...WA/OR/ID...
Full sunshine and dewpoints in the 50s to lower 60s are present
today over much of the Pacific Northwest region, where afternoon
MLCAPE values will range from 500-1500 J/kg. The persistent upper
low off the coast will continue to track northward today, with
moderately strong southerly deep-layer flow across the region. This
will lead to a conditionally favorable environment for
severe/supercell thunderstorms. Most CAM solutions suggest at least
isolated cells forming this afternoon and early evening over eastern
WA/OR and western ID. Any persistent storm in this area will pose a
risk of damaging wind gusts and hail. The threat should begin to
diminish after 03z.
