ECMWF Weekly Maps

May 16, 2013

Twice a week we receive the monthly run of the ECMWF model.  Here are the upper-level height forecasts broken down by week.  So each map is an average for the week of all the ensemble members.

Notice the cold upper low or at least an open trough is there through at least the next two weeks, pretty much what we see on the operational maps.
