.SYNOPSIS...
Cooler temperatures and the occasional threat of showers and
thunderstorms will linger the rest of the week and into the
weekend. Thunderstorms will be slow moving with the cores of these
storms containing very heavy rainfall. This may lead to some rapid
runoff in steep terrain and possibly flash flooding or debris
flows, especially on burn scars along the east slopes of the
Cascades with Friday having the best potential. Warmer and drier
weather is expected toward the middle portion of next week.
