediction accuracy on the one-hour window. The accuracy method page shows how the number is computed and when it was last refreshed.
Act in the customer's tools.
A forecast is only useful when it changes a decision. Skye answers in plain language and acts in the calendar, ERP or CRM you already run — Google Calendar, Procore, HubSpot, NetSuite — with a human confirming any change to a schedule or a record.
