Well round 1 has come to an end, leaving quite an imprint over the area. Over 4″ of rain has fallen at the Coast near Brookings and over 1″ in Medford. Much of the Basin saw measurable rain as well, with Klamath Falls picking up more than a half of an inch. If you’re sick of the rain, treasure today. If you aren’t, hold on a few more hours. Much of Thursday will act as a break between storms, with plenty of clouds, fog & very spotty showers.
Snow levels are around 5,000′ and some of the showers developing overnight were in the form of snow at Crater Lake. Later today, round 2 will arrive increasing our winds and bringing another long period of widespread and moderate to heavy rainfall. This warm front will push into Southern Oregon/Northern California around 4 & 5 o’clock tonight. Rain will be ongoing through the overnight hours with snow levels staying high.
The front will then stall over the Northwest on Friday — so the rain continues. It will then slowly travel down the I-5 corridor and snow levels will gradually drop as the cooler air settles in behind the frontal passage. This will change the rain over to snow for the higher elevations.
Friday night rinse & repeat — this same warm front/cold front process will happen all over again through Saturday. Strong winds are expected with not only tonight’s storm, but most certainly Saturday’s storm. High wind watches are already in place for parts of the Basin & for the immediate Coastline Friday night into Saturday to account for this potential.
At this time, a flood watch remains in place through 4pm Saturday. With another 1″-3″ of rainfall expected across the West Side & 5″-10″ at the Coast, signficant rises in creeks & streams is very likely. Even in the rivers, despite the low water levels, heavy & fast rainfall rates may lead to flooding. This is especially true at the Coast. This flood watch includes all of the Coast (Curry & Coos Counties), Josephine Counties, much of Douglas Counties & also Western Siskiyou County. Grants Pass & Cave Junction are included in this watch.
