Overview
- A broad winter system is expected to bring heavy snow, sleet, and freezing rain across large parts of the United States this weekend, with alerts posted for cities including Atlanta, Boston, Dallas, New York, Philadelphia, Raleigh, and Washington, D.C.
- Earlier this week the app displayed extreme amounts — up to two feet or more in some locations — prompting viral screenshots and confusion on social media.
- As the low-pressure track becomes clearer, projected snowfall in the app has decreased in many cities, and some areas now show a wintry mix or icing instead of prolonged heavy snow.
- Apple incorporates data from the National Weather Service, The Weather Channel, and NOAA and uses Dark Sky technology, yet its presentation can reflect a single model rather than a synthesized forecast, drawing criticism from some meteorologists.
- Forecasters recommend consulting local stations and multiple sources for accumulation guidance and using Apple’s severe weather and next-hour precipitation alerts for short-term decisions.
