Rain showers have been developing this morning along the Coast and these showers are gradually making their way inland through Douglas County & Northern Jackson where they then run into the Cascades and turn to snow. Showers through much of today will mostly be at the Coast and along the Cascades, ahead of tonight’s storm system.
The cold front will arrive later today, around 5 & 6 o’clock at the Coast, and between 6 & 8 o’clock for West Side Valleys. Snow levels will stay around 4,000′-5,000′ throughout today before dropping to 2,500′ by tomorrow morning. A winter weather advisory is in place for 4pm this afternoon through 4am tomorrow for the Cascades & Siskiyous above 5,000.’ This advisory is for accumulating snow & also blowing/drifting snow overnight. 6″-12″ of snow is expected above 5,000′ with the higher accumulations near the Crater Lake & Diamond Lake Areas. Below 5,000′ a couple of inches will likely fall as well.
Mt. Ashland will likely see 2″-4″ of snow from tonight’s front & the Basin 1″-3.” North of Highway 140 in the Basin, 2″-3″ is likely & south of Highway 140 1″-2″ is likely. Siskiyou Summit will see snow showers early tomorrow morning, making the pass slick for the morning commute. A light dusting to 1″ of snow is likely over the summit by tomorrow.
Showers will gradually taper off throughout the day Wednesday, lasting the longest in the Cascades. Snow levels will stay around 2,500′ – 3,000′ through the afternoon, making it a cool day for much of the higher elevations. Another storm will push down the I-5 corridor Thursday afternoon but weakens as doing so. Only isolated showers are expected for West Side Valleys for this time period, snow showers for the Cascades & rain showers for the Coast. Elsewhere should remain dry.
High pressure builds into the area Friday and will help to make a return to the dry conditions we are ever so used to this winter. This dry weather will be ongoing through early next week.
