TONIGHT: We will see mostly cloudy skies as the marine layer pushes deep into the valleys again with overnight lows in the upper 40s to low 50s with light winds out of the North at 5 to 10 mph and gusts up to 15 mph. Some patchy fog will form by morning but burn off around 10 AM.
TOMORROW: We will start off with mostly cloudy skies and temperatures in the upper 40s to low 50s and light winds and light fog. As we move into the afternoon the clouds will burn away and lead to sunny skies in the afternoon with highs in the mid-70s to low 80s with light winds out of the North at 5 to 10 mph.
MID WEEK: An upper ridge near 135W keeps northwest flow over the region through Wednesday. A weak but dry shortwave in the northwest flow moves over the area early tomorrow, so expecting another robust marine layer in the morning. The upper ridge will move closer to shore later Wednesday and Thursday, and traverse western OR/WA Friday morning. While offshore flow never develops, the marine layer should be considerably more shallow both Thursday and Friday, for mostly sunny skies and seasonably warm temperatures. Saturday sees the ridge flatten and move eastward, bringing a benign westerly flow and thickening marine layer, for morning clouds followed by afternoon sun.
