________________
Advisories: A HIGH WIND WATCH IS IN EFFECT FROM MONDAY EVENING THROUGH TUESDAY EVENING FOR THE SOUTH CENTRAL AND SOUTH OREGON COAST.
________________
Weak, short lived high pressure will dry us out a bit today. 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 will push southward into Washington and Oregon bringing colder air south producing falling temperatures and falling snow levels as the next frontal system moves in to California spinning some moisture our way. Thanksgiving will be wet and there may be some new snow in the mountains for the skiers.
