The Bridge

Consistently the best-verifying global model in the 3–7 day range. Runs at 00Z and 12Z.

NCEP's global workhorse — four runs daily out to 16 days, backbone of US forecast products.

Navy Global Environmental Model — tuned for marine boundary-layer physics and ocean-atmosphere coupling.

Global Ensemble Forecast System — 31 perturbed runs of GFS, four times a day, for probability and spread.

Real-time wave buoy observations along the US Pacific and Atlantic coasts, with WW3-nested forecasts.

OPC's clickable global basin viewer driven by Navy HYCOM — 0 to 72-hour current and SST forecast loops.

NOAA's interactive coastal GIS — currents, SST, sea ice, marine zones, radar, and observations on one map.

NOAA's authoritative tide and tidal-current network — predictions and live observations at every station.

CDIP / Scripps wave forecast viewer — significant height, period, direction, with California regional zoom.

The canonical operational sounding database — twice-daily RAOB observations worldwide, archived to 1973.

US radiosonde soundings plotted with severe-weather parameters overlaid — CAPE, shear, STP, lifted index.

Forecast soundings from HRRR, RAP, NAM, GFS, and HiResW at thousands of US points — hourly vertical profiles.

NBM meteograms — hourly time-series of temperature, wind, precipitation, and cloud for any US point.

SPC's operational severe-weather parameter grid — CAPE/CIN, shear, helicity, STP, supercell composite, hourly.

SPC's categorical convective outlooks — tornado, hail, and damaging-wind probabilities for Days 1–8.

Issued whenever SPC identifies a developing severe threat — the meteorologist's-eye narrative behind a watch.

Live SPC watch boxes and county-level NWS warnings on a national map with active polygons.

Visualized GEFS ensemble charts — spaghetti plots, ensemble mean, spread, and probability fields.

ECMWF's ensemble — 51 perturbed members, generally the tightest probabilistic performance of any global ensemble.

NOAA's operational hurricane model — high-resolution, movable inner nests, coupled ocean. Replaced HWRF in 2023.

AOML's multi-model viewer — HAFS operational, HAFS experimental, HWRF legacy, coupled ocean-atmosphere.
