Weather Synopsis for Wednesday & Friday
A low to our west will track northward toward the central British Columbia coastline by evening. The associated trough will bring strong crest-level wind to many areas, peaking in the early afternoon, with light to moderate precipitation at generally elevated snow levels west of the Cascade Crest. Cold air east of the Cascade Crest will gradually erode from south to north, but it will remain in place long enough for the easterly flow to keep Snoqualmie Pass snow until 11 AM before a shift to rain (possibly mixed with freezing rain). Stevens is likely to stay mostly snow. Mt. Baker will be most favored by the southerly flow pattern, followed by Paradise and Crystal, then Hurricane Ridge. The Cascade passes will experience generally lighter precipitation.
The easterly flow will decrease Wednesday night following the passage of the shortwave trough and without much cooling aloft, snow levels will remain elevated in most areas with further erosion of the cold air east of the Cascade Crest. Stevens Pass should change to rain by about daybreak on Thursday. SW winds should generally decrease Wednesday night through Thursday.
A warm front will brush the region on Thursday, bringing generally light rain and snow on a southerly flow.
Thursday night and Friday should see some clearing as most of the weather action stays to our west and a ridge centered over eastern Washington and Idaho builds over the region.
