Storm Tracks / Included in Pro

Follow a nor’easter
through every model.

Storm Tracks maps where each model takes a developing low: the GEFS and Euro ensembles, plus the four most recent runs of GFS, GFS AI, Euro, Euro AI and HRRR. Step through the forecast to see where the paths agree, where they split and how deep the low gets.

More paths in agreement means more model support, not a probability. Rain, snow, wind and coastal flooding are not part of the tracks.

Storm Tracks / September 2026Archived capture

Captured September 24, 2026. Each frame steps the forecast from September 23 to September 30.

Nine-month outlook

Winter is already
on your mind.

See temperature and precipitation by region and month, nine months ahead. Open a cell for model agreement, confidence and reasoning, then follow the pattern into four-week and two-week outlooks.

Regional monthly guidance, with confidence that reflects the lead time. It does not predict a storm at your address nine months away.

Soundings

There’s a whole
atmosphere up there.

Open a Skew-T and hodograph with a plain-language read of the storm ingredients. Step through forecast hours at the same point.

Available on supported WDS-rendered GFS and HRRR maps. Radar soundings use HRRR guidance.

Your station / Your microclimate

What makes your
backyard different?

Connect your station for records, storm recaps and a microclimate profile. Compare overnight lows, afternoon highs and rainfall with an official reference you choose.

Requires a compatible station and about two weeks of quality-checked readings. Reference distance and terrain matter.

3D radar

Stand the storm up.

Follow observed radar into the forecast, with lightning and warnings alongside. On the web, rotate a storm in 3D or cut a vertical slice through it.

Future frames use HRRR model guidance. 3D requires a supported web browser.
