The upper level airflow from over the Pacific Ocean is pumping more waves of moisture into the Pacific Northwest. A frontal system moved through Oregon into Montana decreasing the rain chance for a while. A second storm system (off to the west over the Pacific Ocean) will move in between late tonight and Friday, and if we are lucky, after its passage it should be drier over the weekend, with maybe a just a slight chance of sprinkles Saturday night and Sunday into early next week. With the record rainfalls we have seen recently it would be nice to get at least some sunshine and dry weather.

Advisories: A HIGH WIND WARNING IS IN EFFECT FROM 9 PM THIS EVENING THROUGH 4 AM FRIDAY FOR THE SOUTH CENTRAL AND SOUTH OREGON COAST. A WIND ADVISORY IS IN EFFECT FROM 4 AM UNTIL 2 PM FRIDAY FOR CENTRAL AND EASTERN LAKE COUNTY.
