Today, we are unveiling StormNet 4.5. This update includes a new interface, new radar features, and a new StormNet model capability.

After several breakthroughs and tons of R+D, we are excited to announce that we have developed a SOTA short-range weather prediction model.

Real-time case study from yesterday's Oklahoma severe thunderstorms

Comparing StormNet's radar forecast members yesterday against HRRR and REFS. MRMS is actual radar (ground truth).

These are at 3-9hr lead-times, valid around storm initiation and around storm maturity.

Today’s tornado threat didn’t exactly materialize across Oklahoma. Convective mode ended up being very messy.

I did find it interesting that the StormNet radar forecasts, even from 10-12 hours out, were very messy which ended up verifying.

HRRR, for comparison, was more ate today didn’t include changes to the daily severe weather probabilistic forecasts, though upgrades to that component are in the works.

There are several other new features and enhancements as well that are now live on the website and on the mobile app (iOS and Android).

Our research efforts continue and we have a ton of projects in the works for the next few months.

The premium subscription which we are adding soon will help support our research efforts while we keep the most critical info (short range data & daily forecasts) free.
