Friday March 4
There's lots of WIND and rain on the way, and yes, plenty of mountain snow.
Today will be pleasant and dry, before a wet and blustery weekend arrives. California will be slammed with potentially damaging wind and heavy rain late Saturday; strong wind over Oregon. Cool showers to follow the front, so no drying expected into early next week.
Overnight Monday another system will approach the PNW, so rain returns. Wednesday night a strong storm will skirt up the coast, ushering in more WIND (esp NW WA) and rain across the region. No break in the action because early Fri a powerful storm may strike the west coast yet again. Therefore, strong WINDS, heavy rain and piles of mountain snow (blizzard type event possible) over an extended period from Fri Mar 11 through late Tue Mar 15.
The rain bucket will get full. Vancouver Island will continue to be slammed with rain as the week of Mar 14 ends, the rest of the PNW may get a tiny break in the storm action. The weekend of Mar 19, 20 in trending WET, BLUSTERY.
Generally, the rough weather will benefit the snow pack for all of the west coast. At the valley level, colder air this time of year usually presents heavy showers after passage of the cold fronts, with HAIL possible. Travel over the mountains will be a challenge. Rufus
