Today's Global Overview

The globe above shows today's 24-hour average temperature forecast. This forecast comes from the NCEP Global Forecast System (GFS), a state-of-the-art dynamical model initialized by satellite measurements and global meteorological station data every six hours. GFS is the core operational model used by the U.S. National Weather Service (NWS). Temperature values shown here are for 2 meters above the ground surface.

The globe above shows the difference, or anomaly, between today's forecasted average temperature, and the temperature climatology for this date averaged over the period 1979-2000. The anomaly field is calculated using output from the the NCEP Global Forecast System (GFS) and the NCEP Climate Forecast System Reanalysis (CFSR) models. Temperature anomaly values shown here are for 2 meters above the ground surface. Regional summaries are displayed below the globe. Click the image to see different viewpoints.

The globe above shows today's 24-hour average precipitation rate forecast (plus current snow, sea ice, and sea level pressure). This forecast comes from the NCEP Global Forecast System (GFS), a state-of-the-art dynamical model initialized by satellite measurements and global meteorological station data every six hours. GFS is the core operational model used by the U.S. National Weather Service (NWS). Click the image to see different viewpoints.

The globe above shows today's 24-hour average precipitable water forecast. Precipitable water, a proxy for humidity, is a measure of the total amount of water in a column of air that could be precipitated to the earth surface as rain or snow. This forecast comes from the NCEP Global Forecast System (GFS), a state-of-the-art dynamical model initialized by satellite measurements and global meteorological station data every six hours. GFS is the core operational model used by the U.S. National Weather Service (NWS). Click the image to see different viewpoints.

The globe above shows today's 24-hour average near-surface wind speed forecast. This forecast comes from the NCEP Global Forecast System (GFS), a state-of-the-art dynamical model initialized by satellite measurements and global meteorological station data every six hours. GFS is the core operational model used by the U.S. National Weather Service (NWS). Click the image to see different viewpoints.

The globe above shows today's 24-hour average cloud cover forecast (plus current snow and sea ice). This forecast comes from the NCEP Global Forecast System (GFS), a state-of-the-art dynamical model initialized by satellite measurements and global meteorological station data every six hours. GFS is the core operational model used by the U.S. National Weather Service (NWS). Click the image to see different viewpoints.

The globe above shows today's sea ice and snow conditions as reported by the NCEP Global Forecast System (GFS). Climatological (1979-2000) sea-ice extent for this day of the year is delineated in light blue. GFS is the core operational forecasting model used by the U.S. National Weather Service (NWS). Satellite-measured sea ice and snow are input to GFS daily to provide boundary conditions for the dynamical atmosphere 7-day forecast. Reliable daily satellite measurements of sea ice are available onward from November, 1978. Sea ice climatology derived from the NCEP Climate Forecast System Reanalysis (CFSR) model.
