This will induce a ridge over the Pacific Northwest. The atmosphere will again be very stable. Expect poor ventilation conditions. On Friday the upper low moves to about 600 miles west of San Francisco, California. The ridge axis shifts east and this will allow the low to spread some moisture northward from California and Nevada. Precipitation amounts should be very light, but the atmosphere will remain stable and ventilation conditions remain poor. The remains of the upper low move closer to the California coast on Saturday. Upper flow over the Pacific Northwest goes to nearly due southerly. With warm air aloft and plenty of cloud cover and low sun angle for minimal surface heating, maximum mixing heights remain low and most of the region will experience poor ventilation conditions. </span><o:p></o:p></p><p class=MsoPlainText><span style='font-family:"Courier New"'> </span><o:p></o:p></p><p class=MsoPlainText><span style='font-family:"Courier New"'>2.
