Snow Chances Looking Grim and a Weak Storm.

Yesterdays so called storm was not all that impressive as it was forecast. Rainfall total at PDX was only 0.49" at my house however it was 0.93". PDX also reported a gust of wind at 40 mph which is strongest since mid march.
Now on to the snow outlook
Here is the image of the 72 hour snowfall from the 12z rpm model.
   Notice how all the snow is only over around 1,000 ft
Temperatures are going to be just to warm for snow both Friday and Saturday however this does not rule out a chance of rain/snow mix in the valley during heavy showers. So it looks like we didn't get lucky this time but there still is the whole winter left!
As for next week, it is looking wet! just as this model shows the 72 hour precipitation totals.Over 10 inches in the Olympic mountains! and over 2 inches in the valley.

For skiers/snowboarders:
