   On Sunday, an upper trough is expected to move eastward across
   portions of British Columbia and Alberta, while a slow-moving upper
   trough further to the south will approach the northern California
   coast. Some slight weakening of the upper ridge over the Great Basin
   and central/northern Rockies is possible in response to these
   features. At the surface, a low pressure area is expected to
   strengthen late in the period across the southern Canadian Prairie
   provinces, as a trailing cold front approaches portions of the
   northern High Plains by Monday morning. 

   ...Southern OR/Northern CA into the Great Basin...
   Limited but sufficient monsoon moisture will support isolated to
   widely scattered thunderstorms on Sunday afternoon/evening from
   portions of northern CA/OR into the Great Basin. Relatively slow
   storm motions may allow for localized wetting rainfall, but
   thermodynamic profiles will support some dry thunderstorm activity,
   so an isolated dry-thunderstorm area has been included to cover this
   threat. The upper trough approaching northern CA has some potential
   to increase thunderstorm coverage across portions of this area,
   though this remains uncertain given some guidance indicating this
   system will stall off the coast.
