....DISCUSSION...
Upper troughing is expected to deepen across the central and eastern
CONUS from D4/Sunday through at least D6/Tuesday. At the same time,
ridging will build across the western CONUS. This overall pattern
will likely shift eastward by D7/Wednesday as another upper trough
approaches the West Coast. As a result, an amplified
trough/ridge/trough pattern will likely extend across the CONUS by
early D7/Wednesday.

Stable conditions are expected to prevail across the majority of the
CONUS from D5/Monday through D8/Thursday. A few thunderstorms do
appear possible from the middle to upper OH Valley into Upstate NY
and central PA on D4/Sunday as a shortwave trough and associated
surface low/cold front move through the region. Strong large-scale
ascent is anticipated ahead of the shortwave, with robust mid-level
flow moving across the region as well. However, the better low-level
moisture and associated buoyancy will be displaced south, likely
keeping the overall severe threat low.
