**UPDATED TO ACCOUNT FOR WINTER STORM WATCH**
The arctic air mass that has been mentioned for days now is bringing temperatures well below normal. The Klamath Basin is starting the day off in the single digits this morning. Highs today will be in the 20’s & 30’s across inland locations.
A freeze warning is in place for the coastlines of Curry, Coos and Douglas Counties through 10am Wednesday. A freeze watch is also in place for these locations for Thursday morning, which will likely become a freeze warning by this afternoon.
Quiet and dry weather will stay in place for both Wednesday and Thursday. The coldest morning we have seen so far this season, will likely unfold this evening. Morning lows will be in the mid to upper teens across west side valleys and subzero morning temperatures are expected in the Klamath Basin.
A quick moving but fairly moist weather disturbance is expected to move into the region late Thursday night into Friday. The National Weather Service has placed all areas west of the Cascades under a winter storm watch. This includes Curry, Douglas, Jackson, Josephine and Sikiyou Counties. With the very cold air in place, any moisture that moves into the forecast area would be in the form of snow.
This storm system has the potential to bring snow to valley floors Friday. The exact timing of it’s arrival will determine whether or not the snow will stick to valley floors. If winds shift southeasterly, we’ll likely see a rain/snow mix or snow melting on contact.
However, right now the ingredients coming together would support snow sticking over west side valleys, a couple inches in the foothills and at least 3″-6″ in the higher elevations. Because this is such a rare occurrence in the Valley, it will be watched with a close eye through the next 24 hours.
Regardless, it’s very likely snow showers will fall across the Valley through Friday morning. An even colder air mass will follow this front and this weekend will only bring highs into the 20’s across the Valley. Dry weather though, is expected both Saturday and Sunday at this time.
