CartoSky: Weather Model Maps

CartoSky puts ECMWF, GFS, HRRR, ICON and ensemble weather model maps on a fast interactive map, with meteograms, radar, official forecast products, and Skew-T soundings alongside. Switch models, scrub forecast hours, and inspect derived products instead of paging through static images. Every map shows its run and valid time, so you always know how fresh the data is and where it came from. MODEL CATALOG • Global models: ECMWF, GFS, ICON, UKMET, GDPS, plus AI models AIFS and AIGFS • High resolution: HRRR, RRFS, NBM, RDPS, HRDPS • Ensembles: EPS, GEFS, AIFS ENS, AIGEFS, CMCE, REFS, WeatherNext 3, with means, percentiles, probabilities and individual members • Extended range and seasonal: ECMWF Weeklies, GEFS Extended, CFSv2, CanSIPS, ECMWF SEAS5 • Observed: NEXRAD and MRMS radar, GOES satellite, current analysis, sea surface temperature, NOHRSC snowfall, SWPC aurora • Outlooks and hazards: SPC, WPC and CPC outlooks, winter storm severity, NWS watches and warnings • Regional and global coverage, with resolution varying by model DERIVED PRODUCTS • Temperature and height anomalies against an ERA5 climatology baseline • Kuchera-ratio and 10:1 snowfall, precipitation totals over 6, 12 and 24 hour windows • Precipitation type, simulated radar, CAPE, wind gusts, smoke, lightning • Ensemble spread, member plumes and probability-of-exceedance maps TOOLS BEYOND THE MAP • Meteograms: multi-model and ensemble time series for any point, with spread and run-to-run changes • Compare: two models or runs with synchronized maps and forecast times, with a Difference view • Skew-T soundings from model data • Point Desk: point forecasts with model trends and ensemble statistics • Event Desk: follow upcoming storms with model agreement and hazard summaries • Climate and Atlas: teleconnection indices, MJO and ENSO patterns, and analog years • Forecast: a location-first daily and hourly view SHARE YOUR ANALYSIS Capture screenshots, animated GIFs and annotated maps with run and valid-time stamps baked in. Share links let others reopen your exact weather view. BUILT FOR THE PHONE TOO Touch-friendly controls, and favorites and preferences that sync across your devices when you sign in. WHO IT IS FOR Weather enthusiasts tracking storms and comparing guidance, storm chasers, and forecasters who want an interactive model analysis workspace. Core access is free. Data sources include NOAA, ECMWF open data, Environment and Climate Change Canada, and Open-Meteo. Available products, ensemble statistics, coverage and forecast ranges vary by model.
