DISCUSSION
Key Points:

* Breezy northwest afternoon and evening winds will remain a little stronger than normal during the next week. This includes the strongest winds at the coast south of Cape Blanco, and winds generally a little stronger in south central Oregon and northern California than in southwest Oregon.

* Light showers will be mainly near the higher terrain through this evening, except into Sunday for Coos and Douglas counties.
Amounts of 0.10 to 0.50 inches were common yesterday. Additional showers should mostly amount to up to 0.10 inches, perhaps up to 0.25 inches in eastern Douglas County. A few flakes of snow are still possible for the Cascades above 6000 feet today into early Sunday.

* Instability will be weak, but there is also a slight chance of afternoon and evening thunderstorms for Douglas County into northwest Klamath County (near Crater Lake)and from southeast Siskiyou County eastward,with the highest probability for southern portions of Modoc County... south of Alturas.

* This afternoon will likely be the coolest for quite some time, perhaps of the remainder of the summer, with highs around 20 degrees below normal. A gradual warming and drying trend under a stable air mass is then expected Sunday through at least into Wednesday, but with temperatures remaining below normal.

* Part of this cool to cold episode is east side lows on Sunday and Monday mornings at around 10 degrees below normal, in the 30s. The forecast Sunday morning lows are expected to remain above freezing, and reflect a blend of the NBM and an analog of recent readings to nudge values higher in consideration of expected cloud cover and MOS guidance. Values should be very similar on Monday morning with a slight warming of the overall air mass counteracted by lesser cloud cover.

* Low clouds are expected at the coast through Friday morning, with some lifting of cloud ceilings and afternoon breaks in the clouds, particularly from Wednesday onward. Otherwise, low clouds will return to west side valleys tonight into Sunday morning and each night at least into Wednesday morning, with the thickest clouds and longest duration of night and morning coverage for the Umpqua Valley.

* The upper level pattern during next week will generally remain trough-dominated. This weekend's cold system will be followed by a couple of weak shortwaves in the northerly flow on Monday, then a persistent, broad, but relatively weak trough Tuesday through Thursday or Friday. The details are too early to discern with confidence. It will mainly be dry, but weak instability and some shower chances cannot be ruled out...particularly for Thursday and/or Friday. Inland high temperatures in the 70s are expected to be common across our area.

* Weak ridging is likely at least for Saturday, perhaps for all of the holiday weekend with inland high temperatures returning to near or slightly above normal, in the 80s. This should also bring sunshine to the coast.
