A warm front is bringing increasing rain and wind to the region this evening with the heaviest rain falling overnight into tomorrow morning ahead of a cold front. While in the warm sector tonight and Thursday morning snow levels will climb to 6,000 to 7,000 feet, so this will mainly be a rain event for most areas with snow at Crater Lake and Diamond Lake. After the cold front passes Thursday snow levels will drop to 5,000 feet Thursday afternoon and down to 4,000′ overnight Thursday. The heaviest precipitation will be over when snow levels drop but those heading of the Cascade passes should be prepare for winter travel into Friday morning.
An upper-level trough will sit over the Pacific Northwest Friday bringing continued showers though showers will be lighter compared to tonight. There will be a break in the rain late Friday into Saturday with rain returning to the coast Saturday afternoon and spreading inland late Saturday. Spotty showers will continue Sunday then drier and warmer weather returns next week.
