.DISCUSSION...Satellite image shows clear skies over most of the
forecast area. The only exception is for a small area of marine
stratus in northern Curry and southern Coos County. Dry and mild
weather will continue through this evening.

An upper trough will approach the area later this evening with the
trough axis moving overhead tonight. Instability will be marginal at
best. Convective showers are possible in southeast Siskiyou, Modoc
and southeast Lake and Klamath County.

Isolated showers Wednesday should be confined to the same areas,
although they will trend farther southeast as the trough axis moves
southeast.

Weak upper ridging builds in Wednesday evening into Thursday
morning, then an upper trough will approach from the west resulting
in a chance for showers and isolated storms along the Cascades and a
slight chance of showers in western Siskiyou County and south
coastal mountains.

Friday and Saturday are shaping up to be cool and unsettled with
isolated to scattered showers, with showers most frequent in the
afternoon and early evening hours due to daytime heating.

The upper trough will begin to shift east Sunday with showers
diminishing and becoming more isolated.

Evidence is pointing towards dry and mild weather for the start of
next week. -Petrucelli

.AVIATION...22/06Z TAFs...Breezier conditions at the coast are
starting to weaken this evening. Flight levels look to remain at VFR
for most areas of northern California and southern Oregon. MVFR
ceilings could return to the Umpqua Valley early in the morning but
do not look as likely for coastal areas. Another push of stronger
northerly winds will return Tuesday afternoon. -TAD/Hermansen

.MARINE...Updated 300 AM Tuesday, April 22nd...Moderate to strong
winds, strongest south of Gold Beach will continue through this
evening. North winds will gradually diminish tonight, but seas will
still remain elevated enough for Small craft conditions to continue
with Hazardous Seas Warning conditions south of Port Orford into
Wednesday evening.

Calmer conditions are likely Thursday and Friday. Weak low pressure
will move into the waters Friday bringing scattered showers. Seas
are expected to remain on the low side with no marine hazards on
Friday. -Petrucelli
