How much snow will fall in each 6 hours, in inches on the ground: where a storm turns to snow, and how heavy. How to read it.
What the snow, 6 hours map shows
How much snow will fall in each 6 hours, in inches of snow on the ground. Played, it shows where a storm turns to snow and how the snow moves through the mountains and the plains.
How to read it
- Under 1 in
- A coating; roads can still turn slick.
- 1 to 3 in
- Snow to clear.
- 3 to 6 in
- Heavy snow; travel slows.
- Over 6 in
- Very heavy snow, 1 in an hour or more; travel stops.
What it is for
- Time the heaviest snow of a storm.
- See where rain turns to snow along the storm’s track.
- Plan travel around the worst hours.
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=fsn, the times of its frames.
