The snow of the past 24 hours has ended across the interior mid-Atlantic and southern New England. A few inches blanketed this region, with some receiving close to 6 inches when all was said and done. It'll still around for a few days, but with a milder weather pattern unfolding this weekend, it will sooner or later all but disappear.
With the minor storm gone, and none to follow through the weekend, our attention turns to the West Coast. The first in what will be yet another series of upper-level disturbances to crash into the West is already spreading rain into central and northern sections of California, and it'll rain hard there much of today before ending later this afternoon and early tonight.
The next surge of moisture will hit a little farther north late tonight and tomorrow, largely north of the Bay area, and will have more of an impact on western Oregon initially. However, with time, as a weak cold front inches southeastward through the region tomorrow night into Friday, the heavier rain will move south and east as well, inundating much of southwestern Oregon and northern California. Through Friday evening between the two features, some places will get a solid 5 or 6 inches of rain. Here's the latest forecast from the NAM through 6z Saturday:
Even as that feature begins to fade going into Saturday, still another will take aim at the Northwest, spreading rain and mountain snows into western Washington and western Oregon later Friday night into Saturday morning before it moves inland and weakens.
And that won't be the end. Perhaps the strongest feature of the bunch moves inland across southern Oregon and northern California Saturday night into Sunday with even heavier rains, and a lot of snow in the mountains. Here's the GFS surface forecast for Sunday afternoon:
That particular storm will bring enough dry air inland behind it for there to be a break in the action for the West Coast, but not for long, as more rain is likely by Tuesday along the Northwest coast, spreading southward into northern California Tuesday night and Wednesday. However, as the stronger lead system crosses the northern Rockies out into the northern Plains late Sunday and Sunday night into Monday morning, it will pull even warmer air out of the Rockies out into the Plains, pushing temperatures toward record levels.
This is the warmth that will move into the East early next week, though the departures from normal there will pale in comparison to what will be felt out on the Plains this weekend into Monday.
