________________
Weak, short lived high pressure dried us out a bit. A strong upper air trough of low pressure (“U” shape in the jet stream will be rolling through Oregon keeping the moisture level up. A frontal system moved southward on the California coast spinning some moisture northward, but not reaching us. Another frontal system will push southward into Oregon bringing colder air south producing falling temperatures and falling snow levels as the next cold front sweeps through just in time for Thanksgiving which will be wet and there may be some new snow in the mountains for the skiers.
