1/5/2012 Weather
General Discussion: Moderate snow showers will continue today under cool north westerly flow. The models have had a hard time nailing down the small disturbances imbedded in this mini storm cycle. The cut off low mentioned yesterday, is now expected to slide to the south into Oregon – thus, we should see a relatively dry day tomorrow.
Long-term: Models now have most of the moisture nudged to the north of Stevens Pass for the weekend. We may get some spin off snow showers from time to time but no significant snow accumulation is expected after today. Another SW warm air event will once again raise freezing levels above Pass level on Sunday / Monday.
