There's frequent questions about why MyRadar only shows radar for the recent past, but not the future. Truthfully, the answer is that we don't have the technology of larger weather services to render future radar. We get our radar data from land-based dopple radar systems, not computer- or satellite-generated images that render predictive radar. The computing power needed to do so is HUGE, and extremely expensive. 

In addition, predictive radar can be inaccurate, especially when trying to show radar several hours in advance.  However, like all tech, things get better and cheaper over time. Once the tech is more reliable and affordable, we will start looking into how to go about incorporate future radar to the app.

MyRadar processes weather data from over 150 ground radar stations centered around the United States. Every 5 or so minutes, the ground radar station pushes out the latest weather data its recently collected. That push gets sent out to our servers, which begin processing the data so it can show up in the app itself. This process takes around 5-10 minutes to complete, hence the radar loop in the app itself stopping 5-10 minutes short of the current time.

If MyRadar is taking longer than 10 minutes to load new radar data, you might need to check some of your device's settings and internet connection. Here are a couple articles that could help:
