A very different day today. The front is well past us now, rain has stopped, and most of the area is either clear or in fog--especially near water or in low areas (see pic near Lake WA). Dense fog is actually a sign of good weather ahead. Why? It generally forms on clear nights that allows the surface to cool effectively (the surface loses heat due to infrared radiation to space...if it is cloudy, that doesn't work well). Today should be sunny in most of the region, with temps reaching into the 50s. Tomorrow should be even better...as high pressure builds to the east of us, offshore flow will really dry and warm things up. So tomorrow should get into the upper 50's and lower 60s. Perfect fall day. A weak front should cross the region Thursday..but we will be lucky to get a light shower out of it.
