A weak front moving into the Pacific Northwest will push south and east this afternoon & evening. This will bring increasing cloud cover to all of Southern Oregon, but the system will weaken as it moves south, allowing for showers to dissipate and become less widespread as it moves into our forecast area.
Even so, isolated rain showers cannot be ruled out in all locations. Snow levels will stay fairly high today (around 7,000’) so only rain is anticipated. Another day of above normal temperatures is anticipated today, however the clouds in place today will keep afternoon highs slightly cooler than Sunday.
By tomorrow, a large ridge of high pressure sitting over the West will bring a prolonged period of dry weather to the region. This will allow for fog to build in West Side Valleys through the course of the week, bringing more dense conditions as well as less sun into the week’s end. Christmas may be our first day of dense fog in the Valley, unfortunately ..keeping temperatures in the 30’s.
Over Siskiyou County & the Klamath Basin, fog will burn off eventually through the course of each day, unlike the valleys. Temperatures will likely stay cool in the lower elevations, due to strong inversions building in the overnight hours all week long.
Above the fog, sunny skies and mild temperatures are expected through the end of the 7 day forecast. This means Medford, Mt. Shasta & Klamath Falls will all end the calendar year on the driest note ever in history for their city.
