DISCUSSION
Satellite imagery shows marine stratus along the coast north of Cape Blanco, Coquille Basin and now filling into most of the Umpqua Basin and along the Cascades. The marine stratus could also get banked up along the north Facing slopes of the Siskiyous and possibly the south end of the Rogue Valley, just south of Ashland towards daybreak.

Dry weather will continue today with the aforementioned cloud cover dissipating during the morning hours with mostly clear skies by the afternoon. Onshore flow will result in cooler afternoon temperatures for interior locations this afternoon. Along the coast, the marine stratus could linger north of Cape Blanco for most of the day, although it could peel back just off the coast for a few hours late this afternoon and early evening, before returning.

This weekend we'll be under the influence of weak upper troughing, with the upper trough north of our area Saturday, then dropping south Sunday. However the track of the upper trough does not favor precipitation. So while it will remain dry, afternoon temperatures will be in line with seasonal norms. We'll still experience the typical late afternoon and early evening gusty breezes for the interior westside valleys and east of the Cascades this weekend.

The majority of next week will be dry. The one exception could be Tuesday afternoon and Tuesday night as a weak upper trough drops in from the northwest. Odds are it will remain dry, but a few showers cannot be ruled out along the north coast, Umpqua Basin and northern Cascades.

Wednesday and Thursday are likely to be dry, then as we get towards the end of next week, the operational ECMWF shows a stronger upper low moving into our area bringing a higher chance of precipitation.
In contrast the operational GFS is dry with the upper trough sliding over the interior which typically results in dry weather. Looking further, some members the GFS ensembles show precipitation in our area and the majority of the individual ECMWF members show precipitation, therefore we'll keep at least a slight chance of precip in the forecast for portions of the forecast area.

AVIATION
17/06Z TAFs...Along the coast and just offshore, MVFR and IFR ceilings will persist north of Cape Blanco and beyond 5 nm from shore this morning, then skies will clear with VFR ceilings the rest of the TAF period with weak offshore flow. Gusty north winds are likely late this morning into this evening, with breezy north winds lasting into tonight.

Inland, the marine stratus has filled into the Coquille Basin and most of the Umpqua Basin and is banked up along the Umpqua Divide and Cascades, with MVFR ceilings. It's possible the marine stratus could slip just over the Umpqua Divide towards daybreak, but the Medford terminal will remain VFR. The marine stratus will burn off late this morning with VFR ceilings returning, then low clouds will develop again late this evening in the Umpqua Basin resulting in MVFR ceilings for Roseburg. Elsewhere, VFR conditions will continue with breezy winds in the afternoon and early evening hours.
