...Pacific Northwest...
Isolated low-topped thunderstorms will remain a possibility today
along coastal portions of Washington and Oregon. This scenario is
supported by modest moisture and steep mid-level lapse rates
coincident with low-amplitude cyclonic upper flow. Buoyancy will be
quite limited overall, but somewhat more stout updrafts, including
the possibility of small hail, may occur through early/mid-afternoon
along the Washington coast. Thunderstorm potential is likely to
diminish into this evening/overnight as upper heights begin to build
and mid-level temperatures warm.
