There is high confidence of a quiescent period for severe
thunderstorms during the extended period.  A large-scale mid-level
trough will exit the East Coast on Monday (day 4) with ridging
occurring over the central U.S. on Tuesday (day 5).  Models are in
good agreement showing a quasi-zonal flow regime over the contiguous
United States on Wednesday (day 6) followed by increased model
spread.  The operational ECMWF has been consistent the last few
model runs in showing the development of a large-scale trough over
the West Coast on Friday (day 8).
