SREFs: Day 1

Finally, graphics from 09 UTC SREF runs for day 1 can be seen by clicking on the various cells in the table below (cells with "x" do not have graphics). These SREF runs would be used by the day shift as input into the forecast process.

In the table below, each link "pops up" a new window with a different SREF product found on the web. The animations show each ensemble product from zero to 63 hours. All fields are shown for the CONUS and adjacent areas. When you are done with each animation, click the upper right hand "X" in the window to close it. Multiple animations may be open at the same time.

Close-ups of selected graphics from SREF model data can be seen here. The sections of the CWA asked about in the question are defined on the map.
