Fog Inversions to set up for the week!

As the ridge sets up as we speak, we will see a foggy week ahead of us. Why? Well when its clear and the ground is moist, we see fog develop. But as the fog develops, warm air above traps the fog and cold down below causing the mountains and the coast to be way warmer than the valleys. Also know as Inversions. So expect a foggy week and cool temperatures as highs and maybe start to see the sunshine more earlier by the end of the week. If you remember, this happened a lot last year here in McMinnville. Ok I have a question to answer by a Blog Viewer (haha that's what you are right now) and its by "Chinookwind" and he states: "ok, i'll bite....so many times we have seen this pattern set up here in the PNW over the past few years...coolish, wet fall then, boom, the ridge sets in and we are basically high and dry for most of the rest of the winter. i am just new to weather and dont understand enough about the models and their secrets, however...this ridge out there seems enormous and very strong...can you post links to other years where a ridge of this type was short lived, with similar indices and we ended up with a good year? by good year i mean a normal year with good mountain snows for the next seasons water supplies.we barely skated thru this last summer. " First of all, its not uncommon to see these types of ridges form. It happens most of the time in November actually. This is not the end of the winter, because winter hasn't even started so whats all the fret about? Sure i'd love to see snow in November but that is not the likely case this year. Second of all, I see this ridge breaking down by the 25th up to the end of the month as of current models. It also looks like a miny retrogression at the end of the ridge that could possibly bring cold air into the region but again, that's just too far off. I tried to find records that you have asked for but I haven't had too much free time to do so, so im gonna ask Jim Hinkle to chip in with that section and will get back to you. Any other questions? Take Care!
