Weather forecasts have become more accurate
Overall perception of forecast accuracy
- Many commenters agree long-range forecasts (3–14 days) have improved versus decades ago, citing better storm tracking and temperature trends.
- Others report worsening or unreliable forecasts in specific locations (e.g., Boston, Bay Area, Southern California), especially for rain intensity, wind direction, or coastal/mountain microclimates.
- Several note that 1–2 day forecasts are usually solid, but hour-by-hour or minute-level predictions feel poor.
Hyperlocal rain & “nowcasting”
- Former Dark Sky users widely praise its minute-precise rain alerts; many feel Apple’s integration degraded accuracy.
- Complaints about apps saying “no rain” while it’s raining (or vice versa) are frequent; explanations offered include coarse spatial grids, stale model outputs, radar gaps, and microbursts.
- Some regions (e.g., Netherlands, parts of Europe) rely heavily on live rain radar rather than textual forecasts for short-term decisions like cycling.
Models, AI, and technical aspects
- Discussion of physics-based Numerical Weather Prediction vs. newer AI models (GraphCast, Pangu, ECMWF’s AIFS).
- Consensus in-thread: AI models are roughly on par or slightly better than state-of-the-art traditional models, not a dramatic leap for end users.
- Short-range “rain in X minutes” products often use radar + simple optical flow, not deep physics.
- Grid resolution and terrain complexity (mountains, urban heat islands) limit local accuracy.
Climate change and model reliability
- Some suspect climate change makes forecasts worse via more volatile weather or invalidated historical data.
- Others counter that core physics-based models remain valid; climate shifts mostly affect statistical post-processing and bias corrections, not basic forecast skill.
Human perception, probability, and media
- Commenters highlight confirmation bias: people remember the misses, not the many quiet hits.
- Misunderstanding of “chance of rain” leads to judging good probabilistic forecasts as “wrong.”
- Consumer-facing providers may inflate rain probabilities or dramatize storms due to clickbait and user expectations.
Tools, strategies, and equity
- Many recommend raw or government sources (e.g., hourly charts, radar, forecast discussions) over simplified apps.
- Local expert meteorologists are valued for interpreting models in context.
- The article’s point that poorer countries pay more (as GDP share) for worse forecasts is echoed as a serious equity issue.
