WEATHER DISCUSSION

Short Term:

This week will start off with another pesky storm system that will move through and bring rain, wind, and snow to our forecast area. The good news is that this active weather pattern is bringing much needed rain and snow to the dry areas; but with this change in weather conditions comes potential for mud and landslides. After the devastating slide in Washington state, officials believe that the heavy rain falling near Portland could bring possible slides.

This storm will deliver help to our drought-stricken area. The system will bring a strong cold front and ahead of it will come the heavy rain and wind. The Coast will see these conditions first on Monday afternoon. A WIND ADVISORY will go into effect Monday for the Shasta and Rogue valleys starting at 10 a.m. Sustained winds in this area will be in the 20-35 mph range. Gusts could get as high as 50 mph. High profile vehicles traveling in these areas could be impacted. Rain will move in ahead of the front and get heavy at times Monday evening. The heaviest amounts of rain will fall below 3,500′ in Siskiyou and Del Norte Counties. The system is taking on a SE flow and will actually skirt our area to the South. The reason Southern Oregon will see rain is because of the winds out of the South pushing up the rain from Middle California. This system will not last long. In fact, rain will subside Tuesday morning and only post frontal scattered showers will remain into the afternoon.

Snow levels are already low starting out because of the cold front that passed last Friday. They will drop even further with the passage of the front on Monday. Snow is expected above 4,000′ in the Basin, and above 3,500′ in the Cascades and Siskiyous. The southern track of this storm will cause the heaviest snow to fall in Northern California. Snow levels will drop to around 2,500′ Monday. The best accumulations however will be above 3,500′. A WINTER STORM WARNING will go into affect at 2 p.m. Monday and continue until 5 a.m. Tuesday. This WARNING is for Eastern Del Norte and Western and Eastern Siskiyou Counties.   Snow accumulations of 4″-8″ are expected. This snow will have a high water content and will be wet and heavy. Largest snowfall totals will happen late Monday night after the front passes.  Any roadways above 3,500′ will be susceptible to snow and slush. This will be especially true for Hwy. 3 through the Scott Mountains. If driving in these areas overnight Monday or early Tuesday morning, use chains or traction tires. Allow for extra time and drive slowly. This heavy snow can also bring down tree branches and power lines.

Long Term:

Starting Wednesday, a small area of high pressure will build into the area and it looks like we will stay relatively dry with a few clouds. This will be short-lived as another upper level disturbance will bring another round of precipitation on Thursday. Friday will see light shower activity and then rain will pick up into next weekend. Late Sunday, we should see a stronger ridge of high pressure and as of now the models are trending towards drier and warmer next week.

Thanks for logging on and be safe out there!
