WeatherDynamics Support
WeatherDynamics brings forecasts, radar, observations, and atmospheric analysis together in one application. Whether you're checking tomorrow's weather or examining the atmosphere in greater detail, we want the information to be understandable, timely, and scientifically transparent.
If something isn't working as expected, start with the answers below.

When reporting a problem, it helps to include:
- Your iPhone model and iOS version.
- The WeatherDynamics app version.
- The screen or feature involved.
- The location or radar station you were viewing.
- A brief explanation of what happened.
- A screenshot, if available.
Please do not include passwords, private account credentials, or other sensitive information.
Important: Severe Weather and Personal Safety
WeatherDynamics is an information and analysis application, not an official emergency-warning service.
Weather forecasts, radar observations, and alerts may be delayed, interrupted, incomplete, or unavailable. Never rely on WeatherDynamics as your only source of information when severe weather threatens.
For official warnings and safety instructions, consult the National Weather Service, local emergency management authorities, and other established warning channels.
Wireless Emergency Alerts, NOAA Weather Radio, and local emergency communications provide additional sources of information. In an emergency, call 911.
Forecasts and Current Conditions
Where does WeatherDynamics get its weather information?
WeatherDynamics uses meteorological information from government agencies and other established weather-data providers, including:
- National Weather Service forecasts, warnings, observations, and forecast discussions.
- NOAA radar, atmospheric analyses, and other weather products.
- Storm Prediction Center, Climate Prediction Center, Weather Prediction Center, and National Hurricane Center products.
- NOAA marine, buoy, and tide information where supported.
- NOAA Regional Climate Center climate records and normals.
- Upper-air observations obtained through the Iowa Environmental Mesonet.
Some products are retrieved directly by your phone, while others are prepared by WeatherDynamics-operated services.
See our Data Sources & Methodology page for more information.
Why can current conditions differ from what I see outside?
A nearby observation station measures the atmosphere at its own location, which may differ from your exact surroundings.
WeatherDynamics may also display values from NOAA gridded analyses. Those values are spatial estimates derived from meteorological data, not direct measurements at your location.
The app is designed to identify its sources so you can distinguish observations from analyzed or modeled conditions.
Why does a forecast sometimes change?
Forecasts are updated as new observations, model guidance, and forecaster assessments become available.
A change in tomorrow's forecast does not necessarily mean an earlier forecast was inaccurate. Forecast revisions and forecast verification describe different things.
Why is information marked old, delayed, or unavailable?
Weather information arrives from multiple providers, each with its own update schedule.
If new data cannot be retrieved, WeatherDynamics may continue displaying previously received information with its age indicated.
WeatherDynamics does not intentionally replace missing meteorological values with zero or present unavailable observations as verified measurements.
When information is unavailable, check its timestamp and source before relying on it.
Why do different weather sources disagree?
Weather observations, numerical models, and forecast products use different methods, resolutions, update times, and assumptions.
Disagreement is a normal part of weather prediction. Agreement between sources can be informative, but it does not automatically establish a statistically calibrated probability or confidence level.
Radar and Maps
Why does radar sometimes appear outdated?
Weather radar collects observations during scheduled scans rather than continuously.
There can be a delay between when a radar sweep is collected, when its data becomes available, and when WeatherDynamics displays it.
Check the observation timestamp rather than assuming the radar image represents conditions at the current second.
What's the difference between national radar and single-site radar?
National radar mosaics combine information from many radar systems to provide broad geographic coverage.
Single-site radar products display data collected by an individual radar. Depending on the product, these may provide greater spatial detail and additional measurements useful for storm analysis.
The two views serve different purposes and may have different observation times, spatial resolution, and coverage limitations.
Why does a storm look different on different radar products?
Reflectivity, radial velocity, and dual-polarization products describe different characteristics of radar returns.
They are not interchangeable. Radar interpretation also depends on distance, elevation angle, beam height, and the atmosphere between the radar and the target.
A radar signature alone should not be treated as proof that a tornado or another specific weather phenomenon has occurred.
What should I do if the radar or map doesn't load?
First, verify your internet connection and try reopening the affected screen or refreshing the data where that option is available.
If the problem continues, close and reopen WeatherDynamics.
Some map and radar products are served through WeatherDynamics infrastructure. Temporary outages can affect these products even when other forecasts continue working.
Please email support with the affected location or radar station, approximate time, and a screenshot.
Location and Saved Places
Why does WeatherDynamics request location access?
Location permission allows WeatherDynamics to display weather information for your current position.
Location permission is optional. You can search for another place instead.
To change permission settings, open:
iPhone Settings → Privacy & Security → Location Services → WeatherDynamics
Does WeatherDynamics track where I travel?
WeatherDynamics is not designed to maintain a history of your movements.
It uses selected locations to request relevant weather information. Those requests may be processed by third-party weather services or WeatherDynamics infrastructure as described in our Privacy Policy.
Can I use WeatherDynamics without enabling location?
Yes. Search for a place and select it manually.
Offline Use and Data Availability
Does WeatherDynamics work without an internet connection?
Some previously downloaded weather information and saved settings may remain available on your device.
However, live radar, current observations, updated warnings, and new forecasts require working data connections.
Always check timestamps when viewing previously saved information.
Can I use WeatherDynamics as my only emergency-warning source?
No. WeatherDynamics is intended to supplement—not replace—official alerts and established emergency communications.
App notifications, data connections, and background updates cannot be guaranteed.
