The upper air flow has  switched more from the northwest cutting off the heavy moisture flow. One last disturbance moved southward away from us and taking the remaining moisture with it and you can see a surface high pressure area moving toward the West Coast. An upper level high pressure ridge (“Arch”shape in the jet stream) will build in over us and that means it will dry out for a while. Remember that, particularly this time of the year, when it’s not raining it is usually fogging.
