   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Severe thunderstorms are not forecast across the contiguous United
   States through tonight.

   ...Synopsis...
   An upper trough currently exists along the coastal Pacific Northwest
   this evening, and height rises will occur tonight as the wave moves
   northeastward across OR and WA. In the near term, a few
   thunderstorms will remain possible over coastal northern CA, and
   farther north across western WA beneath the cooler air aloft. Most
   of the instability is elevated over southern areas, but weak SBCAPE
   may exist near coastal WA. Here, low-level flow will veer to
   westerly coincident with the stronger midlevel cooling, supporting
   non-severe, low-topped convection.
