An upper level high pressure ridge (Shaded “Arch” shape) will keep the rain away for your Friday and allow the warm air being pushed in by the warm portion (red line with semicircles on it) of a frontal system that has moved through. March has come in like a lamb for sure. The cold front portion will slide in Saturday returning the cooler air and rain. An An upper level trough of low pressure (Shaded “U” shape) will bring us back to the rainy weather as it replaces the ridge. Another frontal system will approach the Pacific Northwest Monday continuing the chance of rain.
