.DISCUSSION...Radar image is showing isolated showers mainly
centered along and west of the Cascades. Showers should remain
isolated for most of the morning then will increase in the
afternoon with showers mostly concentrated north of the Umpqua
Divide and along the Cascades. Also looked at several instability
parameters and the data suggest it will not be unstable enough for
storms this afternoon and evening and they have been removed from
the forecast. The main resson for the lack of storms is ample
cloud cover which will keep temperatures from reaching convective
values due to limited daytime heating. Also, precipitation
amounts were adjusted lower for this morning due to the isolated
nature of the showers.

Showers will gradually diminish tonight, but cloud cover will
remain plentyful therefore temperatures will be slow to fall at
night. A few locations east of the Cascades could get close to
freezing towards daybreak Sunday if there`s enough clearing, but
clearing tonight may be brief and not lasting for a significant
amount of time. -Petrucelli
