Global Weather Data Gaps Impact Forecast Accuracy
US · Published May 1, 2026
Missing weather data is compromising the accuracy of weather forecasts, especially during severe weather seasons.
Changes in the National Weather Service's weather balloon launch schedules have led to fewer data inputs for critical forecast models.
Climate change is exacerbating the impact of data gaps by increasing the intensity and frequency of extreme weather events.
Data gaps affect severe weather prediction accuracy
Meteorologists are raising serious concerns about how missing weather data is affecting the accuracy of forecasts, particularly when it comes to predicting severe weather. Changes in the National Weather Service's weather balloon launch schedules have resulted in fewer data inputs, which are essential for weather models like GFS, Euro, and NAM. Without consistent data, these forecasts become unreliable, posing risks to public safety and emergency response efforts. This issue is made worse by climate change, which is increasing the frequency and intensity of extreme weather events globally.
