Recorded weather · gaps are marked. Coverage begins with recording activation.

Live sources keep independent clocks.

Replay coverage and interpretation

Rolling target: 24 hours; cells: six hours. Radar: NOAA MRMS national overview, 8-minute tolerance. Satellite: original GOES GeoColor day/night picture, hourly sampling, 75-minute tolerance. No interpolation or latest-image fallback. Warning and source checks retain their own clocks. “Recorded by” is collector acquisition evidence, not exact browser publication history.

Current GLM density, velocity and specialist layers are hidden during replay. Snow uses retained footprint metadata with unverified pixel time. Forecast uses one pinned issuance/run and exact valid time.

No observed replay frame displayed.

WPC’s heavy snow and icing discussion · captured source context

Washington Cascades Days 1-3

A couple of cold fronts will bring periods of snow to the higher Cascades this morning and again late Monday into Tuesday, mainly above 5000ft. This will affect Washington Pass/SR-20 (5476ft) which is still open. The probability of at least 4 inches of snow tomorrow into Tuesday is about 10-20% before milder air changes the snow over to rain there by Tuesday afternoon.
