Weather Models
Curated collection of weather forecast models from NOAA, ECMWF, and Environment Canada. Each shows a different perspective on what the atmosphere will do.
Global Ensemble Models
GEFS
NOAA NCEP
NOAA's 31-member global ensemble. Spaghetti plots show forecast uncertainty by overlaying all members. Best for medium-range pattern recognition and tropical cyclone tracking.
ECMWF EPS
European Centre for Medium-Range Weather Forecasts
The European 51-member ensemble — the gold standard for medium-range forecasting. Free OpenData access provides reduced resolution but full ensemble spread.
GEPS
Environment and Climate Change Canada
Canada's global ensemble forecast system. A useful third opinion alongside GEFS and ECMWF EPS for assessing forecast confidence.
Global Deterministic Models
GFS
NOAA NCEP
The single "best guess" companion to GEFS. Sharper resolution, faster updates, no ensemble spread. The default reference for general weather forecasting.
ECMWF
European Centre for Medium-Range Weather Forecasts
The European model — widely considered the most accurate global forecast model. Free OpenData access provides reduced-resolution products.
GDPS
Environment and Climate Change Canada
Canada's flagship global model. Fast updates, good North American coverage, useful third comparison alongside GFS and ECMWF.
Regional / High-Resolution Models
HRRR
NOAA NCEP
High-resolution CONUS model used by storm chasers and severe weather forecasters. Hourly updates with hour-by-hour precision for the next 18 hours.
NAM
NOAA NCEP
Higher-resolution North American model than GFS. Better for next 3-4 days of detailed weather, severe weather setups, and frontal passages.
NBM
NOAA
A consensus forecast blending GFS, NAM, HRRR, ECMWF, and others. Produces a single best-of forecast — what most consumer apps actually display.
Hurricane Models
HWRF
NOAA NCEP
Specialized hurricane model that spins up for each active named storm. Very high resolution storm core, excellent for intensity and track prediction.
HMON
NOAA NCEP
NOAA's second hurricane model. Different physics scheme than HWRF — running both gives valuable storm forecast uncertainty.
