Then on the right hand side of the page under "Select a Forecast Hour," click on "072." That will show the forecast snowfall amounts that should exist by 12z (7:00 a.m. EST) on Monday.

On the right side of the page, the select-dropdown currently reads "12z Friday, Jan 23." That's when the current model was last run. You can select previous model runs to see how the snowfall predictions have varied.

The next run will occur at 1:00 p.m., but the updated data does not appear on the website until three to four hours later. So check back after 5:00 p.m.

When the select-dropdown reads "18z Friday, Jan 23" then click the 66-hour forecast button. You want the forecast map to say "valid at 12z Mon, Jan 26, 2015."
