Notes:

• Not all options apply to every level and/or model. Blank maps or missing data will result if the requested data are not available.
• If the "latest" model data option doesn't work, not all new model data may have been received. So, try the "previous" option.
• Model base times used here are only for 00Z and 12Z model runs.
• All of the new NCEP forecast front data arrive anywhere between 6-7 hours after model base time and won't be accessible here until they do arrive.
• NCEP frontal forecasts only cover the North America region.
• Forecast times are only available for 12, 24 36, and 48 hours.
• Only NAM (CONUS & AK) and GFS forecast model data are used in this application.
