Rain and wind are in the forecast tonight as a warm front approaches the area. Tropical moisture will be ushered in with these next few systems bringing with it plenty of heavy rain. After the warm front passes tonight, a weak cold front will move in right behind it on Friday morning, this will bring snow levels down to 5,000′ around the Crater Lake and Diamond Lake area but expect minimal travel impacts. This will bring lighter rain and an ease of the winds Friday afternoon.
The next round of storms arrives right on the heels of the last one with another warm front Friday evening into Saturday. This system will bring the strongest winds and the heaviest amounts of rain Friday night into Saturday afternoon. A FLOOD WATCH is in effect until Sunday evening as we will get persistent rain throughout the next few days. Urban street flooding (especially near intersections) and small stream flooding is possible also areas with previous fire burn scars and loose soil could experience rock slides or debris flows. High winds throughout the next few days will warrant a HIGH WIND WARNING for the east side tonight until Friday at 4:00 pm then a HIGH WIND WATCH has will go into effect Friday evening and lasting until Saturday evening, though this will get updated to a warning once we get closer to the threat. Sustained winds on Saturday for the coast and upper elevations will be in the 40-55 mph range with gusts up to 80 mph and even up to 90 mph in the coast headlines, that’s hurricane force! Small trees and power lines could be blown over during these high wind events and precautions should be taken.
Rainfall totals through Saturday at the coast are forecasted to be anywhere from 5″ to 13.” The valleys should see anywhere from 2″ to 4″ and the east side will get anywhere from a quarter of an inch to 2.”
After the passage of the cold front Saturday, rain and winds will calm for a short period of time but snow levels will drop to 3,000′ so any showers early Sunday above that will be in the form of snow but impacts will be minimal. Sunday into early Monday will be our next break from the rain. A colder air mass will move in behind the front will drop snow levels to around 3000′ Sunday and even lower by Thursday potentially as low as 2,000′. Next week there is a good chance we will see substantial snow for the Cascades and Siskiyous! Everywhere else will see mainly rain as the active weather pattern continues.
