Updated AVIATION discussion for 18Z TAFs
DISCUSSION
Satellite shows the Illinois Valley and Umpqua Basin have low clouds/fog as of 3 AM. The Rogue Valley warmed up more today, but RH's are nearing 100% now, so looking for fog development early this morning. A Freezing Fog Advisory is in effect through the morning for the Illinois Valley. Please remember that anywhere that has freezing fog could have icy surfaces. Skies are clear otherwise.
Once again, the ridge of high pressure will hold the weather pattern of strong inversions and stagnant air that leads to evening/overnight fog for west side valleys for the next several days. Warmer temperatures at the coast in the upper 50s to low 60s will be found this weekend. Upper 40s/ low 50s will be found east of the Cascades.
Even if there is clearing this afternoon, fog will quickly return to the same spots this evening. High pressure is forecast to remain in control for the next several days, although there could be a disturbance that finally reaches the western US next weekend. Other than that, there will be dry conditions everywhere and fog in west side valleys. -Hermansen
AVIATION
17/18Z TAFs...Fog remains in the Umpqua and Illinois Valleys as well as parts of the Rogue Valley. Fog is expected to decrease through the morning, with VFR levels across the area possible later in the afternoon.

MARINE
