How it is made
The forecast maps are drawn from the national blend of the forecast models: the models joined into one forecast and corrected against what each place has measured, on a grid 1.6 miles across, the forecast the country’s forecasters start from. Each of its main runs, four a day, is read whole, laid onto the same grid of latitude and longitude as the radar at 2.8 miles a cell, and played forward from now.
A frame every 6 hours for 7 days, played as a loop of 1 to 7 days. As data: /radar/now.json?show=fqpf, the times of its frames.
