...UNSTABLE CONDITIONS CONTINUE, WITH THUNDERSTORMS DEVELOPING
ONCE AGAIN TONIGHT AND SUNDAY...
.Unstable conditions will persist once again today, before an
oncoming weather system shifts the threat from instability to that
of thunderstorms. Clearing has been observed across central
Oregon, and with that, scattered thunderstorms are expected to
develop this evening. Storms are expected to develop over the
eastern mountains tomorrow afternoon as well, however forecast
confidence remains on the lower end, so will hold off on upgrading
the watch there for now.
