This is the second time we have come upon the predictive satellite and radar product, but it's worth a revisit. Predictive Satellite and Radar is a product offered by weatherTAP that lets you see the precipitation and cloud cover that the North American Model (NAM). The forecast extends out to 36 hours from the time of the model run. The model run images are in 3-hour time steps.

You can always tell what time the model data was constructed by looking in the lower left corner of the image. The run time and the period of time the model is valid are both shown here. Here is an example:

The NAM model is a major weather model used for short-term weather forecasting.

With this weatherTAP product you can always choose to turn off the satellite or the radar by unchecking those options on the left hand side of your screen.

Revisiting predictive satellite and radar is a good stepping stone into what we'll be discussion next week, the model data page offered by weatherTAP. Don't worry, we'll take things in baby steps. Model can be difficult to explain and interpret but I think you'll understand it a lot better after our model lessons! As always, if you have any questions at all just let me know!
