Thursday’s storm system did not turn out to dump as much rain as the computer models were suggesting. These weak disturbances that have moved in all week have been rather difficult to forecast for. The showers that do exist over the viewing area will begin to taper off this evening from West to East. Activity will be very isolated along the Coast and in Siskiyou County and more scattered in the Basin.
By Friday, high pressure will begin building back into the NW but the lingering moisture will still allow for very isolated showers to develop. Cloud cover should decrease throughout the day and although a passing sprinkle may fall, skies should clear to partly sunny.
Again Saturday, another disturbance is going to move through Oregon. The question is where will it track. All of the model runs are showing different scenarios. It’s possible the shortwave passes to our North, and nobody sees a drop, however I am keeping the chance for a sprinkle in the forecast for the afternoon. Aside from this slight chance for an extremely light shower, it seems like most of the viewing area will be under partly cloudy conditions. Temperatures have been below seasonal values this afternoon and will remain fairly average into the weekend.
