.Updated Aviation Discussion.
DISCUSSION
Satellite image shows marine stratus along the coast and has made it's way inland over the coastal counties and gradually filling into portions of the Umpqua Basin. So far, surface observations have not reported rain or drizzle, just a low cloud deck with reduced visibility. Models do show light QPF in the above mentioned areas. However, this is more likely a result of the stronger marine push, deepening marine layer as opposed to actual precipitation. Even so, could not rule out patchy areas of drizzle this morning along the coast and over the marine waters.
Marine stratus will continue to fill into the Umpqua Basin between now and mid morning and get banked up along the Umpqua Divide, with some slipping just over the Divide, but the Rogue and Illinois Valley should remain clear with clear skies expected over the rest ofthe forecast area.
It will remain dry through Thursday. An upper trough will be moving towards the area from the northwest Thursday afternoon. The net result will be slightly cooler afternoon temperatures for the interior and gusty afternoon and early evening breezes east of the Cascades and interior westside valleys.
The upper trough will settle over the area Friday and Saturday.
The upper trough is pretty strong for this time of the year and is likely to result in much cooler temperatures (15-20 degrees below normal) for the interior with showers likely west of the Cascades Friday afternoon, then over most locations Friday night through Saturday. Instability parameters suggest instability is marginal at best and there was not enough evidence to support a mention of thunder Friday and Saturday, but this will need to be looked at again.
The cool and unsettled weather will be short lived with dry and much warmer weather returning by the start of next weeek, but there is some evidence suggesting another upper trough could settle back into the Pac NW late next week. -Petrucelli
AVIATION
18/12Z TAFs...Satellite image shows marine stratus along the coast, and over the coastal counties. The increased onshore flow has allowed the marine stratus to move farther inland and it's filling into portions of the Umpqua Basin. It will be a close call for the marine stratus to impact Roseburg, and it's possible it could remain west of Rosburg this morning. However confidence is not high enough NOT to include MVFR ceilings there for a few hours this morning. The marine stratus will burn off with clear skies and VFR ceilings late this morning and afternoon with gusty afternoon and early evening breezes at Roseburg.
Meanwhile along the coast and just offshore, IFR with local LIFR ceilings with reduced visibility will be the predominate condition for the morning hours. Ceilings will lift in the afternoon, but it may not lift high enough for VFR conditions. Low ceilings are expected again this evening and tonight with IFR and local LIFR.
Elsewhere, VFR levels will continue through the TAF period with gusty afternoon and early evening breezes.
MARINE
Updated 230 PM Tuesday, June 17, 2025...A weak disturbance will result in areas of stratus and possibly even some light rain showers or drizzle into Tuesday morning with light to moderate winds. A brief thermal trough will produce gusty north winds and steep seas Wednesday afternoon through Thursday evening south of Cape Blanco. Another system could bring showers Friday into the weekend.
