This particular system is referred to as having a “wrap-around” effect. The moisture is tracking up from the south and driven toward the mountains by easterly flow. More snow tends to occur in Leavenworth and on the lower shoulders of the mountains than the Pass, which was the case last night and this morning. Snow will hopefully make it to the higher ridges today as the moisture content increases through the day.
Long-range: High pressure will begin to break up the clouds tomorrow night with Friday and Saturday trending dry and clear. A warm front arrives on Sunday/Monday which will likely produce rising freezing levels and a chance of some light precipitation.
