This is the most intuitive, yet comprehensive weather app I’ve used. Fantastic radar, superior extended forecast modeling, and finally, an app with solid wind forecasting.

FAQ

What weather sources does VortiCast use?

VortiCast uses National Weather Service data for days 1-7. For days 8-14, it taps into the ECMWF ensemble (EPS) and GEFS, providing a range of possible outcomes rather than a single prediction.

How does VortiCast's radar forecast work?

The radar feature plays 18 hours into the future, blending live MRMS radar with NOAA's HRRR model. This provides physically grounded guidance for storm movement, not just a cartoon loop.

Can I compare different weather models in VortiCast?

Yes, VortiCast's 'Compare Models' feature allows you to see NWS, GFS, and ECMWF data side-by-side, helping you identify areas of agreement and divergence.

What is 'Forecast Confidence' in VortiCast?

Forecast Confidence indicates how settled the weather outlook is, day by day, by analyzing the spread across ensemble models. It highlights whether temperature or precipitation forecasts are less certain.

What features are included in VortiCast Pro?

VortiCast Pro unlocks the Radar Forecast, Forecast Confidence, Compare Models, extended hourly graphs, advanced satellite bands, GLM lightning, surface observations, SPC outlooks, and wind forecast maps.

How much does VortiCast Pro cost?

VortiCast Pro is available for $5.99 per month or $39.99 per year. New subscribers receive a 7-day free trial.

What devices does VortiCast support?

Currently, VortiCast is supported on iPhones. The app is rated for ages 4 and up.

How often is VortiCast updated?
