Weather Synopsis for Saturday & Sunday
A strong front blew through the Cascades early this morning and snow levels have dropped into the 1500-2000 ft range. Roughly 4-12 inches of snow has accumulated along the Olympics, Mt. Hood, and the west slopes of the Cascades with lower amounts east of the Cascade crest. The highest totals closest to a foot can be found at Mt. Baker (manual observation as the 24 hr board is out), Paradise and the top of Alpental. West winds continue to be strong at many locations following the front. Post-frontal showers should continue today with gusty westerly winds slowly tapering down in the afternoon. It's hard to say who will see some sunbreaks this afternoon other than the areas further east of the Cascade crest and perhaps the Hurricane Ridge area. Disorganized convergence bands may locally enhance snowfall totals in the mountain loop to Stevens Pass corridor today.
Showers should become lighter and more scattered tonight as snow levels remain cool. A front approaching the area from the west on Sunday should spread light snow inland during the day. Snowfall amounts seem modest at best as the front passes through in the early afternoon but there should be another significant uptick in wind prior to and following the frontal passage. A stronger system is on tap for Monday.
