A potent shortwave currently nearing the north Oregon Coast will
lift toward the South Central Cascades early Saturday
morning...drifting into portions of the Western Basin. The feature
will likely result in isolated lightning strikes but still has
the potential to produce scattered thunderstorms and abundant
lightning. The cluster of storms is expected to drift over Yakima
County then spreading north and northeast through early Saturday
morning. This activity is expected to weaken and drift to the
northeast through the day. Although it still may produce isolated
lightning strikes...the threat for abundant lightning to the north
