Short-lived high pressure (shaded “Arch” shaped area offshore) brought out the sunshine Sunday warming us up more than I expected and should hold off more wet weather until midweek. A cold front moved into Oregon bringing the temperatures down, but they will still be a bit above normal. A trough of low pressure (Shaded “U” shaped area with blue arrows in the Gulf of Alaska) will move in behind the ridge sending waves of moisture at us. A frontal system will push into Oregon Wednesday with more behind it bringing increasing waves of rain.
