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. Click the image to see different viewpoints.
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

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 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 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.
