....NO THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Thunderstorm activity is forecast to be minimal at best across the
U.S. on Sunday.

....Discussion...
The large-scale pattern will remain largely unchanged on Sunday,
with zonal flow aloft to remain in place.  Disturbances in the flow
field -- largely across the northern U.S. and southern Canada --
will continue advancing eastward through the period.

A weak surface low is progged to lie near the Manitoba/North Dakota
border early Sunday, associated with the aforementioned short-wave
energy embedded in the fast westerlies aloft.  This low is expected
to deepen with time, as it shifts across Ontario, allowing continued
southward advance of a cold front across the Intermountain West, and
the Plains.  With a reinforcing advance of Arctic air spreading
southward behind the front, and high pressure prevailing south of
the boundary, little risk for thunderstorms is evident through the
period.
